Power amp sensitivity.......

The 2150B is 1.5v and the impedence is 10K. Can't help on the others.

Krell ksa-150 is 1.7v with 47K impedance.

Thanks guy's for your help!

I hope this triggers some responses (if not I will start a new thread)..

My top end amp ASL Hurricanes has a high sensitivity. Therefore it plays loader then my bass amp. The Hurricane is powering the midrange and tweeter section of my RS 1-B's. The bass amp (for now) is a Perreaux 2150. Because this has a lower sensitivity I have to raise the volume on the crossover for the output of the bass. Is there a better way to do this? In other words I would like to lower the sensitivity of the ASL's to compensate for the woofer amp.

You might try exploring in line attenuators - there are fixed value ones and varible ones (like passive pre amps). Frankly though I can't see the down side to adjusting the volume of the 2150. Thats the normal way when you don't have identical amps.
