Our take on the Definitive Technology ProSub 1000 by Crutchfield's Kristen Schaub
Double the thrill with room-thumping bass
Definitive's ProSub 1000 brings all of your movie soundtracks and music to life with high-impact bass. A front-mounted 10" 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 12" 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 1000 in with the rest of your system.

Overview: The Definitive Technology ProSub 1000 is an advanced state-of-the-art technology powered subwoofer with a built-in high-power, high-current amplifier and sophisticated electronic crossover, in combination with an active front-firing 10-inch high excursion woofer and 10-inch bottom-mounted passive radiator for massive bass with superior speed, control, and detail. The Definitive Technology ProSub 1000 is a compact, high quality, powered subwoofer that can be used in your home theater or music speaker system.
Passive Radiator Design: The ProSub 1000 features a 300-watt (RMS) amplifier driving a high-excursion 10-inch front-mounted direct-radiating woofer that is pressure-coupled to a 10-inch low-bass passive radiator on the bottom of the enclosure. The net radiating area of the ProSub 1000 is 39% greater than a single 12 inch woofer but with better speed, pitch definition, and control.
PowerField Technology Amplifier: The ProSub 1000 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 1000 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 10" polymer subwoofer driver is specifically engineered by Definitive Technology to deliver rock-solid low distortion bass, reaching down to the lowest subsonic frequencies (18-150Hz), 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 1000 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 1000 features two protection circuits that ensure that the subwoofer can never be overdriven.
Integrated/Adjustable Feet: The ProSub 1000 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.
Volume Control: The ProSub 1000 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 1000 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.
Note: The low-pass crossover is only supported by the powered subwoofer's speaker-level inputs.
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 1000 powered subwoofer has a complete range of inputs and outputs to allow easy and effective hookup to any system. The ProSub 1000 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 1000 also features speaker level outputs (binding posts), so you can connect your front (main speakers) through the powered subwoofer. The ProSub 1000 has a built-in speaker level high-pass crossover preset at 80 Hz (6dB/oct).

A decent Sub-woofer which packs the punch [ Ketan May 30, 2018 ]
I was a bit torn between the ProSub 1000 and ProSub 2000 supercube, but the larger driver of the 1000 is significantly richer than the 2000. I just notice a bit of pingy resonance in the 2000 on an action movie track that the 1000 just seemed to make the room shudder with but breathe easy...much much nicer sound! [ New User May 14, 2018 ]
Def Tech makes good stuff. [ Sagar May 10, 2018 ]

I needed a sub with speaker In and Out terminals... I also have Definitive Mythos ST Towers for my mains and a center channel for my home theater down in my family room...I like Definitive Audio products...they perform and they're reliable!

customers review [ L Jun 24, 2017 ]
The pro sub 800 sounded great just wanted more bass so im going with the pro sub 1000. What a great upgrade with definitive technology, thanks again crutchfield. [ TIM J Jun 24, 2017 ]
have had great luck w Def Tech in past, this sub gets lower than most in this price range and bottom bass radiator coupled with front firing woofer should provide excellent room filling sound [ Stephen Jun 20, 2017 ]

quality and price [ LUIS Mar 20, 2017 ]
Needed to replace my Paradigm PDR 10 Subwoofer and liked the specifications and reviews on the DT Pro Sub 1000. I use my subwoofer for watching movies and listening to multi-channel audio recordings.. The 300-watt amp + 10-inch woofer + 10-inch passive radiator should be able to provide the low distortion bass response I am looking for. My price target was in the $500 range and this subwoofer fits the bill. [ TIMOTHY Mar 17, 2017 ]
This has been a great little sub. The main reason I bought it after weighing it against other Crutchfield subs was the side mounted volume control. Several fit the bill sound wise but the volume feature makes it so easy to fine tune music and then crank it up for movies. [ Chip Feb 26, 2017 ]
High user reviews [ Timotheus Feb 09, 2017 ]
Reviews and price. Brand reputation. [ ANTONIO Feb 05, 2017 ]
My present Infinity sub started randomly making ticking sounds so I need a new sub. The rest of my main system is Definitive Technology and I am very happy with them, so I decided to go with a reasonably priced Definitive Technology sub. [ John Feb 04, 2017 ]
Crutchfied technical support was very helpful and they knew there stuff. I call 3 times with questions and they were very polite in answering my concerns. There were a lot of subwoofers to choose from but now I feel confident that I picked the right one. Kristina was the one who helped me the most. [ M Jan 28, 2017 ]
great sound from a 10in sub [ Mike Jan 18, 2017 ]
Have use the equipment before and like the sound produce. [ J Dec 23, 2016 ]

Great deal on sale [ John Oct 31, 2016 ]
good deal [ JC Oct 31, 2016 ]
Great subwoofer for a condo.. [ Tsgt2007 Oct 30, 2016 ]
From research I did, product reviews and customer reviews. The price point was compatible with what I felt I should spend for a decent system. My only reservation is the sub. I like deep, clear, and accurate bottom. Finally, I feel it will match up well with my Marantz SR7008 AV receiver. [ Robert Oct 25, 2016 ]
I picked this sub because of the many positive reviews at many different sites and the advise of a Crutchfield advisor. This sub should work well with my current system and also as i upgrade. [ M Aug 06, 2016 ]

2 questions already asked
Yes this sub will blow your room away. You wont need a second sub. When l first had my system going , my wife cleaned the sub. My wife unknowingly had turned the dial on the side of the sub up to full capacity. What a sound. When an explosion went off, she screamed, jumped out her seat and ran. I have a 360 square foot room with 10 foot ceiling and it is carpeted, l had put a 3/4 inch piece of plywood under the sub to direct the sound up more. After that it sets on the carpet. The sound isn't muffled at all and l still can rattle the walls. [ Richard Nov 26, 2017 ]
It will work great alone. Two are always better than one. Great sub. Can't go wrong. Highly recommend! [ William Nov 24, 2017 ]
Hi Chris: In my humble opinion the Pro Sub 1000 will not supply enough bass for a bi-level room. I use mine along with an SVS SB 1000 sub in a large single level room and the bass is amazing. You may be able to use Svs sub alone as it has more power than the pro sub. The SVS ofcourse is more expensive. [ Lynn Nov 24, 2017 ]
I live in a stand-alone house and drive my 5.1 sound system at a level just below the threshold of vibrating the glass out of the windows. I use my ProSub 1000 with Boston Acoustic fronts and center to play Fios TV and BluRay movies. Some music. The ProSub performs flawlessly, and like butter. Best sub I've ever owned. If you are a sound engineer or club musician or are just trying to break your apartment lease, a larger subwoofer might be slightly better than the ProSub 1000 (money no object). I buy everything I can from Crutchfield because of the quality of their people and their support. Unless your expert says differently, and your needs are similar to mine, I have no hesitation recommending the ProSub 1000 to fit seamlessly with any other brands of surround speakers. Full disclosure: I had a very bad experience with a Klipsch powered subwoofer a few years back, unfortunately NOT from Crutchfield, and will never buy another. [ Mark Jul 03, 2017 ]
I would have to think it match up well and sound terrific just as it does with my polk audio speakers. Excellent sub, get it!!! [ DORAN L Jul 02, 2017 ]
