al111 and amps

I have 2 tfm 24's and 1 tfm 35.Should i run the 2 24.s bi amped ( which are vertically bi amped now) or run the 35 to the ribbons and a 24 to the low end.If I go with the last idea will I have a problem with controlling volume levels because of two different amps.


Thanks

Or maybe the 35 to the ribbons and bridge each 24 to each woofer...

Right if the woofers are 4 ohm then you can't bridge the 24's

Re: al111 and amps

the ribbons need far more power than the woofer section in the ALIIIs.
run the -35 stereo and try one -24 per woofer.
ALIIIs are 6R nominal...cant recall exact resistance on woofer section and my meter is at work....if i remember ill bring it home and check tomorrow.
or..just keep an eye on the meters/ temp. and you should be fine.
.....a VULGAR DISPLAY OF POWER.

The AL-IIIs are a HARD 4-ohm load....ribbons more difficult than the woofers...

Ribbons are 4 Ohms almost entirely resistive.
