I think Trelja pretty much hits all of the points. Especially the power issues and the impedence matching ones as well. If your amp is biased properly (and this is very important) and you still have poor bass response, you may have to just consider getting either more suitible speakers or a different amp. I've had more success in the bass department as well as FR linearity, using amps utilizing the 6550/KT88/KT90 family of tubes.
