Active Crossovers

I have a big air core their now. I think 14awg and fairy close spec to stock. I got it a while back. I forget where and what it is.

What is woofer cook?

Never ever in 14awg, the bigest aircore in 10awg have double resistance

L106.8

6.8mH 10awg Litz, 0.49ohms DCR, 45mm H x 178mm D

P.S
The largest I've ever seen is a 6 square millimeter wire aircore in Audioplan speakers.

What is woofer cook?

In a two driver loudspeaker -- say a woofer and a midrange/tweeter -- woofer-cooking uses bi-amping -- one amplifier on the woofer and one amplifier on the midrange/tweeter -- to manipulate the SPL of the woofer versus the SPL of the midrange/tweeter.

Woofer-cooking allows you to dial-in the relative output of each driver, thus creating a custom tonal balance. This is in contrast to level matching the amplifiers in a bi-amp configuration.

The distinction is not clear. FWIW this is a phrase I've not heard before as well.

Are you saying that in the first case the passive crossover of the speaker is being used and in the second case it is not?

I love contributing to the language of audio: sonic cues, woofer-cooking.

No, it has nothing specifically to do with crossovers, active or passive. Of course there has to be some way to divide the full range signal between two drivers.

It just has to do with having a configuration which lets you amplify one driver to a higher output than the other driver. Woofer-cooking can also be accomplished by attenuating the amplifier drive to the tweeter. Although this might be more appropriately described as "tweeter-trimming."

Ok... I'm going with this really isn't a thing. The reason being you need a means to vary the output of one with respect to the other. That implies a level control somewhere. It might be in the crossover (my speakers have level controls on the back for this purpose) or might be in the electronic crossover.

Why do you call it 'woofer cooking'??

Because one uses much more power to drive the woofer than to drive the other loudspeaker driver. Using 2X or 3X the amplifier power on the woofer is cooking the woofer.

If I have two identical power amplifiers, I would try vertical biamping. Lay longer RCA cables and short speaker cables for the power amplifiers as close to the loudspeaker as possible. Advantage: higher channel separation. Disadvantage: second pair rca cables
Flexibility: Any level controls on the amplifiers enable fine-tuning between bass and mid/treble. I would try both horizontally and vertically.
