I have some experience with teses speakers. The bass section needs alot of current. We tried a set with a Bryston 3b..not enough power. The amp kept clipping. Then we tried the 4B and it was excellent.
The 4B will control the bass with your speakers It has the power current and damping factor. Make sure the surrounds on your woofers are not dried out. That will change the compliance and muddy the bass.
