I am about to undertake my first subwoofer build and would like some feedback on my box design before I begin.
I will be using a single Stereo Integrity HT18 in a large ported box with the goal of 115+ dB from about 80Hz down to below 20Hz.
External Size: 24" x 24" x 75"
Net Internal Volume: 18 cubic feet
Port: 18in x 6in x 45in
Port Velocity: 9.3 m/s @ 20Hz (lower as freq. increases)
The speaker will mount in a down-firing configuration in a 24" x 24" x 2.25" baffle and the port will exit the opposite end (top).
Does this look like a good plan or am I missing something?
Thanks in advance for looking.
