I currently own a PSW505.
Im having issues playing it at loud volumes. When I do so the sub makes a very strange sound, like the cone is moving (like i can hear it physically moving).
Whats wrong? Also what sub would you reccomend as a suitable replacement in case it calls for it? I would like to spend under 500 for a used one.
I'm not sure but it sounds like you are running too much power and the speaker is bottoming out.
too much movement and passing it's x-max.
sure every body like loud sub sounds with a higher volume, but you can over do it.
At under $300, many individuals in this forum recommend the BIC PL-200.
If you can get a good price, then consider a second 505. The 505 will not play quite as low as the PL-200.
At around $400, individuals like the Hsu STF-2 that is considered a step-up from the PL-200. The Hsu will be much more musical than the PL-200 (you need to read the PL-200 thread for comments from former PL-200 owners who have upgraded to the STF-2).

Ricci also like the Premier Acoustic (~$400) which will play quite loud but has most of its frequency response above 35 Hz.
