Bi amping required active crossovers?

xecluded · 28th April 2011, 12:39 PM

or not. I've read somewhere on the web where people said it is very bad to have two separate amps drive woofers and tweeters individually feeding to a preamp without using active crossovers.

I plan to have one amp drives my JLB 2235H woofers passively crossing at 400hz and another amp drives my Altec 2440/horns feeding onto my Van Alstine preamp. Just want to ask the question before I ruin anything by doing it this way. Thanks.

If the tweeter/woofer have passive crossovers then there is no problem.

Hi,
there is confusion in the use of the term "Bi-amping".
Here in the UK we see that as using two amplifiers to feed the same signal to the two halves of a passive crossover speaker that has dual (or triple) input terminals.

Some countries (US) mean active speakers, using an active crossover to split the signal before the amplifiers and then direct connecting each amp to it's respective driver (speaker).

You are required to read the paragraph and from the context, determine which version of Bi-amping is being referenced.

Yes - using two amplifiers to feed the same signal to the two halves of a passive crossover speaker that has dual (or triple) input terminals.
