Our take on the Polk Audio HTS 12

I've been a Polk Audio home theater enthusiast for years, having owned several different-sized Polk systems that I've loved. If I was building a new surround sound system today, I'd strongly consider the HTS 12 for my all-important bass production.

I've been a Polk Audio home theater enthusiast for years, having owned several different-sized Polk systems that I've loved. If I was building a new surround sound system today, I'd strongly consider the HTS 12 for my all-important bass production.

This hard-hitting sub can fill even large rooms with deep, responsive bass. My hunch? If you're like me, you may look forward to watching movies with family or friends, just to show them how good the bass sounds.

Polk Audio HTS 12 powered subwoofer

The Polk Audio HTS 12 powered sub features a sleek, rounded enclosure and a removable grille.

A new design adds visual interest

This sleek sub features a hip, updated design with rounded corners and a slot on the bottom that shows off the flared, down-firing port — a bit of a departure from Polk's previous enclosures. Cosmetically, it's my favorite Polk sub design to date.

But the HTS 12 offers more than just good looks. It pairs a 12", front-firing driver with a 200-watt amp for impactful bass from music and movies. Use it as part of a stereo music system, or as part of a Polk Audio Signature home theater system.

Fantastic Low Frequency

Anonymous from KS on 6/4/2018

Crutchfield Customer Review (What's this?)

Expensive, but worth it! This is an amazing piece of audio equipment. I'm experiencing bass with this one single sub that I never did before with two lesser subs. The one this 200 watt sub replaced was 250 watts, but it never delivered such full rich bass like I am getting now. I will eventually buy another one identical to this one. I will also be replacing all my other speakers with Polk speakers. I am definitely sold on Polk Audio equipment.

Great sound, really brings movies and music to life!



Fancy modern body with clean boom

Jeffrey from Seattle, WA on 4/17/2018

Crutchfield Customer Review (What's this?)

I am very happy with my HTS 12. The black finish matches the finish on my Polk center speaker. The build and appearance of the HTS 12 is fantastic. Very clean bass. My main use of it is for movies, and this sub brings the experience to a whole new level. After calibrating with my Denon receiver, medium subwoofer volume control is perfect for movies. It is very loud and I don't have to crank up the subwoofer volume control. Highly recommended.

Pros: Great Sound Great Quality Chassis

Sounds good and the price is not bad considering what you get with this package. I am still tweaking this into a second system in a finished basement.

Pros: Good tight bass.Very pleasant to look at tucked in a corner.

Cons: Too big to hide from the wife

Makes my TSx550t's sound even better!

Pros: Sound and appearance compliments towers and decor; easy to install.

Cons: Prefer cherry to Walnut finish.

Tried them, liked them

Crutchfield Customer Review (What's this?)

I replaced my old Polk ported subs with two of these. They are cleaner sounding than the old ones. No "boominess" to them at all. Just clean and clear. I run duals all the time and they are shared between my Onkyo (for the home theatre) and my Nad M2, along with the Paradigm 100's for music. They sound great with both.The room they are in is a large room with vaulted ceilings, hardwood floors, half walls and large glass windows everywhere - an acoustic nightmare- and they fill the room just fine. I don't miss a single note. And they look good too! I was looking at some higher end ported subs, but due to the room configuration (and wife) I needed something with a smaller footprint. These fit the bill and I am very happy that I made this choice.

Pros: Clean clear quality pounding bass. Oh yeah!

Cons: I had to turn the volume up a little higher than my old, less powerful Polks, but that is probably because the old ones ported out of the front.

Crutchfield Customer Review (What's this?)

Great product. I already have a set of Polk tower speakers and this sub picks up where they leave off. Greatly enhances the sound!!

Pros: Great finish, build quality, and of course, sound.

Cons: None so far!!


Michael from Indianapolis, IN on 3/6/2018

Crutchfield Customer Review (What's this?)

I love this sub. Completes my home theater in style and sound. Had it set way too high when I first hooked it up and it shook the walls. Heard no distortion just pounding bass. Love Polk signature series in look and function. Major upgrade from old onkyo theater in a box system. Highly recommend.

Pros: Beautiful, thumps, no distortion

Cons: Nothing yet, doubt I'll find anything in future.

Product Research


12" Polypropylene Dynamic Balance Woofer: The HTS 12 houses a front-firing 12" polypropylene long-throw woofer with rubber surround for deep, accurate bass. The woofer incorporates Polk's patented Dynamic Balance technology and is Klippel optimized to provide clean, clear bass, better linearity, lower distortion, and greater durability.

200W Class D Amplifier: The Polk HTS10 employs a 200 watt (RMS) / 400 watt (Peak) Class D amplifier for dynamic bass performance.

Power Port Technology: The Polk HTS 12 powered subwoofer utilizes floor-firing patented Power Port Technology for deeper bass response and reduced port noise. The Power Port floor-firing design smoothly transitions air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence, distortion, and port noise. At the port tuning frequency, Power Port equipped subwoofers have 3dB less port noise than similarly configured subwoofers without Power Port.

Non-Resonant Enclosure: The powered sub's strong, rigid, and acoustically inert curved enclosure reduces unwanted internal standing waves for less audible coloration. Its non-resonant Meddite MDF construction, with extra bracing and thick baffle, ensures a more lifelike sound.

Controls: Built-in controls for variable volume, low pass filter, and phase let you tune in optimum bass levels. All controls are found on the rear-panel of the powered sub.

  • Volume: The rotary volume knob adjusts the volume of the powered sub relative to the other speakers in the system.
  • Low-Pass Filter: The variable low-pass filter is adjustable from 40-160 Hz. The low-pass filter is only active for the powered sub's stereo RCA inputs. The low-pass filter is deactivated when using the powered sub's LFE input.
  • Phase: The phase switch allows you to select 0-degrees (normal) or 180-degrees (reverse). If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass attack.

Line-Level Inputs: The Polk HTS 12 powered subwoofer is outfitted with an unfiltered LFE input and filtered stereo RCA inputs (subwoofer cable not included).

  • LFE Input (Unfiltered): The LFE input consists of an unfiltered mono-RCA jack (the LFE input bypasses the powered sub's variable low pass filter). Using the LFE input when connecting to an AV receiver or integrated amp with a filtered LFE output and built-in crossover control.
  • Stereo RCA Input (Filtered): The Stereo input consists of a left & right RCA jack (both jacks are filtered). Use the Stereo input when connecting to a receiver or integrated amp that does not have an LFE output, but does provide a preamp output.

Auto & DC Power On/Off: The powered subwoofer will automatically turn on when an audio signal is received and off when there is no audio signal for about 20 minutes. There is also a 12V trigger input on the back of powered sub which allows it to power on with your receiver or integrated amp that features a 12V trigger output (the 12V trigger provides a faster auto on/off).

Note: There is a switch on the back of the powered sub that indicates which power on/off method you will be using - Auto or DC.

Placement: You may place the powered subwoofer anywhere in your room, but it will perform best when it's on the same side of the room as your system's front speakers. Also, placing the subwoofer near a wall or in a corner will increase its loudness.

Frequency Response: The overall frequency response for the subwoofer is 22-180Hz, and the -3 dB frequency response is 28-120Hz.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I've always liked Polk and this sub is to match the one I already have and to "balance" the room. (-: [ Kirk  Jun 18, 2018 ]
Looks like the best deal for size and sound [ Michael  May 05, 2018 ]
Tried the smaller Polk subwoofer and didn't like it. After talking to Oliver at Crutchfield, this one sounded like the right choice. [ Shari  Apr 19, 2018 ]
I was actually looking for a Yamaha subwoofer to replace the one that recently failed on me. However, the choices for that brand seem to be limited. I've heard that Polk is a very good brand for audio equipment and with all eleven reviews being 5 star, this particular sub seemed to be a good choice. I'm very excited to receive this product and hear what quality of low frequencies it delivers. [ Steve  Apr 05, 2018 ]
Saved money on this sub via your scratch and dent pricing. Also it seem to be pretty good unit according to others who purchased it. [ Marc A.  Mar 14, 2018 ]
great comments [ Raymundo  Mar 11, 2018 ]
I want an upgrade on my Home Theatre System. [ Reggie  Jan 29, 2018 ]
After comparing subs I decided it to be for my system. [ Randall  Jun 16, 2018 ]
Have Polk center speaker. Crutchfield has nice shopping site. [ Manuel  Mar 29, 2018 ]
I have a Polk subwoofer that has lasted forever, but I am using two mismatched subs right now and I would like a matching pair. I am using them in a large area and I needed them to be ported. These fit the bill. [ Tech head  Mar 07, 2018 ]
I currently have Polk center, front and surround speakers and their performance has been outstanding. Based on my experience and the new design I chose the Polk HTS 12 to complete my surround system. [ Thomas  Jan 10, 2018 ]
#1- It is a work of art and should work perfectly with my Polk signature series speakers #2- I bought 2 S60 towers, bundled with the S35 center, Onkyo TX-NR777, and lastly the elephant in the room- The Polk PSW125. What a massive sub! You would think the elephant would mix in well with the signature series, but honestly the different cone material makes it stick out from the herd. The crisp, accurate and exceptional response is just not there (Comparatively). [ Zachary  Dec 02, 2017 ]

2 questions already asked

Mine does the same thing. When I push it to hard it stops playing and I have the red flashing light from the rear. I had the gain to high on back of sub. I cut it down just a bit and all has been good. [ Cameron  Apr 16, 2018 ]
I'm sorry, but I have not experienced this problem. In fact my unit has performed quite well. [ Thomas  Apr 16, 2018 ]
We added two 2x4 boards to lift it off of the floor and we have never had any problem. I would recommend trying it to see if perhaps the heating up is happening. My neighbor plays in a band professionally and recommended it. [ Deidre  Apr 16, 2018 ]
separate cord that plugs into the back of unit [ eddie  Feb 26, 2018 ]
It plugs directly into the unit. [ Thomas  Feb 26, 2018 ]
Plugs in [ Aaron  Feb 26, 2018 ]
the power cord plugs into the unit and into the wall at the other end fantastic speaker -very very happy with it [ greg  Feb 26, 2018 ]
The power cord plugs into the unit. It is not hard-wired. [ DAVID  Feb 26, 2018 ]
It plugs into the back [ Cameron  Feb 26, 2018 ]
No, it is a separate cord. [ wesley  Feb 26, 2018 ]
It has it's own cord that plugs in and can be removed [ ronald  Feb 26, 2018 ]
