Nice looking design! A few comments though (based on designing and measuring many arrays with domes, planars, and ribbons). The planar tweeter doesn't eliminate comb filtering. A simple set of...

The longer ribbons / planars / AMT's do beam in the upper octaves but the good ones in the 60-80mm length range sound excellent to me.

There are ribbons, planars, and AMT drivers - all are different in the way that they operate. The magnetics play a big role in the sensitvity and there are units available that will compete with...

Thanks for the woofer graph. There's an edge resonance at 1.4K (5db dip) then the first breakup peak at 2.2K - not an easy combination to work with. I would love to take a crack at it for the...

I would suspect that if the stock crossover is at 1.8K then the designer chose that in order to minimize the upper end breakup modes in the woofer. These types of drivers often have issues with not...

It's a proprietary driver that I just imported. Personally I feel that the longer element drivers like the TPL-150H beam too much in the vertical plane and are better suited to arrays than a MTM...

I have designed theaters where we used arrays for all speakers as well as projects where arrays and non-arrays were mixed. Many systems simply won't allow arrays in each position due to room or...

Wow - you guys have listened to a wide spectrum of speakers! The format determines quite a bit of the sound (and of course how it's executed). My feeling is that electrostatics and full-range planars...

Shading is used to widen the vertical coverage and I think for the great majority of rooms this wouldn't be a problem. These can be scaled depending on how much output is needed. I have 4" drivers...
