The first thing is to work out what the problem is. I have a quite small listening room 4.5 x 3.2 metres. Bass control is my issue not lack of bass, the walls shake and items on walls rattle even at moderate volumes. Adding 2 subwoofers has allowed me to even out the bass response whilst using a miniDSP to correct for room modes. The difference is startling. It also enables be to restrict the bass output of my tube hybrid power amp. This works in class A up to 10 watts, removing bass from the amp and speakers below 60Hz means I'm always in class A.
