Default What the ???

I decided to try an experiment aka emerald physics. I cut two 6in holes in a board and mounted two alpha 15a,s on the back. There is less than no bass. Doesnt seem to work at all. My board is only 16"wide. Is that too narrow? I really dont understand how this is supposed to work.

Yes it is too narrow and you need to add a 6dB/oct boost LF to overcome the cancellation of the open baffle arrangement.

Are the drivers actually sealed to the baffle?

I once cloned the Emerald Physics CS2 and had plenty of bass even before adding eq.

The alpha driver never became my cup of tea. Same bass signature regardless the source material. Not very dynamic either.
