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.

One of the best bass amps, and a great deal on the used market, would be from the Eagle/EKSC line. A pair of their 2 series (A, B, C) stereo amps or 400 monoblocs might be outstanding. They are fast, tight, and provide great woofer control while sounding musical without being dry and lifeless.
Ralph, regarding your comments on bi-amplified systems, have you ever heard
the Orion system designed by Sig Linkwitz? In its intended configuration a
separate amplifier channel is used for each of the four drivers per speaker
channel. This is with an electronic crossover.

The Orion system has a very large internet following and reading Mr. Linkwitz's
site I found his design objectives closely match my listening goals. However,
I've heard two different Orion systems and was disappointed in both. I expected
the individual amp/driver configuration would have been an advantage (low
distortion?). Now, from your comments, I wonder if this could have been a
detriment?
