I'm gonna build some Sonotubes for the BTL 18's!
I'll start in a few weeks but just need some opinions. I'm gonna use aero ports, 7 cubes at 33 hz ea. Mathematically they will be 20" around and 50" long with double baffled ends and speaker displacement included. Theres that small amount for port displacement also in consideration.
Do you guys think multiple 4" aeros or less 6" aeros?
Its just something to do cuz I have never seen them with 18's and I am never done
