AMPLIFIERS: Solid-State
Solid-state amps with their inherent higher-damping are uniquely
suited to control the higher-mass of real woofers (10" & greater).
If you love tubes, bi-amp with tubes on top, solid-state on bottom.

* AllegroSound electronics are never hard-started,
ensuring maximum life from the electrolytic caps,
and not run with excessive bias and resulting heat
that damages caps, resistors, transistors, ic's, tubes
and solder connections. Hard-starting & heat kills!!!
