I got to gluing today, and the camera is actually here.. now if I can get to it before it's taken again..
The size of the circles (30"&32") relative to the table gives me an idea of how big this will turn out to be...

That's all I've got right now.. from a couple days ago.
It has one small mistake, no problem.
Yesterday, we got all the holes drilled in it and will paint today.
I need to paint it, assemble the parts, and see what happens.
As for pictures, we'll see.

Before I post pics, I must go over a few problems and try to fix them.
Measured 80w RMS from amp...remember...
So with that much power (5 sec sines), I was not impressed with the sonosub on the left side of the room (same with the old sub). I tried moving it closer and closer to the corner next. It gave everything quite a shake, but I still did not hear the deep bass. So... the next morning I tried 'crawling' for bass, with an improvement in the sense I could then hear bass to 27hz, but then created a null problem 40-45hz.
A lot of my purpose for this building was sub-40 bass, especially sub-30 and even more so sub-25. At 80w, 35hz is surprisingly quiet. 30hz is somewhat okay. 25hz is not detectable, save for the noise from the subwoofer, 20hz is the same deal, 15hz same deal, 12-13hz I finally get some pressure on my ears.
Another problem is localizing it. I have a crossover of 50hz, but I very obviously hear the bass coming from the right. I have this problem at any frequency (with any sub I have used in this room), save for 12-13hz where it IS equal and I wouldn't know except for subwoofer noise. I would use the 80hz crossover, but the localization is too bad.
It may be some time before I get the larger amp. But, I am contemplating building a second subwoofer first to even out the sound and lessen the subwoofer noise (I hope) along with add a few dB.
There is nothing wrong with the driver, is there? It's so hard to know because this is my first experience with a large high-excursion driver.
