twin drivers cabinet Fostex FE126E

Now the dual driver box is too deep (21") and is swapped out for a mtm with lineaum tweet (not time aligned, ewwwwwwww, but f3 is closer to 80hz). Maybe I'll hook up the bamboos later tonight.

I should have ran an extra set of binding posts, but worst case scnario, I figured I'd run them like a von schweikert.

The dual driver von schweikert has cleaner midrange than their design with a single mid (imagine that with 2 drivers).

Bipole could have been an option also.

An open backed box is hopefully in the works as soon as I can talk to my carpenter. It's 2' tall, 2' wide, and 10" deep. Driver is on the bottom edge and 9.2" from the right edge. It will be sitting on a dual 15 bass module. Lots of differing distances from the driver to back side will make for lack of suckouts present on an open baffle where a driver is mounted exactly in the center.

With the Feq of the open baffle and the large front baffle, it will make it to 200hz easy.

Best mids I ever had was a tang band w3-871s on an open baffle.

But the dual bamboo design, it was my first build on my path.
With the loudness button on, it fills in the mids nicely.
Without it, there is a midrange suckout and zero bass.
That's what you get with a box front baffle 8" wide and 13" tall and 21" deep. I could fix all this with +3db at 500hz and +6db from 250hz down on a 10 band equalizer.

Run wide open, it wanders away below 700hz (baffle step corner). Then sealed box rollof below 200hz (qtc .45 to simulate open baffle lack of back pressure, f3=178hz).

In the very narrow vertical sweet spot, it is wonderfull (with loudness on and the 12" for bass). Without all this help, it sounds horrible.

Remember 12' away, placing a cd under the middle of the bottom made a big difference with a dual 4" (5" frame) drivers setup.

Just like the omega minuet that was an inspiration.
