Unique woofer design for big bass

Add the excitement of deep, rumbling bass to your home theater with Definitive's ProSub 800. A front-mounted 8" woofer works together with a pressure-coupled low bass radiator on the bottom of the enclosure to produce hard-hitting bass. The combined output of this pair is comparable to that of a traditional 10" woofer, but with greater speed, musicality, and control. The woofer is encased in an incredibly rigid basket engineered to hold the massive magnet structure and large voice coil in absolute alignment. And the non-resonant cabinet uses multiple internal bracings to make sure that you hear clean bass without sound-muddying vibrations.

Advanced crossover system


A 300-watt amplifier and advanced crossover ensure accurate bass response. The continuously variable low-pass crossover allows you to precisely control the frequencies that your subwoofer handles. And the built-in high-pass crossover is a nice touch: it prevents your main speakers from overloading with low frequencies if you hook them up through the subwoofer's speaker-level outputs. A side volume control makes adjustments fast and easy, so you can seamlessly blend the ProSub 800 in with the rest of your system.

  • bass-reflex (passive radiator) enclosure
  • 8" woofer pressure-coupled to an 8" low bass radiator

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Product Research



Passive Radiator Design: The ProSub 800 features a 300-watt (RMS) amplifier driving a high-excursion 8-inch front-mounted direct-radiating woofer that is pressure-coupled to an 8-inch low-bass passive radiator on the bottom of the enclosure. The net radiating area of the ProSub 800 is 27% greater than a single 10 inch woofer but with better speed, pitch definition, and control.

PowerField Technology Amplifier: The ProSub 800 incorporates Definitive's proprietary PowerField technology, by which the amplifier is specifically engineered in conjunction with the driver for optimum load matching and power transfer characteristics. The Definitive ProSub 800 powered subwoofer incorporates a unique, patented, digitally-coupled infinite power source amplifier with a high-current direct coupled power supply and discrete MOSFET output devices to ensure perfect high-definition resolution and reproduction of the most dynamic program material and demanding sub-bass transients. Construction quality is absolutely state-of-the-art, with only the highest quality components used including mil-spec glass epoxy circuit boards and precision resistors and capacitors for many years of faultless superior performance.

High-Definition Subwoofer: The powerful, high-definition 8" polymer subwoofer driver is specifically engineered by Definitive Technology to deliver rock-solid low distortion bass, reaching down to the lowest subsonic frequencies (20-150Hz), with superior transient response. The special ultra-stiff, low-mass cone (for super-fast transient response) is joined to a specially formulated surround and long-throw voice coil and spider. The ultra-rigid basket is engineered to hold the woofer's massive magnet structure and large voice coil in absolute alignment. The high temperature voice coil is made of aluminum wound with triple insulated ultra-pure copper wire and baked in epoxy for increased power handling.

Non-Resonant Cabinet: The cabinet of a loudspeaker plays a large part in its sonic performance. Resonance and vibration can add unwanted distortion as well as drain away important energy from the system. The Definitive Technology ProSub 800 powered subwoofer utilizes a monocoque cabinet, which has been specifically engineered to be totally inert and vibration free, to ensure you of pure sonic reproduction. Monocoque means that the cabinet is of a unitized construction where all panels are permanently joined together into one solid structure. The cabinet walls themselves are high-density medite fused together by space-age polymer adhesives. The front and rear baffles are extra thick and the cabinet, itself, incorporates multiple internal braces to ensure total solidity.

Protection Circuits: The Definitive Technology ProSub 800 features two protection circuits that ensure that the subwoofer can never be overdriven.

Integrated/Adjustable Feet: The ProSub 800 features four integrated feet with rubber tips so you can place it securely and safely on your home's floor. Each foot's height is adjustable to help you place the powered sub on an uneven surface.

Placement: The Definitive Technology powered subwoofer has been designed to operate at frequencies generally below 150 Hz. Because low-frequency information in this range essentially is non-directional, your subwoofer can be located anywhere in your listening room that is most convenient. Also the continuously variable low-pass filter operate at a very fast roll-off, ensuring great performance wherever you place the subwoofer. There are, however, some general rules that you should bear in mind when locating the powered sub.

  • For maximum output the subwoofer should be placed in a corner or against the wall.
  • Corner placement will increase the subwoofer's efficiency, which in turn will increase your system's maximum output and improve the dynamic capability of the subwoofer.


Subwoofer Controls: A complete array of controls allows the ProSub 800 to be perfectly integrated with any stereo or multi-channel audio system, and tuned for optimum performance in any room.

Volume Control: The ProSub 800 features a convenient front-side-mounted volume control that makes adjustments fast and easy. This precision level control allows you to perfectly adjust the volume of the subwoofer to match your system and room as well as to fulfill your own personal sonic preferences.

Variable Low-Pass Crossover: The Definitive Technology ProSub 800 powered subwoofer has a continuously adjustable low-pass filter control which allows you to choose a roll-off of from 40 to 150 Hz for the high end of the subwoofer. This unique "dual stage" roll-off (24dB/oct) is extremely steep which ensures perfect blending with your main speakers as well as eliminating unwanted midrange from the subwoofer. This is especially important because it gives you much greater flexibility in placing your subwoofer in your room without being able to hear where it is located.

Auto Turn-On Circuit: The powered subwoofer has a special power circuit which automatically turns the powered subwoofer on when a signal is fed to the loudspeaker and turns it off when there is no signal present, so it does not require an on-off switch.

LED Indicator: The red LED on the back panel of the powered subwoofer will light up when a signal is sensed and the amplifier turns on. It will automatically turn off with the powered subwoofer, a little while after the signal is discontinued.


Line-Level & Speaker-Level Connections: The Definitive Technology ProSub 800 powered subwoofer has a complete range of inputs and outputs to allow easy and effective hookup to any system. The ProSub 800 has a separate direct-in LFE low-level input. Speaker level inputs are provided in case you do not have a subwoofer output.

LFE Input: The Definitive Technology powered subwoofer has a low-level direct LFE input for Dolby Digital soundtracks, which bypasses the crossover network. If you are connecting the subwoofer to an AV receiver without a dedicated subwoofer or LFE preamp output, but does features a stereo RCA output, you will need to use a stereo RCA cable along with an RCA Y-adapter.

Note: When using the LFE input with a receiver that has an internal x-over you should set the x-over on the sub to 150Hz.

Speaker Level In: The Speaker Level inputs (binding posts) are designed to be used on receivers or amplifiers that do not incorporate any RCA type subwoofer outputs. If your receiver is equipped with an RCA type subwoofer outputs, these speaker level inputs should not be utilized.

Speaker Level Output:The ProSub 800 also features speaker level outputs (binding posts), so you can connect your front (main speakers) through the powered subwoofer. The ProSub 800 has a built-in speaker level high-pass crossover preset at 80 Hz (6dB/oct).

subwoofer enhances music

Written By Chip, Texas on Friday, February 13, 2015

Crutchfield Customer Review (What's this?)

Although I have a highly regarded brand of electostatic floor standing speakers, I felt at times like I wasn't getting enough base so, with some Crutchfield consulting, I purchased the Def Tech Pro Sub 800. Strictly for music. I have accomplished my goal and now my listening is more enjoyable with the underlying deep base of this sub. I am not an audiophile so I'll dispense with the numbers. It just sounds good! At above 25% volume I can now play without Tone Enhancement to more fully realize the immense clarity of the mid and upper ranges of my speakers and still have very adequate base.

Pros: Everything I expected.

Cons: None

Quality Sub!

Written By George, San Jose, CA, California on Friday, December 12, 2014

Crutchfield Customer Review (What's this?)

I previously have had Klipsch subs yet every 3 years or so I have to replace them because the amp or crossover fails. When my Klipsch KSW 10 failed, I purchased this Definitive Technology Sub and love it. The bass comes thorough very well without being "muddy".

Pros: Clean Bass that comes through very balanced at all volume levels!

Great buy!

Written By Mattb, Richardton, ND on Friday, September 12, 2014

Crutchfield Customer Review (What's this?)

I was a little worried this sub would be too small being only 8 inches. The Crutchfield adviser I spoke too assured me "it has some thump". I am very pleased with my decision to trust his advice. It is a great addition to my theater room sound system. Highly Recommended!

Pros: Excellent and very clean base.

Cons: None


Written By Richie, San Diego, CA on Sunday, August 31, 2014

I'm planning on building a 5.1 home theater system and so far I think this sub will be suitable for my current apartment, next A/V receiver.

Pros: So far it meets my power punch level and budget. So far so good.

Cons: Nothing to report yet.

Sub Love

Written By Old Guy, Birmingham AL on Tuesday, August 26, 2014

Crutchfield Customer Review (What's this?)

My tastes generally run toward clean crisp sound rather than a ton of bass but for movies and even for certain types of music this little guy can't be beat. Very impressed with the depth it adds to films in a compact size and price.

Pros: Plenty of power and clarity. It will fill a good size room with no problem.

Cons: I bought a scratch and dent and the information on the back plate is upside down. No issue but it is funny that they actually manufactured it that way.

Crutchfield Customer Review (What's this?)

Just purchased this Sub to replace a Polk PSW111 which I would rate 1 star for reliability as the amp kept breaking. I guess you get what you pay for. Anyway, so far so good with the DA Prosub 800. Nice smooth bass. Fills the room which is about 15' x 20'. In fact the bass is so powerful that I had to move it off my bookshelf as it was causing the objects on the other shelves to vibrate and rattle. This was at only a 40% setting. The down firing driver requires some placement consideration since the bass can get transmitted through the floor. Overall very happy with the purchase so far. I took off one star because it does not have a phase shifter swith.

Great Sub

Written By Anonymous, Columbus, OH on Tuesday, August 19, 2014

Crutchfield Customer Review (What's this?)

I exchanged a Polk PSW-111 for this and I could not be happier, soooooo worth the extra money. You can see by the spec that the frequency range is a lot lower than the Polk and it is incredibly evident. As someone who listens to a lot of electronic music with deep bass lines this was important to me and totally changed the listening experience. I also listen to jazz, funk, and rock and it also handles those genres incredibly well delivering tight bass that can be heard and felt. For every genre of music the bass is very full, tight, and pleasing. Bass lines are punchy and articulate even at lower volumes. The mid to low volume performance of this sub is another place it shines. It produces clear bass and does not have to be turned way up to do so. I should also mention that my listening area is fairly small at about 20 x 15. That being said I feel as though it would be ample even for a space quite a bit larger unless you are trying to shake your foundation/blow your windows out. I'm sure there are nicer subs but they also probably cost quite a bit more. As far as bang for your buck this sub comes highly recommended, worth every penny.

Pros: Full range. Tight articulate bass even at lower volumes.

Cons: For the price, none.

It's a nice subwoofer

Written By Mike, Cedar Park, TX on Thursday, August 07, 2014

Crutchfield Customer Review (What's this?)

This is only my second subwoofer. It doesn't have any shortcomings that I am aware of. It fits (barely) inside my media console (wife didn't want to see it). It sounds great. It is capable of being felt and can penetrate sound-proofed walls at high volumes but we generally don't listen to it that loud. No distortion. Does a great job complimenting our sound bar (Definitive XTR-SSA3).

Pros: Size, sounds great

Cons: Price

A whole new world

Written By kermit88, New York on Wednesday, June 04, 2014

Crutchfield Customer Review (What's this?)

I inherited a pair of KEF Q70 speakers, they have remarkable clarity. Unfortunately, by themselves they lacked commanding bottom. I listened to several subs from Polk, KEF and Definitive. The ProSub 800 was perfect. I am able to adjust the crossover point and volume and it sounds great. I had zero issues, and it has been a blast tweaking the two settings. I originally intended to set it up with the pre-amp out into the sub. In the end, it sounds better by taking the amplified speaker output into the sub, then back out to the speakers. There is still some low end coming from the KEF's, but the sub-woofer is producing 80% of the boom. I'm really happy with my new Sub, and recommend it highly.

Pros: Great clean boom, plenty of adjust ability. Nice price point.

Cons: none so far.

Full, clean bass response from a diminutive package

Written By Jorge S, Bluffton, SC on Thursday, May 29, 2014

Crutchfield Customer Review (What's this?)

Excellent, clean bass that you can feel. I was a little skeptic about the SUB800's ability to produce usable deep bass, but I am most impressed. No, it does not produce the thundering bass that would make action films pop in even the largest of media rooms. It does however match up very well with my Polk Audio RCi in-walls in my family room: a 23' L X 18' W X 21' H room. Sits almost invisibly behind a side near a corner to the right of the FR speaker and produces tight, clean base. I have yet to over drive it. My main concern was to keep the modern, sleek, mid-century decor in my home, and this was a very nice compromise between size, aesthetic, and performance.

Pros: Appearance, value, sound, auto on / standby function, build quality

Cons: A little pricey


Written By JayMar, Chandler, AZ on Thursday, March 27, 2014

Crutchfield Customer Review (What's this?)

My initial goal was to find something small enough that could hide away in a cabinet (wife's wish), but still have enough oomph to be close to or better than the Klipsch Synergy 10" it was replacing. I tried Velodyne first (Impact 10) and wasn't impressed, it was just as boomy as the Synergy. I tried a Polk second (PSW111) and it lacked the power and depth I was looking for. I have always been impressed with my Definitive Tech center channel and after a lot of review I decided to give the ProSub 800 a try and I have been very, very impressed with the results. Sound is much more tight and precise than the Klipsch and somehow this 8" sub gets just as low as the 10" Synergy does. I have been equally impressed with Crutchfield, I ordered the ProSub 800 under the Scrath and Dent and when the first one showed up I had a feeling I was in for trouble. Upon opening the box it looked like someone threw a party on top of the sub, foot print on the speaker grill, pieces rattling around on the inside... after plugging it in there was no sound. Crutchfield replaced it very quickly and the second that showed up was in outstanding condition and works like a charm.

Pros: Sound is superb, I thought the SuperCube 2000 was going to be what I needed, but this is absolutely perfect for my needs.

Cons: The white fabric speaker cover can get dirty easy... but it's white what do you expect just wash your hands and you'll be fine.


Written By Alex, Boston, MA on Thursday, February 27, 2014

This sub replaced a DCM 10" sub that is about 11 years old. The old one works well but this ProSub 800 is killer. Its range is wider and when placed in a corner it really shines. If your hesitant to get an 8" sub as I was DONT BE. This sub rivals any 10" sub I have herd. I still have to break this sub in but it sounds incredible out of the box as long as you set it up properly. I have it paired with the promonitor 2000 center and 1000 surrounds up front. My rears are smaller speakers. I also purchased this as a scratch and dent. Hardly! The original box only had a couple minor scratches on it. If you want to pay extra money for a box in perfect order the go for it but the scratch and dent deal is the best. The sub inside the box is in perfect condition. Just get this sub and be happy.

Pros: Simply Great!

Cons: None

Written By Bill, Westminater, SC on Sunday, February 23, 2014

Crutchfield Customer Review (What's this?)

Highly recommended by the Crutchfield representative. Worth every penny. I really like it, a lot.

Pros: When we first hooked it up, had the volume turned up and thought that we were having an earthquake. Puts out a lot of sound for an eight inch driver. Nice small foot print.

Cons: None

Crutchfield Customer Review (What's this?)

Bought this sub to replace 12" Polk that was taking up too much space. Very good sound; however, inadequate replacement for 12" Polk. For an 8" sub it does produce very good bass. I returned it and kept the Polk.

Pros: Good bass; good shape (footprint).

Cons: Bounces on hardwood floor; price; does not produce like a 12" sub.

Good little Sub

Written By Michael, Fairborn, OH on Saturday, February 01, 2014

Crutchfield Customer Review (What's this?)

I bought this sub to add to the two channel setup of Definitive Technology ProMonitor 800 speakers. This is a great little subwoofer that matches the ProMoniter speakers. The sub adds the right amount of bass to the little bookshelf speakers. If you are looking to add some high quality bass to a small speaker system, these will do it for you.

Pros: Small, good bass quality for the size of the subwoofer.

Cons: I little expensive, but worth it.

Lots of bass from a small sub

Written By JeffN, Van Buren, AR on Wednesday, January 15, 2014

Crutchfield Customer Review (What's this?)

I am impressed with the amount of bass from this small sub. Fills the room when listening at moderate volumes. Gets boomy pretty quickly at louder volumes.

Pros: Relatively small, sounds great at moderate volumes

Cons: Gets boomy pretty fast in movies at loud volumes

Nice but a little "alll or nothing" at times

Written By BReeves780, Nashville, TN on Sunday, December 29, 2013

Crutchfield Customer Review (What's this?)

I bought 2 Mythos Six and a Seven along w/ a ProSub 800 for center, side & sub speakers for a new Samsung plasma and although they're still new to me, I really like the sound of the outer speakers. The Sub is a little bit "all there or not" but the Mythos' are all great...look and sound terrific.

Pros: Nice look, compact

Cons: For TV, the bass is sometimes very loud and boomy and on other shows/movies, its virtually silent. I've played with settings and EQ but can't seem to get it right...they are brand new & just set, so I've not found my preferences yet...I'm sure it will work out eventually...

Definitely the best

Written By Bob h, Palmyra, VA on Saturday, October 19, 2013

Crutchfield Customer Review (What's this?)

Almost everything we listen to demands a good bass in order to give it substance. Without the ground bass line in music it seems anemic. Every action movie has a great deal of work for a good bass speaker. Imagine an explosion without the bass to emphasize the depth of its sound. Yet the bass in music should be relatively unobtrusive so we can hear the melodic line of that music. The Def Tech does just that. The bass line is smooth and punchy and if you listen for it exclusively you will definitely hear it. But if you listen to the melodic line you know it is there but it doesn't interfere with the enjoyment of the melody. I've had a couple of bass speakers, both powered and not, and this is definitely the best I've heard. With a lower level of 20 hertz it is somewhat below the ability of the ear to pick up so it is more felt than heard, which in some movies is what you want. I'm definitely sold on this bass and would recommend it to anyone who wants a smooth performer.

Pros: smooth yet punchy when needed

Cons: Can't think of anything bad about this speaker

Definitive Technology ProSub 800

Written By Luke, Bentonville, AR on Saturday, May 18, 2013

My Morel sub (two 9" woofers at 125watts) was a very good sub. Retailed for double the price of this pro 800. One of the woofers bit the dust. I thought I'd need another $800+ sub. The pro 800 was suggested for my some what smaller room. Turned on the avengers and set the sub a little below half, I was blown away. It's crisp and accurate, it's got the right amount of boom and punch but delivers it so smoothly, like bass butter. I knew def tech could make a sub but I honestly didn't expect this quality from an entry level sub at this price point. When I buy a house with a dedicated theater room I will probably buy another and run two 800s or a super cube. Given the 3 year warranty and quality this has been the best sub i have bought in this price range. I think an upgrade could be had at $600 but unles you have the space to fill you won't need to spend more or look else where. This sub is outstanding, period.

Running a denon 1913 receiver.

Pros: Amazing sound for a very small foot print. A great value in the world of subs. Def tech does not disappoint.

Cons: Would like to see 18hz for this price. Will distort at very high levels, you'd pay $1000 to get past this in any sub.

Booming Bass

Crutchfield Customer Review (What's this?)

I had a free Polk Audio subwoofer that was the victim of a power surge. I was very satisfied with the level of output it had, and is sounded nice in my living room with my Polk Surroundbar 50. I mostly used it for video games and home theater. I replaced it with this product, and the difference is dramatic. The room now fills with low-end sound, but it never feels intrusive. There are sounds in my video games that I never new existed. It has been a revelation.

While I am sad about losing my first sub, this is just magnificent

Pros: Great room filling sound, never obtrusive

Cons: Slightly larger than some

first off i had an infinity ps210 for 3 years. worked fine for about a year then nothing but problems with the amp. crutchfield worked with me the whole time to make it right. 2 new amps, replaced the whole unit but still the same problems. was going to replace it with the ps212 but mathew at crutchfield suggested the pro sub 800. glad he did. it looked small when i got it out of the box, but the bass coming out of the 8in sub sounds awesome. thanks again mathew and everyone at crutchfield for years of great service and support.

Good but Limited

Written By Tom, Rochester NY on Sunday, March 27, 2011

I've had this sub for about 2 years -- initially was in living room paired with Def
Tech SM350s and CLR2002 center -- very good for music, tight bass, blended
well with the other DefTechs -- but bottomed out occasionally with movie sound
effects, and had some difficulty filling the room evenly. Replaced it with the
ProSub1000 and moved it to the bedroom -- is excellent in a small room where
typically not high volumes. The stated frequency response is a bit of a push,
doesn't go that low.

Exceeds all expectations

Written By Dean, Fredericksburg, VA on Friday, November 20, 2009

Crutchfield Customer Review (What's this?)

Upon delivery of the sub, I was shocked and concerned with the size of the box it came
in. I was thinking, how can a unit this small give the results I am looking for? (It replaced
a Yamaha unit that was twice the size.)

Installation and set up was a breeze using the Audyssey mike that came with my Onkyo
SR 706 home theatre receiver. The size of our viewing area is 15' X 20'.

The results are that this unit provides ample, distortion-free bass that changed the whole
tv viewing or music experience. It is quite responsive to movie segments that require
wall thumping sound. But on the other hand, it is not so overpowering that you cannot
hear the finer nuances in the soundtrack.

Bottom line is that you will not be disappointed in this unit.

Great little sub.

I owned an Infinity PS210 subwoofer and initially I believed it was sufficient but after watching some of the Transformers movie, I knew I was not getting the lows that were possible with a subwoofer. I did a lot of research and figured what I was missing was something that went down to 20 hz (the Infinity is rated at 27 hz).

I purchased the Prosub 800 (rated at 20 Hz) and another sub ($600). The $600 sub had a nicer sound; smoother with music and if you turned it up, it could literally shake the walls during explosive movie scenes. It was the "better" performing sub, but I decided to keep the Prosub 800 because 1) it's less expensive 2) the Prosub was right there sonically. It didn't sound as good as the other, but it did sound very good. Music was tight and movies scenes came alive (the walls didn't shake, but that's probably a good thing). It had none of the boominess of the Infinity PS210 3) the Prosub is tiny. Rather than have a small water heater like the $600 sub in my living room), I have the Prosub totally out of sight. Great when you have the wife factor.

Given how good the Prosub 800 sounds, I imagine the 1000 and Supercubes only improve on the movie and music listening experience.
