A few years ago I pressed a pair of old Pass A40 stereo amps into service again. I bridged them so I had a pair of mono amps and fitted them into the base of an open baffle speaker project based on the Pure Audio Projects Trio15 Beyma TPL-150H.
I've attached a file with a few snaps of an early stage of the project.
I've grown very fond of these speakers, but I fear my aged A40s will rapidly approach the end of their useful life.
As such I've started to think about replacing the A40s and I thought I'd take the occasion to rework the speakers too.
I came across the Spatial Audio X3s . See 1st attachment.
It strikes me that Spatial has designed a form factor for open baffle speaker, that one might readily adapt to a DIY speaker project.
You can see from the attached snaps that the speaker appears to have 2 baffles. The front one (wood colored) mounts the drivers and a second described on Spatial's website as:
I'd like to replicate something like these speakers (at least visually) using the drivers I currently have, so...
Does anyone have any thoughts on how to "isolate" the "secondary sub-baffle" and what material to make it from?
In what I've begun to imagine, I think I would use three amps per speaker and digital crossovers. I think this would provide a great deal of design flexibility.
Finding room to mount all of this will likely take some ingenuity. I do like the idea of having all the components mounted in the monolithic double baffles and the baffles supported by a simple stand. My wife, an architect with minimalist sensibilities would prefer such a design.
Any recommendations on how to go about this appreciated.

"A secondary sub-baffle provides resonance draining properties and houses the isolated mid/high passive crossover and integrated N-Core power amplifier which drives the subwoofer.
