One other thing, what if I have no back chamber at all? I modeled it in Hornresp without a backchamber and came up with very similar results. In practice though does it sound better with a backchamber?BTW: Is Alpha 6 even a good candidate for horn loading? It does have 20oz magnet, rather small for its size (for horn use), I *think* you need large magnets/strong motor for horns if using a backchamber, but I am not certain.
Thanks!
