Bi-amping

Y-connects?

Passive Biamp, input to the amps from the preamp. That's my take on it.

Really?
But without some kind of crossover, either at preamp levels (or at power amp levels)
that technique would feed full bandwidth sound to the woofer's amp and then to the woofer ...

That pretty much defeats the point of biamping, doesn't it?

You really want some kind of Low pass filter on the feed to the woofer amp ...
and a high pass to the 2nd amp and then to the tweeter (or the upper drivers if its a 3 or 4 way) ...

first, the speaker has to be designed for passive biamping (or modified).
second, you lose -some- of the benefits of biamping, but not all (and it's much easier to care for and feed). I spent a lot of time describing this earlier in this thread...

I read that - we both said that.
There basically has to be a crossover somewhere - either at power level (in the speaker, or external),
or done at the preamp stage, either active (like Ashly) or passive ...

You want to bandwidth limit what the drivers see somewhere.
Speakers designed for biamping still have a crossover - just one that splits when you remove the jumpers.

I just hope the OP is getting it.

Bringing up old thread to verify my situation...250TI w/tibq Charge coupled Xovers...passive Biamp capable and biamp so amp1 on L & R woofer and the amp2 on l & r "high end"..............as opposed to L of amp1 on low and r of amp1 on high and the same for amp2 on the other speaker

Thanks

If they are identical amps, putting 1 amp on Right spkr and another amp on Left spkr was how Rolf always said to do it.
He said the power supply had more headroom that way rather than one amp loaded with 2 woofers.

I did it the other way with my 4341s ...identical amps - 1 on high split drivers (L & R) another on low split woofers (L & R).

Another method is to use a high-power (usually class AB) amp for the woofers, and a low power (class A and/or tube) amp for horns.

[hjames]

I think Mark's idea is to use the existing amps that he already has ...
so its either horizontal biamping or vertical biamping with his current amps.

Well then...nevermind

They are R E A L L Y good amps ...
