- Real wood veneer finish.
- Slot Load Venting improves bass response. The wide, long Slot Load Vent dramatically lessens turbulence, noise and distortion, pouring out a tidal wave of precise, thunderous bass!
- Big 12 inch Long Throw Driver for longer excursion and better linearit.
- High current 300 Watts Continuous (460 Watts Dynamic) power amplifier.
- Pro-grade 5-way binding posts speaker inputs and outputs.
- Magnetically shielded for safe, flexible placement next to a TV or video monitor.
Pretty decent

This review is from: Polk Audio PSW Series PSW505 12" Powered Subwoofer Single
Pros:
About 5 years old and still going
Pretty loud in a room the size of a 1 car garage
Cons:
As other reviewers have stated, it is loose and boomy sounding
Port noise can be horribly loud at certain frequencies
Fuse inexplicably blew after the first year
Volume/crossover knobs need cleaned, they developed noise when turning
Auto-clipping attenuation gets on my nerves (personal opinion, others love it) but in my experience it just forces you to always adjust gains/volumes per media if you're listening at high volumes
Overall Review:
I am reviewing this sub for my brother. It has basically been through hell and back and is still chugging along. The sub was taken out and mounted backwards (It actually made quite a big difference in the 20-30hz range, and port noise isn't quite as bad), and it has even been temporarily used in a vehicle hooked up to a 500rms Pioneer amp (Yes it really pounds hard in a car)
The inside of the enclosure is pretty interesting and answered my question as to how a sub in such a small box can reach such low frequencies. The port, although tuned well, is too small for a subwoofer with such high xmax, which causes port turbulence (noise) when the sub reaches xmax.
While not an expert, I have designed, tuned, and built many subwoofer enclosures, none of which I've had any problems what-so-ever with port turbulence. I understand they want the sub to be small, but that doesn't mean they have to make the port so small. You CAN design a small box with sufficient port area to alleviate port turbulence and still stay within a reasonable tuning frequency with reasonably flat response.
Also, IMHO, not a fan of rear-firing ports. I've achieved the best results when the port fires the same direction as the woofer. IE: port and woofer firing into the corner will yield positive gains in output. With this sub, it's either the woofer or the port into the corner, not both, so output suffers somewhat. In the case of this sub, it's best to fire the port into the corner (just to help hide the port noise)
