How much clean headroom would I get going from a 25 watt WGS 12" Green Beret speaker at 99.6 sensitivity to an 50 watt Eminence GB128 speaker with a sensitivity rating of 101.3. Also the Green Beret is too dark sounding. The amps is approx. 22 watts.

101.3dB - 99.6dB = 1.7dB "more headroom."

10^(1.7dB/10) = ~1.48x, so roughly like your amp has ~50% more power. However, it takes about 10x more power (a 10dB change) to get the sonic impression of "twice as loud."

I'm glad I changed the speaker to the Emi GB128. So many benefits it's louder cleaner not as dark as the Green Beret. I also changed the JJ6V6's to an EH 6V6GT & RCA 6V6GT that bias up to the same ma.
