I started my sonosub project last week. With the Christmas present of a 15" titaninc, I'm on my way. I'll show my progess up to now, then I'll beg for hints and suggestions.
Here's a pile of oak lumber for the visible disks ready to be cut up. Inside disks will be made of MDF.
Made small pieces out of big pieces
Lining up the oak pieces for biscuits, dont want any showing around the edges.
Boards biscuited, glued, and clamped up.
Driver circle cut out
Test fit of the driver
Legs drilled and fitted with stain applied
Bottom plate drilled and stained for accepting driver plate legs
Now I'm at a point where I need to decide what I'm going to tune the sub at. Using the sonosub calculator, cutting the tube to 4', this is what I get.
I've read that tuning below 20hz will not gain me much of anything, between all the FS, xmax, vas, qts, and FU's, all of which I have no idea what the heck they mean, except for the last one, it's giving me a headache. So I guess I'm just asking you guys if I'm on the right track.
Once again, all hints, suggestions, and critiques apprecitated.
