+1 on the Rythmik F12G. I have one (one) myself and it's a great sub for music. I have a dual system connected to it (home theater plus a 2.1 music system) and it excels in both applications. I have no problem getting superbly musical, tight bass from it. It's highly adjustable to that end (but does not have a DSP app associated with it - you'll have to do it manually) and digs deep. Can't recommend this particular sub enough.
Gain level on a REL sub
Hi. I have purchase a REL R 218 sub to compliment my system and as far as sounding musical, I am happy. However, the gain is almost all the way up and I don feel that punch and slam I am looking for. Musically I am impressed with it but I still dont feel that level of impression overall. When I had the HSU STF-2, it was in a different league with in terms of impact and punch but for detail, the REL was better. My question now, Do you think I should try getting a another REL with the same model for a stereo pair or go with a different sub? My room is pretty small but it is treated with acoustic panels.
