Monoblocks did not work

Thanks for the clarification. What i wanted to say and what i said somehow didn't "jive". No more typing under medication for me... : ) Sean

How are you running these amps ? Bi-amped ( vertical or horizontal ) or bridged ??? From the input that you've stated about power output per channel, i'm assuming bridged.

For sake of clarity and those that may not know the different terms, vertical biamping uses one stereo amp per speaker. Channel A runs the bass section of the speaker and channel B runs the mids and highs.

Horizontal uses one channel of each amp for the bass and the two channels of the other amp feed the highs.

Bridging takes the two channels of a stereo amp and converts them into one BIG channel. You then need two amps in order to make a stereo pair.

All three of these arrangements sound different even though your using two identical amps. Bridging typically gives the highest voltage levels possible out of the three different arrangements but usually results in a much harder and thinner sound. Sean

Skip the bridging and go straight to bi-amping. While active biamplification is best, you can still get some gain by doing this passively. As you've noticed, most amps do not sound good when bridged. Sean
