   Of course, if you build already existing designs, they will perform like intended. 
In my case most existing deisgns won't fit my needs.....

	a diffraction slot filter in front of a hot 15" would tend to even out hot spot and horizontal dispersion to ~60 degrees off axis - but might introduce a cavity resonance one might muck with 7"x10" or 8"x11.5" ellipse - oval could look "naughty" so reason nuff to use (?)

	This will indeed get us bandpass characteristics. Of course higher freqs will 'escape' because the 'hole' is directly in front of the speaker... but I guess the low mids (100-250Hz) won't be good.... It's not only beaming I was talking about. It's more the fact that the mids, even if the freq plot is smooth, won't be that detailed. I have some really smooth sounding 15/2 type cabs, but it isn't comparable to 10" and smaller mids.....
