Built with quality materials that are made to last

The key to the PS410BK's remarkable performance is its MMD® driver. This material uses a solid metal core which allows the woofer cone to keep its shape as it moves back and forth — resulting in clear, accurate sound, even with the most demanding music and movie soundtracks. The black woodgrain vinyl finish fits in with almost any room decor.

Build a complete Primus® system

The Infinity Primus PS410BK will fill most rooms with dramatic and well-defined bass. Connect it to your receiver using either the LFE or line-level inputs. Easily accessible controls on the back of the sub help you blend it in with the rest of your system.

not long lasting

barkley from winchester ky on 5/22/2016

only lasted two years. amp got very hot and started popping and cracking and died

Pros: sounded great

Cons: short life span

Infinity Primus PS410BK

Infinity from St. Pete, Florida on 2/11/2016

Excellent bass response. I love it.

Pros: Great price and a excellent sound quality. I have it paired with the p363s.

Cons: Just a little bulky

Still a flawed product

Chris from San Mateo, CA on 2/8/2016

Crutchfield Customer Review (What's this?)

As many other reviewers have noted, this sub has a habit of failing after roughly 6-18 months due to the high temperatures ruining the power supply capacitors. This is a design flaw that Harman appears to have decided not to correct. I therefore cannot recommend this product. I wish I could return mine.

Pros: Good sounding sub woofer, well priced.

Cons: Fatal design flaw means the amplifier will fail at some point. Don't buy.

Powerful bass!

Andrew from North Carolina on 1/18/2016

Crutchfield Customer Review (What's this?)

I purchased the PS410BK to add the final piece to my home theater. I have an average size room with very tall (25ft) ceilings and his sub provides more than enough bass to fill the whole room! Great value and comparable to much more expensive subs!

Pros: Clean, responsive bass with great price tag.

Cons: A little bulky

Where's the Quality Anymore??

Matthew from Ohio on 12/23/2015

I own two of these subs and both have died now. One after 13 months and one after 9 months. I bought one as an open box deal that came without a warranty, so I'm out of luck with that one. The other is at Harmon in California for warranty replacement. They make you ship the entire subwoofer back to them instead of just pulling the amp out of the back, which would be much easier for most consumers. From what I've found, by searching online, is that the circuit board under the two large capacitors over heats and melts, regardless of how hard you push the amp. Both of mine were set at 50% percent and not used often. They both started making a hissing/crackling sound when the problems began. Some people have reported screeching and popping sounds when theirs started to die. Amplifier warranty is 2 years, so you make get one or two fixes before your out of luck. Also, from what I've found is that you get one back just like the one you sent in, flawed. So you can expect the new one to die in about a year as well. I'd love to recommend another brand that might be better, but it seems like all you can get is junk anymore, regardless of price. A friend at work bough a Martin Logan Dynamo 1000 and his amp died after a few months as well. I have a 12 year old Sony SA-WM40 that is still going strong, but I wouldn't recommend Sony anymore either.

Pros: Deep, clean bass for movies.

Cons: Quality, longevity. Lacks punch and clarity for music.

Dangerous piece of Junk

Kyle from Texas on 10/8/2015

Before you buy this or any other sub from Harmon, google blown or fried Infinity or JBL amp. These subs have been having these issues since around 2010, and it doesn't look like anything has been done to resolve it. I set up my sub and amp properly and never had the gain higher than 50%. It resided at 40%. I used it for probably less than 30 minutes per day on average. I bought the sub in March of 2013. During the past week the subwoofer started making a popping sound. I troubleshot everything I could think of to no avail. Yesterday, I was using a multimeter on the power sourece to make sure that the issue wasn't due to an electric supply inconsistency. Due to being behind the subwoofer at the time I started smelling a burning smell, when I looked at the back of the subwoofer, smoke was coming out of the back. I unplugged everything and pulled the amp out to find that one of the capacitors had blown the top off and there were severe black scorch marks on the circuit board. Had I not been in the room and that close to the subwoofer at the time, this could have caught fire and damaged my home. I've been trying to find a replacement amp, but nope- Infinity doesn't sell them. So if this does break, youre just out of luck. Apparently so many of these amps are blowing that there are people online advertising that they repair this specific subwoofer. I'm pretty irritated at Infinity for knowingly selling a faulty product, plus I'm 7 months out of warrant.

Pros: sounded good while it worked

Cons: Horrible history of product failure, had I not been in the right place at the right time, this could have caught my home on fire. Bad warranty that really only protects the part that is less likely to have issues

Hot plate amp

Dave from Fair Oaks, Ca on 8/9/2015

Crutchfield Customer Review (What's this?)

Love the sound! Sub was shipped quickly and arrived in perfect condition. I am very disappointed with the durability of the piece.the plate amplifier burned out while it was not in use. and the second replacement amplifier seems to be on its way with the amount of heat it produces.I saw all of the 5 star reviews and thought it was going to be a good unit. it is a shame I already had to get it repaired because it sounds so good.

Pros: Sound quality is fantastic for movies and the lows in music are superb. I listen to classic rock/ modern rock/ country/ a little hip hop. The lows that come out of this thing are lovely on the ears.

Cons: The plate amp had to be replaced after 8 months. The amp gets so hot you can barely touch the switches. after looking around online I read that the amp never turns is just as hot in the morning as it is at night after watching a movie. this seems like a major design flaw and I am worried it will fail again. knowing what I know now I would have bought a different one.

Incredible the difference a good sub woofer can make. I originally had an older Infinity subwoofer that stopped working and I replaced it with old Kenwood I wasn't using. I was ready to replace the whole sound system, no need now. It sounds amazing.

great sub woofer from las vegas,nv on 4/17/2015

Plug in and feel the movie ...

iNoteboom from Oviedo, Florida on 3/14/2015

Crutchfield Customer Review (What's this?)

I am writing this review, happily stating that this sub is great, fully realizing that I am not sure what a bad sub would be. I use a Denon AVR-X4000 to drive the Infinity Primus PS410BK, and the Denon setup pretty much dictate how and where to place the sub. And it works, very well. Family movie nights are engaging and room filling. A notable difference from when the sub is not on.

Pros: Plug in and the movie comes to life. Room filling sound

Cons: It's not the most beautiful piece in my living room, but after a few weeks, I don't even see it.

Big Boom!

Cvillain from Virginia on 3/12/2015

Love this sub! Replaced my old Sony sub w/ this one...hooked it up to a Denon receiver I bought from C'field around Thanksgiving. Also got an Infinity Primus Center channel. An amazing difference to the home theater. Love it!

Pros: Nice looking...great value...300w amp!

Cons: It's a 10" so you need to find a spot for it.

Great sound, but power supply buzzes

Lee from Colorado on 3/9/2015

Crutchfield Customer Review (What's this?)

These subs sound wonderful in a home theater setup. However, the amp seems to stay on 100% of the time if you have the auto-On LFE switched on, and the power supply buzzes, and stays warm...not terribly energy efficient. Have this in a quiet theater room, and the buzzing is noticeable when system is not on playing a movie. The rear panel stays warm 100% of the time, even when no signal and the red inactive light is lit (green is on indicator). Returned one sub to Crutchfield due to this problem which the tech identified as a defect, my replacement was nearly as bad...buzzing a little quieter, but still there, and rear panel stays warm. Crutchfield was wonderful with the swap out. Neither unit seems to switch on easily with the Auto-On LFE line level subwoofer feed from my new Yamaha Adventage Series AV receiver...and can take some manual coaxing...which is a pain in my setup since I have the unit in a hard to get to custom subwoofer enclosure so it isn't sitting out in the room. Like the sound, size and price, not too fond on the electronics.

Pros: Great sound, good price, nice size. Big rumble from a moderately sized box.

Cons: Amp always stays on with LFE Auto-On feature, and annoyingly buzzes, LFE Auto-On doesn't work well 100% of the may have to manually flip switches to coax unit to come on. Power supply stays warm and using electric even when off, unless you hard switch the unit off (LFE Auto-On doesn't shut down power supply).

Great subwoofer for the price

Awesome Sub

Don from Colorado on 12/23/2014

Crutchfield Customer Review (What's this?)

To round out my home theatre set up I wanted to add a subwoofer. I looked through the ones at Crutchfield and decided this was a good buy for the money. I have had it several weeks now and just love it. The bass is awesome and it really rounds out the lower end of my system. I absolutely love it and am very glad I decided on it. It is an awesome subwoofer! I highly recomment it!

Pros: Great bass sound and very easy set up

Cons: None

Booming bass

RonS from Delaware on 11/9/2014

Crutchfield Customer Review (What's this?)

This sub accompanies (2) Klipsch RF-600 floor speakers and a Klipsch Reference center speaker. It packs a powerful punch for all sorts of sounds from regular TV to music to movies, without being overbearing. Very nice.

Pros: Powerful. Thumps when you want it to, doesn't when you don't.

Cons: None.

Not 10" Driver

Kevin from Arnold, MD on 10/14/2014

Crutchfield Customer Review (What's this?)

I received the sub in the mail. Got here very quickly, kudos to Crutchfield for good shipping and logisitics. I got the PS410 to replace a seven year old Infinity sub that I really like, but the amp died. My old Inifnity was a 10" sub, the PS410 is not. The width of the actual cone is more like a tad under 8" and the width of the speaker, inlcuding the rubber ring around the outer circumfrance is 9". I am going to use the sub for a bit to decide whetehr to return it. A bit of false advertising by both Infinity and Crutchfield. I expected better of Crutchfield.

Pros: Attracitve, simple design.

Cons: Not really a 10" sub.

Crutchfield response on 10/20/2014 Thanks for your review. Subwoofer sizes quoted in the manufacturer's specs typically refer to the maximum diameter, measured from the outer edge of the speaker's rim or frame, not the edge of the speaker cone.

Powerful Subwoofer - Perfect for home theater and audio speaker system

GaryJ from Cherry Hill, NJ on 7/19/2014

Crutchfield Customer Review (What's this?)

I needed a replacement for a 10-year old Infinity subwoofer that died and together with Crutchfield advisers selected and purchased the PS410BK. I am more than satisfied with the PS410BK. The 10-inch woofer provides full low end frequency range. The 300-watt built-in amplifier provides thunderous sounds and makes you believe the action of the movie is right in your home.

Pros: Attractive cabinet style.

Cons: None

Great Sub!

This is a great sounding sub with deep bass, no boominess at all. A real nice compliment to my old floor standing Cerwin Vega's. I also have two other sets of Primus speakers, a pair in my workshop and another in my camper. Love them all..Good quality & great sound.

Pros: Good Quality, Great Sound, Good Product for the money

Cons: None

Adds some bump

Colin F from Iselin, NJ on 5/30/2014

Crutchfield Customer Review (What's this?)

Although slightly underwhelmed at first, after setting the crossover and level just right and positioning this sub correctly it does what I wanted it to do. I get less of a "push" from this sub, more like it just fills out that bottom end to make your music/movies sound complete. It may just be the acoustics in my room that prevent it from really thumping for me (very narrow rectangular shape). I do appreciate the tightness and responsiveness though. Build quality appears excellent and the sub itself is beautiful. I have it paired with a set of Infinity Primus floor standers hooked up to a Harmon Kardon 3770 HK, overall I am very happy with my system.

JerryH from Valley Center, KS on 1/29/2014

Crutchfield Customer Review (What's this?)

Let's face it, if you already have a subwoofer hooked up to your home theater system, and it works, why replace it? I mean, bass is just bass, right? Well, that's what I thought before getting this new subwoofer. My son wanted my old one., so this gave me the perfect excuse to order a new one. And who wants to disappoint their kids :) At 300 watts, this subwoofer really packs a mean punch. The difference between this Sub and the 100 watt Sony I replaced is very, very noticeable. Movies are just more fun to watch when you can hear everything as it is intended for a real theater.

Pros: 300 body punching watts. An adjustable crossover so you can decide how much of the higher frequencies you want to include. Left and right channel inputs, or the option for one channel. The size was just right.

Cons: When your spouse calls from upstairs to tell you to turn down the volume on the movie.

Bought this subwoofer as an addition to my home theater. It does a nice job of adding that extra bass that was needed when watching movies or listening to music. Very satisfied with this purchase, and the reduced price sure was an extra incentive.

Pros: Great price for a Great sound The compact size makes placement easier in tight situations.

Cons: None

Ominous intensity

Craig from Staten Island, NY on 12/25/2013

First let me begin by giving thanks to one of the best online retailers I've ever had the pleasure of working with. Without blowing sunshine up you know where, Crutchfield is head and shoulders above the rest. From its considerate, knowledgable and dedicated customer service, to its well trained professional tech support team, you have won me over for life! My home theater is my first stereo purchase in almost twenty years. With the help of the folks at Crutchfield The new system consists of: 2 Cherry wood Klipsch RB 61's placed on Sanus stands; 1 Klipsch RC 52 center channel a Sony Blue ray player and Denon 1913 receiver running the show. I don't presently have room for tower speakers and decided on minimizing, but not sacrificing the space. With the help of the Crutchfield dream team It has all come together. Since my initial purchase I have completed my 5.1 surround system with the ominously intense Infinity Primus 410BK. This subwoofer is a force to be reckoned with. It drives my system to the core of heart pounding bass. Not only with movies, but you will be thrown back in your seat by its true ability to take music to a level typically achieved only by subwoofers costing two times as much. I make this promise, you won't be dissatisfied. Buy this subwoofer, and start feeling what bass was meant to be felt like. It was one of the best investments I've made in my system. Infinity Primus 410BK We are soul mates. You complete me....

Pros: Deep heart pounding intense bass

Cons: None

Crutchfield Customer Review (What's this?)

great sub. I'm pairing this with other Primus fronts and center. The sound is great. Happy so far. Crutchfield is super in customer service. The site is easy to navigate; it has good product listing: specs, review, etc. The sub came in a well-wrapped package. I hope Crutchfield's accessory lines are cheaper or at least comparable to other sites so I don't have to go shop somewhere else for wires, plugs, etc.

Pros: good quality: sound great + heavy so i assume it's a real build

Cons: big


Mike D. from GA on 9/23/2013

Crutchfield Customer Review (What's this?)

Im using two of these in my home theater setup. They have good tight bass with little to no distortion. I am overall satisfied but they really should have came with speaker level inputs. A good sub for the price. Can easily handle a medium sized room. Finish if good but feels a little cheap (which it is). Does what it advertises.

Pros: Tight bass. low or no distortion.

Cons: looks and options reflect its price. (not really a Con)

Great Value, VERY nice!

mob status from STL on 7/26/2013

Crutchfield Customer Review (What's this?)

This is a great sub, for the money. I own a Pioneer Elite SC-65 and Polk RTi8 tower speakers. I was really surprised by the overall performance of the sub compared to my 8" Polk PSW111 and also my friend's 10" Polk. It seems to have a fairly flat frequency response, which is impressive for a ported enclosure. Clean power and an extremely efficient woofer. I have put this sub through a full battery of tests with various genres of music and there is really nothing negative that can be said about its performance. It does not do anything badly. Playing some tremendously bass heavy R&B demonstrates it can play loudly without sacrificing clarity. Even at very high volumes, it did not sound muddy. The lowest of frequencies this sub can register are not accentuated quite as much as the higher frequencies, comparatively speaking. However, this is to be expected of a 10" or smaller woofer. The positive side to this is the fact that the amp does not seem to try to force the woofer to play frequencies beyond its excursion limitations. This was proven by never hearing the sub bottom out. I can only assume that either the power handling of the sub is great, or its excursion is excellent. Please believe me when I say I did not take it easy on this sub in my testing, and it stood tall. All music types seem to do very well this sub. Did not test higher than 100 Hz because that is where my crossover is set on the SC-65. With proper tuning and placement, it will perform very well.

Pros: Overall frequency response, clarity, efficiency, value

Cons: Low end freq response could be better

Amazing bass!

Pros: Did what I had hoped for when I made the purchase.

I have owned Infinity speakers for years and come to expect the best in performance. I was not let down with this product. We have a Infinity 12" sub in our living room home theater setup and wanted more low-end for our rec room. This unit delivers all we ask of it and my wife and myself have commented several times to each other that we're glad we made the purchase, and should have made it sooner.

Pros: Awesome low-end and easy to adjust volume and crossover.

Cons: None.


Al M from Sykesville MD on 3/25/2013

Bought this over the phone from Crutchfield after the rep recommended this among several others I asked about. Mated this to two Infinity PS363's (reviewed them too). This subwoofer is Sweet! It thumps my floor when a bass drum hits, and it shakes the windows when a low note from an electric bass plays, or when the contrabass violin is bowed, or when electronic bass is synthesized. For my 450 sq ft room, it does the job. Mated with Infinity 363's so I turned the crossover control to its lowest setting as the 363s have good bass themselves. I have it in the corner of the room at 45 degrees so the port is facing the corner. Big sound from a small box.

Pros: Tight, not boomy bass at the very bottom end. Standby power mode, variable crossover, sturdy cabinet.

Cons: None that I have seen or heard.

Good subwoofer for the money. Had a 100 watt infinity before and fried it so I upgraded.

Product Research



Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Cascade series, M.M.D. features a stiff aluminum core, anodized on both sides for increased strength and rigidity. M.M.D. transducers conduct sound faster than paper, polypropylene, and Kevlar, pushing unwanted resonances beyond the operating range of the transducer. M.M.D. drivers deliver crystal-clear, distortion-free sound from dynamic digital sources, even at high listening levels. The PS410 is equipped with a front-firing, 10" M.M.D. woofer.

Surround: For a smoother response and improved durability, the woofer uses a rubber surround.

Amplifier: This subwoofer is powered by a 300-watt (RMS) amplifier, rated at 27Hz - 150Hz with no more than 0.1% THD. The maximum (peak) power output is 500 watts.

Bass Ports: There is one rear-firing bass port that allows deep bass with high acoustic efficiency and low distortion.


Gain Control: The subwoofer has a rotary control on the rear panel for adjusting the level of the bass.

Low-Pass Crossover: The subwoofer features a continuously variable 50Hz-150Hz low-pass crossover that determines the highest frequency at which the subwoofer reproduces sounds. The crossover has a 24dB/octave slope.

Note: The crossover is bypassed when the "LFE/Normal" switch is in the "LFE" position.

Phase Switch: The subwoofer's phase switch allows you to control the phase of the subwoofer's output relative to the front speakers. If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass "attack."

Auto On/Off Circuit: The auto on/off circuit turns the power amp on when a signal is sensed and turns the amplifier off and into standby mode approximately 10 minutes after a signal is no longer received. An LED indicator on the rear panel glows green when the amplifier is on and red when the amp is in standby.


Line-level Inputs: The subwoofer has gold-plated stereo RCA inputs with an "LFE/Normal" switch. If you have a Dolby Digital/DTS receiver or processor with a low-frequency-effects (LFE) output, you should switch the "LFE/Normal" switch to the LFE position. If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output, you should switch the "LFE/Normal" switch to the Normal position. In either case, you may use either the Left or Right input. A "Y" adapter is not necessary.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

To replace an older JBL sub woofer that hummed. The Primus also has an on/off switch which can be used to turn it off when I don't wish to use it. [ James  Sep 05, 2016 ]
quality and power. [ dan  Aug 26, 2016 ]
Recommended, one of the subs, Clarence, showed me. I licked the extra power capability, it had. [ Theodore  Jul 08, 2016 ]
In talking with Crutchfield expert, it was the right size for my room and purpose. It was going in a corner, on a rug, and had the best chance (for under $500) of delivering great movie experience. [ Peter  May 24, 2016 ]
I bought one of these a couple of years ago for my main home theater set up and loved it. Tight, clean bass w/plenty of volume, and best of all, musical. Was looking for the same sub to put in my man cave HT system, and found one in the Outlet store. No-brainer before, but at a reduced price even better! [ DONALD B  Mar 30, 2016 ]
good price for a 300 watt subwoofer. [ kenneth  Mar 12, 2016 ]
Great tech service and a good return policy. Stone was a great help [ Teunys  Feb 19, 2016 ]
10" is the must subwoofer [ Nishant  Jan 17, 2016 ]
Based on brand, price, size of woofer and reviews. [ JAVIER A  Jan 16, 2016 ]
good reviews [ Ricardo De  Jan 13, 2016 ]
Met my needs. [ Michael  Dec 31, 2015 ]
Great sub at a great price but the size is a problem. [ mitchell  Dec 16, 2015 ]

2 questions already asked

Mike, thanks for the heads up on amp problem. Went to Infinity website. No word on how or when fix will be done. Good news we have a 5 year warranty. [ JIM  Aug 24, 2016 ]
I bought two of these subs in 2012 (?). One of the subs started emitting random, EXTREMELY LOUD pops just at the end of the 2 year warranty period in 2014. Crutchfield sent me a brand new sub immediately. It's been great ever since. The other original sub has shown absolutely no problems. [ WILLIAM  Aug 24, 2016 ]
You sound well experienced with that, as am I. According to an Email I got last August when replacing a sub, they have a fix for it in place. Having said that, I received my replacement last August 8th or so; and I'm now starting to hear the telltale signs of failure - the slight distortion that will turn into full-blown within weeks. But according to my email; it's supposed to be corrected so I will be contacting that representative soon regarding my unit. [ SEAN  Aug 24, 2016 ]
I've had one failure that was replaced... A year or so, holding up so far. [ Christopher  Aug 24, 2016 ]
I forwarded your question to an Advisor and they responded with the following: The Ohm rating is not given on that sub, you will have to call Infinity directly 800-553-3332 If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
