Active crossovers

Hello, Rives, I think I understand now. I have sent Albert an email asking about how to best bi-amp. From a previous email, he strongly suggested biamping but did not get into technical details.

Drrasta, yes, I have though of the Mod 5 conversion. I still would like to bi-amp them, in either form. I've checked with Albert and the crossover point between the bass and mids would not change, so the biamping would work fine before and after conversion.
Have you heard them before/after the conversion?

thanks,
KP

KP, it looks as if you were thinking about passive bi-amping. While there can be gains made by doing so, they do not in any way, shape or form compare with the benefits of active bi-amping. That is, if everything is set up right and the speakers do not have a ton of "passive parts" in them to begin with. Sean

I though having an active crossover would handle all the problem, since it would sned the "highs" and "lows" to the resprective amps, and them have one amp on the high/mid module and another on the bass.

What I'm reading is, then, that even after splitting highs and lows into the correct speaker input post, I still have to worry about the inside of the speaker?

Wish I had a dry erase board we could share, it'd be so much simpler! I'll try anyway, this is what I thought!

pre---xo---hi amp---self-contained speaker box (high/mid)
|---lo amp--- " " " (low)

So in this case the mids/lows are phisically seperate at the speaker level. This won't work?

Since the speakers already have their own integral crossover, you would be crossing over electrically BEFORE the amp and then again after the amp inside each speaker section. In effect, the passive crossover parts that divide the lows from the mids would just be "exra junk" in the way of the signal and redundant unless you took them out of the circuit path.

I and others are talking "theoretical best performance" here, so keep that in mind. I guess that we figured if you're going to go to that much trouble to buy the amps and crossover, you might as well get the best results possible. You could actively cross and leave the speakers alone internally. It would be a step up in amplifier efficiency and power handling for the speakers, but i don't think it would compare to the total benefits of "direct drive".

Keep in mind that even if you did actively bi-amp, you would still be relying on the passive crossover components between the mid and tweeter if you simply divided the speaker between highs and lows. As such, you REALLY do need to discuss this with Albert and see what he thinks is best. After all, he should know his product better than anyone else. At least one would hope so.. : ) Sean

Sean, I see what you are saying.

I've seen your other post. You, my friend, aree the Poster Chilp for multi-amping. I was hoping you'd jump on this thread!
So in my case, I'd need to at least tri-amp for max results (that beign the total removal of all passive crossovers). question mark.

I'm waiting for Albert's reply.
