Our take on the Polk Audio CSW100

by Amanda P.
Polk Audio

It's easy to see why Polk Audio's décor-friendly CSW100 won the prestigious 2006 Innovations Design and Engineering Award from the Consumer Electronics Association. This subwoofer's clever construction allows for out-of-sight placement in your floor, ceiling, or even a piece of furniture. After it's installed, all you'll see is the included 4" x 14" grille, which looks like an ordinary air vent.

Performance is excellent, too. You get clear, potent bass with movies and music. Feel the deep rumble of the engines in an on-screen car chase, and enjoy richer, fuller sound from your favorite songs.

Polk's optional SWA500 amplifier powers the CSW100.

Features

Matched Amplifier: The CSW100 requires and is designed to only be used with the Polk SWA500 Subwoofer amplifier (107SWA500, sold separately). The SWA500 comes with a SPEX Card that configures the EQ, crossover, and power control circuitry to match the CSW100 subwoofer.

Woofer: The CSW100 features a long-throw 10" fiber cone woofer with a rubber surround.

Enclosure Construction: The CSW100 has rigidly braced MDF enclosure construction for low resonance and rattle-free performance.

Slot Vent: The enclosure features an integrated slot vent for deep, driving bass.

Grille: The CSW100 is designed to fire through an opening in the floor or ceiling. Once the installation is complete, the opening can be covered with an optional grille. The CSW100 comes with a 4.5" x 14 " grille that looks like an air vent.

Spring Posts: The CSW100 subwoofer has one set of spring post terminals that will accept pin connectors and bare wire.

Mounting Options

Mounting Location: The CSW100 is designed to be mounted between floor or ceiling joists. The CSW100 can fit between the tighter joist-spacing of QuietFloor or wooden I-Beam construction. The subwoofer requires a joist spacing of at least 13" and a depth of 9". The overall length of the subwoofer is 26.25".

Mounting Brackets: The supplied brackets and wood screws allow you to mount the CSW100 to any parallel floor or ceiling joists.

Isolation Pads: When the enclosure is installed, it fits snugly against one of the floor or ceiling joists. To prevent rattling, two of the isolation pads should be installed between the enclosure and the joist, while the other three isolation pads should be placed on the front panel of the enclosure.

Outstanding in-floor sub

Written By Wt61443, Linden, NC on Saturday, April 19, 2014
Crutchfield Customer Review (What's this?)
 
I'm a big Polk fan. In fact most of my upcoming house build will feature Polk products (in-wall, in-ceiling speakers, and in-floor and in-wall subs). I am installing 4 for these in-floor subs in my great room powered by 2 Polk SWA500's (designed to match up w/these subs). While I haven't installed these subs yet (house is still under construction), I have listened to them simply outside of the shipping box and they perform great (in my current home). I have demoed them on both music and movies and there output is very nice. Stats say they play down to around 30hz and to my untrained ear that seems accurate. If you need an in-wall or in-floor sub that plays lower I would suggest looking at other alternatives. Most movies and music will sound great on them though. I have another manufacturer that I will be using for my dedicated home theater room (6 15's!!!). The fact that you can hide the sub under the flooring and all you see is a small grille, these subs are hard to beat.
Pros:
performance, out of sight sub
Cons:
under 30 hz material, pricey when you consider the cost of the sub and amp compared to a "normal" sub, but then again it would take up floor space.
