    right now i have an avatar b210(8ohm) and im thinking about buying some sort of avatar cab so i could use the biamp function on my head(100w. @ 8ohm and 300w. @4ohm). so i was curious if putting 100 watts into my 210 would be too little power for it. has anyone tried this, if so did if sound good?

    DJP, 100 watts is plenty. I have the 800RB + B210 + B212 and it sounds amazing! If you get a 4 ohm version of the B212, you're pumping out a total of 400 watts out of the GK and it ROX in bi-amp mode!

    I had a similar conversation with Dave at Avatar when I bought my 210 from him on Monday. He says they are highly sensitive speakers that do well with low power, even though they're rated to handle a ton. My question, though, was if 170W was too little. Did you see the Avatar 15 up for auction below? Might go nice with the 210. It doesn't have a horn so it would make for a good woofer in a bi-amp situation. Only 36 lbs!

    By the way, I'm guessing the "300W @ 4 Ohms" you typed above was a typo. 200W maybe? Otherwise, you'll be sending 150W into each cab.

    In the early 1990s, I used to run an 800rb into two 15" cabs for lows and one 1X12" + horn for mids & highs.

    If you're biamping, and crossing over at say 500 to 1K like most (I used to use 750), you're only running mids and highs into your 2X10" cab. 100 watts is plenty power for that. It should work fine, if you're going for the biamp set up.

    If you are going to go full range, 100 watts is probably underpowering a 2X10" cab.

    brock...the 800 rb has two internal power amps...in the biamp mode, the lows go through an amp rated 300 watts @ 4 ohms (200 watts @ 8 ohms) and the highs go through an amp rated 100 watts @ 8 ohms. Don Juan's numbers were correct.

    The Avatar Compact 15 is a great cabinet but might not give the lows one needs. I don't have experience with a Delta 15LF loaded one though, only Kappa 15.
