Hey michael, that's a great looking speaker!

I think I'm leaning toward the Nat P Wave and possibly done in verticle polylam layout. In that case, the finish would be polyurethane over BB verticle layers on the wavy sides and a nice complementary veneer on the baffle. I just wonder if all of those verticle wavy lines would accentuate the curves or be too distracting? If I'm not going to see the polylam layers, I may opt for one of the other methods.

Rough dimensions would be as follows: H40" x W10" x D12", curve wavelength 20" and amplitude 1/2" --> If the sidewall were a soundwave, that corresponds to a audio frequency of 675Hz! Also an internal volume of 56L before driver, bracing and port subtraction.

Also, a higher tune or even a sealed enclosure for the mains may be easier to mate with that SDX15 sub in the planning stages. Any suggestions as to how best to tune and cross mains to the sub?

Thanks for all of the advice!
