I recently posted some speaker concepts I'm considering.
The plan is now to develop all of them!
A: HE3 in slightly modified form with a single 10" active woofer
B: AV8 is already in my range
C: HE2 is already in my range
D + E: coming soon
F: coming soon
Out of the surround speaker options:
The two dipole surrounds are shelved, the third is AV8 already in my range and the one on the right side is currently in progress - it's a Coax 8" driver.
