Classe CAV-150 with Klipsch RF-7

Hummm. Again, I didn't know that would work, since BOTH THE UPPER AND LOWER terminals went through the crossover! If you were using an external crossover, then amplification, I could see using different power to the terminals. Ok...

I am using 2 bridged channels to each woofers (300 watts) and 1 channel to the tweeters (150 watts) CAV-150 has 6 channels 150 watts per channel.

Explain more how you are "bi-amping" with different power to the woofers and tweeters please! I mean, after all, you are going through the crossover with those two pairs of binding posts, yes? Actually, I didn't now those speakers had dual posts.
Are you bypassing the internal crossover? If not, I pressumed you needed the same power to the top posts as the bottom, as they were connected to the crossover, either way. It's late, and maybe my thinking is wrong

Classe CA3200 , 200w into 3 channels .
