Onkyo Cable Amplifier

Experience deep, thunderous bass with the Polk DSW PRO 500. It sports a 10-inch woofer driven by an efficient 200-watt amplifier. This advanced subwoofer features Polk's exclusive Feed Forward(TM) technology, which reduces audible distortion without limiting volume. You get quick, precise response throughout the sub's entire frequency range, even at ground-shaking volume levels. The PRO 500 also includes the Polk Room Optimizer(TM), 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 sub's 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. Removable feet let you position the PRO 500 for either front-firing or down-firing operation, whichever you prefer. The all-new DSW PRO Series represents more than a significant step forward in subwoofer performance. Rather, with the incorporation of two proprietary Polk Audio technologies that offer clearly discernable benefits, you might want to think of the new DSW PRO Series as representing a new subwoofer performance standard.

Initially I bought a Polk PSW10 sub to compliment my Monitor 50 floorstanding speakers, which are great but with only dual 5 1/4 woofers, the 50's are lacking in the bass department. The PSW10 was decent, but I was still missing the deep hard hitting bass I had hoped for. The DSWPro 500 took care of that and then some. I'll start with the fit and finish. This sub is very well built and attractive to look at even though it is all black. The base feet are solid and not cheap like the monitor series speakers or the little nubbins on the PSW10. If you want, you can move the feet to the back side to make it a front firing sub. The speaker is very clean looking and the side port is attractive. In the down firing position, the blue LED light looks very nice and if you don't like the brightness of it, you can turn the light off altogether. Features and Sound This sub has very nice features. There are the normal volume and crossover knobs in the back, but what makes this such a cool sub is that it comes with a remote with volume control and equalized settings depending on where in your room the sub is placed. Anything you need done with the sub can be controlled with the remote. As I mentioned before, the LED light looks cool and the fact that you can turn it off is a nice touch. This sub sounds ridiculous. Some nights I am actually afraid to turn the volume up too loud because this thing shakes the whole house. The bass is tight and clear. When I first bought it, the sound was muddy, but I hadn't set up my receiver crossover settings yet. Don't forget to do that. I bought this sub for a ridiculously low price of $269... but it was refurbished. Absolutely nothing was wrong with it though. It was like it was brand new. I see that it is selling new for $500, but maybe if you are lucky, you can find it refurbished for the same price I paid. Worth every penny. 16 of 18 people found the following review helpful. Superb Low Frequency Enhancer (LFE) sub $1k. By George Denver I like down firing subwoofers with a front / down firing port for the following reasons:1) It's easily invisible in any system when crossed below 80hz. 2) Placement near rear walls is not as critical or demanding as rear ported subwoofer designs in smaller rooms can get. 3) Cloth grills on a front firing subwoofer is a pain. It will eventually attract a lot of dust, silverfish or children, & that adds to U'r system maintenance in the long run.Background:I was using the Onkyo SKW-150X subwoofer previously & it was the weak link in my HT system in Zone 1. The Onkyo subwoofer had a down firing 8 inch woofer with a front port. Placement was easy with that subwoofer but with a less than 100w continuous power built-in amplifier, it struggled to even touch the rated 30hz & I c'd feel it every time I watched an action packed movie. I sold it on ebay & started to look out for a new subwoofer. Being a budget audiophile, I wanted a 10 inch subwoofer under USD600, with a down firing design & possibly no port at the rear.Down firing subwoofer designs are very common these days. Paradigm, Klipsch etc, to name a few, have very good down firing subwoofers. Unfortunately they all have rear ports, mostly to avoid port noise. Given my demands, I was left with only one choice - Polk Audio DSW PRO 500. The PRO 400 with 8 inch woofer was too small & the PRO 600 with 12 inch woofer was too big for my 15X14 living / media room.The good:1) Big bad bass that does not even distort at insane levels. I live in a 8 storied building & this thing is powerful enough to get complaints from the neighbors. Lol. 2) Down firing 10 inch woofer & down firing slot port with 200w continuous power. Good enough for a small / medium sized rooms. For bigger rooms, buying two DSW PRO 500s instead of one DSW PRO 600 (12 inch woofer) sh'd give
