Need help What monoblock power amps for bass?


I own a pair of Silverline Sinfonia speakers.These are very large speakers (over 240 lbs. each),96 dB and 8 ohm stable.Very aesy load for any amp,so power is not mandatory,anything over 50W/ch is OK..
They are tri-ampable.I am looking for opinions on what monoblock amps to use for bass drivers ONLY.Each Sinfonia has two 12" woofers and one 7" woofer.7" driver also contributes to midrange,so this is the trickiest part of my amplification story.I don't want mellow and soft bass,but don't want cold vocals either.
I plan to use either tube or SS monos and limit them whit a potentiometer in order to achieve a tonal balance with midrange and tweeter.Midrange and tweeter will be powered with 320B XLS SET monos (30W/ch).
The areas i am looking for in bass are - slam,speed,definition and ambience.I like fast and tight bass (often connected with SS amps),that is a priority.
Any suggestions will be very welcomed.

This will be largely determined by the speaker. I am not familiar with your speaker but it depends how they are designed. Q=0.71 is critically damped and will sound "tight" in the bass. Anything above a Q of 1 starts to sound pretty muddy.

Bass is two things - loudness and length of notes. A powerful bass can be achieved through longer notes and less decay (underdamped) a lean or tighter bass will be created with criticial or overdamping. In our modern world of impressive bass, often some bass tightness has been traded off to achieve deep satisfying bass extension - but you will hear the effect on a well recorded acoustic kick drum (such as Sheffield Labs Track 1 of their drum track album).

SS will certainly be tighter than an amp with a high output impedance but a lot will still depend on the speaker design.
