I picked up both of these subs to compare since they were (are) on sale from best buy. The PA HD15s was 450 off and the Klipsh KW100 was 350 off (or there abouts). I have been playing around with both trying to determine which to keep.
The PA 15s is a 15" with 35-150hz response @ 250watt. The Klipsh is 10" is 22-225hz @ 225watt. Obviously the 15" has more oomph but the 10" is nice because it is smaller and fits more easily in different places. The klipsch obviously dig a bit deeper but how much a difference is that extra 10hz for movies? 50/50 music / movie use in this environment. I have no real intention of keeping more then just one of them. Although the 15 definitely puts out a lot more bass I am not sure if its worth keeping over the smaller and more managable (size wise) 10".
This has been tested through both a vsx-1027k and avs-1713
Would really appreciate some feedback and opinions on what long term benefits I might see that would sway me one way or another. I know they are not great, but they are what my budget allows.
