Tom D. Indeed we avoid aligning the geometric plane of the XO panel normal to the velocity propagation wave. The vertical boards are aligned to present minimal area to the velocity wave. Adjustable resonance control is an attractive mechanism, both for the XO and the drivers. My approach tries to control the forces without the complication of user adjustability. I have prototyped tunable control and the future could lead there. The combination of bronze and Panzerholz works very well to dissipate energy while providing considerable strength. Progress is being made.

Seems to me that an outboard crossover might make the most sense.

I agree. Outboard has lots of advantages. But I also want a significant upgrade that doesn't require the outboard box. I'm able to get a considerable inboard advance over stock. Outboard is better.

Agreed upon. When going outboard with a Dunlavy modified crossover there was a gain in performance even more so when placed on a resonance grounding platform. Not a so called isolation platform as those trap and slow burn the exit of resonance. You want a nice quiet exit thru reactive materials with the proper conductive geometry as a tour guide to the exit. TomD

The floor interface is a complex problem, especially considering that each floor is unique and sometimes substantially different from other floors.
