RE: Tri-amping T IV-A's with tubes?

Posted by josh358 on December 3, 2024 at 13:11:50:
The whole speaker is inefficient. The IVA manual claims that 200 watts will driven them to 110 dB SPL at the listener's seat.

Bass, as you suggest, typically requires the most power, followed by midrange (though it isn't that much lower), with the tweeter needing much less. I'd probably split the difference and go with equal power for the bass and mid/tweet combo.

My personal preference is for lots of headroom, IMO, a solid-state amp should never clip -- the limit should be set by the speakers and their fuses and your ears.
