As some may have seen already on some fb forums, I have designed and build a new 18" BR cabinet using the Faital Pro 18XL2000 driver.
Tuning is 32Hz with a port of 540cm2. Net volume is around 140L.

I have some pics of the build and response, but have to find a new website to host the images.

That is very inefficient.

Won't get more efficient for a BR. Maybe lower mms driver or lower re driver to get numbers up, but a 18XL2000 in this volume is quite it. No magic.

Slightly bigger cabinet will gain 2db at 40Hz. But if compact was the idea, then all good.

There is a nice spike in efficiency at 50Hz.

Yup, we are all just Hofmann's bitches in the end, like it or not.
