Polk Audio have really been pushing out the boat over the last few years in terms of providing quality hifi speakers at very reasonable prices, if you are currently looking at a new entry level subwoofer then one of the current best deals doing the rounds is most definitely the Polk Audio PSW10 Monitor Series a 10-Inch Powered Subwoofer the PSW10 looks good and has performance that far outstrips its price.
Now despite being specified at a meagre 50w RMS this 10″ speaker is actually very capable and gives great bass reinforcement at very reasonable volume levels. The 50w RMS tag is a bit misleading an in actuality this unit sounds great and is very capable of keeping up with units rated far higher in terms of basic specs. The PSW10 is built around a basic 10-inch polymer-composite cone driver this is in turn supplemented with Polks Klippel measurement technology a laser system meant to center coil inside the magnetic field for a better and more accurate output. To be fair at extremely high volumes the sub does introduce a little distortion to the very lowest end of a signal but this is to be expected at a unit in this price range. So this unit is probably best used in smaller room configurations, so if your living room is like a cathedral perhaps you should spring for something a little more top end like the PSW505 or similar. Anyway this minor problem is pretty much un-noticeable in day to day operation and the PSW10 reproduced the bass end on our tested recordings with aplomb, keeping things deep but also controlled sounding the PSW10 also handled the central low end on bluray soundtracks with ease.
All in all you could do far worse than the Polk Audio PSW10 for subwoofer duties in an entry level system, and at Current prices its a bit of a steal. Especially if you are generally working in a small to medium room and at moderate volumes. Well worth a listen.
