Does anyone know if one can combine isobaric loading, with dipole bass?
IE, on an H baffle, normally, one would mount a driver facing each way, but what would happen if you mounted all 4 of them on the baffle, face to face, out of phase....
Well, you would lose 3dB of efficiency, but you wouldn't gain one of the advantages of isobaric loading, which is half the cabinet volume. You might get some distortion cancellation but you would have that anyway with the one-driver-each-way system.
So with 4 drivers, I would think that two H-frames would be the way to go...
