A box that we are currently developing. Here's a picture of version 1, and a 10 meter, 28.3v ground plane measurement (biamped, 2.83v into both, 8 ohm nominal bands, passive crossover on the 4594he, 750 hz crossover, 18db/octave Butterworth lopass, 24 db/octave Butterworth hipass)

There is still some work left to do with rear chamber volume, VTC, and the transition from throat filler to horn entry to try and fill in the dip 400-600, but so far very happy with the sound of the box with no eq at all, thr 4594he is very well behaved on this horn down to 750.

Passive crossover development will begin as soon as we complete our final tweaks.

Only in its chlive of drivers.

The horn in that thread features a 90 degree bend and offset driver configuration. This is normally mounted driver with no hard bend in horn path, and no ports. Optimized for high sensitivity above 200hz for use with a midbass cab
