Polk PSW111 - Quieter than expected bass when volume is low
I originally had an Infinity speaker set, but my sub died. I recently purchased a PSW111 to replace the sub, but am not happy with the bass level when the receiver volume is low (e.g. when watching a TV show at a normal volume level). I have the sub set to auto for power, and sometimes it doesn't even turn on (unless I turn up the volume or if the TV theme music comes on). Even when it does turn on, the bass level seems to be pretty low. Sometimes it turns off in the middle of a show.
I followed the instructions and set the other speakers to "small". I did not change any of the other default settings. I'm using the LFE connection. I did not have this problem with the Infinity subwoofer. I think the Infinity was a 10", but I didn't think there would be such a difference, especially after all the reviews I read.
I placed it about 8 feet away from the receiver, probably a foot or two from the corner of the room. The cable I'm using is a low quality RCA cable, probably around 15" (I was planning on replacing this with a monoprice cable soon). I used to have the Infinity sub right behind the TV connected with a 6" RCA cable (probably not a good idea to have it so close to the TV and other equipment).
Please note that when the volume is loud, the subwoofer is pretty impressive. It doesn't shake the house, but it does fill the sound well and is very clean.
I decided on the PSW111 based on the great reviews, the size, plus my needs (I don't need house shaking bass). However, I expected a little more when the volume is lower. Could I be doing something wrong, or is this how the sub performs on a lower volume setting?
