Ultimax 18 down-vented sub
I didn't see an on-going "help me with my sub design" thread, but feel free to merge this as necessary.
This design was inspired by the MiniMarty, but I wanted the port to be on the bottom of the box. Here's the current design:
Dayton Ultimax UM18-22
Each port is 7-5/8" x 3" x 44-3/4"
I calculated the box volume as follows:
9.969 CF minus 1CF of bracing and 0.37 CF for the driver = 8.6 CF
WinISD puts the box tuning at just over 17 Hz.
The plan is to have a pair of them (hopefully front left and front right, but right and left rear are also options) driven by a Behringer NX6000D.
My question is - what am I missing before I start cutting MDF?
