I'd also probably use a fly-cutter instead of the Forstner bits, but that's a bit hairy for folks who haven't used them before.Comment

Re: 2" Driver Line Arrays - How to Angle Parallel Drivers?
I may be about to be schooled, but this seems wrong to me. Geometrically, as long as the acoustic center is actually centered on the XY planes and the depth of the cone remains a constant, the distance that sound has to travel forward to meet its "sister" signal should also be constant despite changes in the relative z-angle as it will be a function of cone radius and depth. You should be able to test this practically by putting the two drivers on a hinge and holding a piece of string on the dust cap of each driver. There should be minimal difference in tautness as long as the drivers only change angle on not distance. In addition, in the concave version (where the drivers are crossing over), the more energetic area of the sound waves will be interacting, and thus I would think more potential for larger gating effects. On the other hand, at a "tangent" the less energetic parts of the sound waves would be interacting due to poorer dispersion characteristics for larger cones, no?
Ok, educate away.Comment
