RE: Lowther Speakers

If you're listening to high quality recordings that have peaks 20 dB above the average, the ability to hit 105 dB (ignoring the effects of thermal compression) implies an average SPL of 85 dB. Whether or not that's enough is a matter of personal taste.

If you want 90 dB with no loss of impact on the peaks, imo that implies at least another 20 dB of amplifier output and another 30 dB of RMS or AES (not "music program", not "peak") power handling from your speakers. So with 30 watts of amplification, we'd be looking at a minimum of 96 dB efficiency for the speakers, and about 250 watts RMS power handling to avoid compression (less power handling required as the efficiency goes up).

(I'm using the word "compression" when "thermal modulation" is probably more technically correct.)

Now there's a lot more to delivering pain-free 110 dB peaks than just the raw numbers, but that's a starting point.

Imo, ime, ymmv, etc.

Me being a dealer makes you leery?? It gets worse... I'm a manufacturer too.
