+1 pesky, elliott, realthing - It has to do with the control of the woofer, higher damping factor is a major player in this. It does not have to do with how low a frequency the amp/driver will produce. If you want the deepest bass, it comes from a SS amplifier as tube amps just don't go down ultra-low. The limitation in deep bass is the output transformers in most tube amps. The only exception I've heard is David Berning tube amplifiers, with no output transformer. Have fun!
What is Tight Bass?
I’m confused. Speaker size with a large woofer…can it be tight?
is it about efficiency? Amp power? Electrostatic?
