I’m getting ready to build a test cabinet.
Unfortunately my volume maxes out at 5cF, and not my desired 7cF. Bracing and wall thickness will be blamed.
The slot port for the 7cF was 2″ x 15″ x 18″ deep. This is according to this forum (I didn’t do the calculations my self).
What changes need to be made to the port for a 5cF enclosure?
I use the green Roxul 3″ insulation. This along the interior and back walls. This means the driver behaves as if it is in a larger enclosure. This may make a difference.
I read about group delay, but am unsure what it is.
