You could be sitting in a null. A larger sub will still have the null. Also, move the sub around. Including into the corner.
Try the sub right behind your seat.
Small rooms can be problamatic.
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.
