Polk Audio DSW Pro 660wi Powered 12 Subwoofer, 400W, Black This listing is for a carefully used Polk Audio DSW Pro 660wi subwoofer. This powered sub is rated at 400W RMS (with its own internal Class D amplifier), and utilizes a single, down-firing 12 woofer. The rubber feet can also be repositioned so that the sub will front-fire. This unit has some minor surface scratches on the top (see pictures) - however it still works perfectly. Comes with all accessories shown in pics - the small remote to control options like volume and phase, plus the AC power cable. You will need to supply your own single RCA cables to hook this up to your receiver / amp dependent upon your desired configuration. Please note that while this sub is wireless ready, it requires an additional Polk accessory to be used in this fashion that is not included - I only ever used it with traditional wiring to my AVR. Manual is not included, but you can find it online on the Polk website. This was used at reasonable volumes over the course of its life and is still in excellent working order. I am only selling it because I recently upgraded to a higher end sub. This will ship via USPS anywhere in the continental US. If you are in the Boston area, we can also arrange for local pickup, which will end up saving both parties some money. Sales are final; no cancellations, no returns. Please be aware of that before clicking Buy. If you have concerns about the items condition, please feel free to ask me any questions, or you can request additional photos of something specific. This item is in perfect working order - it was literally hooked up to my system just a few days ago until it was replaced with a new, more expensive sub. Thanks for checking out my listing, please let me know if you have any questions. I have pasted in the full product listing below for reference which highlights all of this subs features (and there are a lot.) This was Polks flagship model, and its an excellent sub. Its especially great with the super deep bass effects found in blockbuster movies, but it also adds snappy punch to music with a lot of low end. Priced to move. This is a big sub - approx. 17 cubed, and weighing 45 lbs. Make sure you have space for this monster. Deep bass you can hear and feel Rumbling spaceships, thunderous explosions, the smooth, sonorous tones of a double bass — Polks DSW PRO 660wi can handle just about anything you throw at it with power and precision. It features a 12 woofer driven by a potent 400-watt amplifier, capable of filling even a large room with deep, rock-solid lows. This authoritative sub uses Polks exclusive Feed Forward™ technology to reduce audible distortion without limiting volume. You get quick, precise response throughout the subs entire frequency range, even at room-shaking volume levels. Sounds great no matter where you place it The PRO 660wi also includes the Polk Room Optimizer™, an ingenious feature that lets you specify the location of your sub with one of four options — corner, mid-wall, in-cabinet, or mid-room. The Optimizer then automatically equalizes the subs response to ensure smooth, clean bass from that position. You can easily access this function, as well as the volume control and phase switch, with the included remote, so you can fine-tune the bass from your favorite listening spot. Removable feet let you position the PRO 660wi for either front-firing or down-firing operation, whichever you prefer.
