difference between 90 rms and 150 rms
hi, i am thinking of redoing my speakers and right now they are running off of 90 rms and i want to up the watts to around 150 because i want louder from my speakers. and i am wondering how big of difference is 150 from 90.

Re: difference between 90 rms and 150 rms
10*log(150/90) = 2.2 dB
more power is for headroom, not really loudness the best way to get more volume is to find more efficent speakers. What is the efficiency of your current mid/tweets ?
