I've determined that at 3.65 (12 feet) from my mains (with 86 dB sensitivity 1W/1M), using 3dB headroom, I can get 90 DB SPL with 67 Watts.
(I'm considering the HK 525 which is 70 Watts)
Is 90dB enough? I know 105 is reference... Does 90dB blow your head off or is it not loud enough?
Also, do I really need to include the 3dB for headroom? Looking at it another way, is the 105 dB reference a MAX and therefore the 3dB headroom is unnecessary?
Thanks!
