Cool, makes sense.One last thing, the sealed box resonantes at Fo, so thats where control is the least. On a vented box, is control the least at Fb because thats where it resonants? Or is it Fo and Fb because theres a Helmholtz resonator and the shifted mechnical resonance of the cone? I wouldn't think its Fo because apparantly thats right no near Fh.
Thanks!
