Polk Audio HTS 12
Powered subwoofer (Washed Black Walnut)
Our take on the Polk Audio HTS 12 by Crutchfield's Kramer Crane
Mark "movie night" as a special event on your calendar
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.
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.

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.

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 ]
Brand name, excellent reviews, sale price. [ James Jul 28, 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
3 answers Why do I get a red flashing light from the power indicator after several hours of play in the auto sensor position? If I unplug the sub-woofer, it does regain its' power and plays without a hitch. No heat build up that is obvious. There seems to me that the unit is not receiving a signal? Does anyone have any thoughts? I will contact Crutchfield and /or Polk for further details for follow up. [ Gunny Apr 16, 2018 ]
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 ]
