Bests & Worsts Reviews from Amazon

For the longest time I was trying to decide between the PSW10 and the PSW505. The PSW505, on sale, was about twice as much as the PSW10 and offered much better specifications, both on paper and in real world testing. What I always debated, though, was if I really needed the oomph of the PSW505 and if I did, would I also be willing to live with the larger size. Like always, I let my frugal side win and opted for the PSW10. Once it arrived, I swapped out my old Logitech Z2300 subwoofer (which, in all honesty, wasn't that bad to begin with) and began to listen. Instantly, I was disappointed. The port noise under 40hz was absolutely terrible at medium to high volumes. I always thought that since the frequency range cut off fairly high, port noise wouldn't be a problem, but boy, was I wrong. Anytime whatever was playing dipped under 40hz, I was met with farting, burping, and fluffing air sounds that instantly put me off. I never had that issue with the Z2300; they just didn't play at all. So, disappointed, I ordered the PSW505. When it arrived, I was surprised that the size difference was minimal. Sure, it was bigger than the PSW10, but only an inch or two (see related pictures). When I turned hooked it up and turned it on, I was instantly amazed. Everything sounded great, and, more importantly, frequencies below 40hz not only played, but there was zero port noise. I haven't tested it lower than 28hz, but that's all I really wanted to play down to, anyway. All in all, I'm glad I decided to go with the PSW505. It may be slightly bigger than the PSW10, but it's much more than slightly better sounding. Hooray for finally getting to hear everything, and maybe even feel a bit of that ultra low range (>28hz), too. Note: The grill did arrive smashed up on the PSW505 due to the bad packaging on Polk's part, but a quick call to them got them to send a replacement free of charge.
