Linkwitz Transform and enclosure

I understand the purpose, implementation and benefits of a Linkwitz transform just fine. However, my question is on the optimum enclosure to use it in. Of course, an enclosure w/ a Q of 0.707 would require the least amount of gain from the Linkwitz to achieve the desired results but the power handling would be less. A higher Q increases power handling but at the same time demands more gain from the amplifier.

To those who have used a Linkwitz transform, what in your opinion is the best starting Q for an enclosure considering both power handling and also efficiency? I am looking to have the box finally tuned to Q=0.707 Fs=15hz. The setup will use 4x Audiobahn AW1200N and 2800 RMS watts available, if that information assists in your answer.

Thanks,
Matt

Design a sealed enclosure with a Qtc = 1.00, then drive Qtc back to .707 wth the compensation circuit.  I don't think you'll be able to get your fc down to 15Hz without a lot of compensation (and a LOT of power compression) with those drivers as their fs is way too high.  You need a woofer with fs down around 20Hz or lower, not up at 31.5Hz like those things have.

A Q=.707 is called "max flat". It will offer the depest possible extension with the least ripple possible. A Q=1.1 is "max power", and on the other side a Q=.5 is "critically damped". Knowing this, now, which would you choose?

I have been using this method for years, although we call it the BFI method. That's "Brute Force and Ignorance" and it is the method I prefer. TINY enclosure, with TONS of power, and equalization to fix whatever is wrong. I run a single Eclipse 12 with the DA7232 amp in my civic presently. Eventually, I will have a dedicated AltoMobile UCSPro for it alone. (got two of 'em... just need to install them now) 31 bands of TRUE parametric EQ oughta do the job...

15Hz is still going to require a large enclosure, even in the car. It will be VERY difficult to get a flat response in the car, also. I know, I've been trying for years... Transmission lines, passive radiators, sealed, vented, bandpass... I've tried 'em all... It will take more than a single band of fix to reach a flat response.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
