So, I am getting closer to the point that I can make some sawdust - plus a local friend just bought a 4x8 and a 4x4 CNC that he is wanting to put to work. The 4x4 has a 4-axis head on it, so there is some possibility for making the facets I want. Anyways.
I think the big Viawave loaded in a waveguide will offer enough sensitivity to do a 2.5 TMM with the 8" CF Rival woofers, and play low enough to blend well. I am still doing some ciphering on that combo, but I believe it will yield a very high-end tower capable of playing below 30Hz etc. Alternatively, I have those hugeass Beston things that would work from a sensitivity and playing low enough perspective. Benefit to those is they are already loaded into a waveguide.
Another alternative is to go sealed with the 8" (approximately 50-55Hz with a Q of 0.7), and fill out the bottom octave or so with the "Scan Speak" 10" subs I bought.
Anyways, this is a place holder for an eventual build thread. Even if I could finish by Iowa - I won't be hauling them anywhere.
I have a signature.
