Alright thanks dave, I think I'll take my chances with getting my dad to use a router to attempt to countersink the driver

Also, I don't fully understand the angled interior bevel. How can you screw the driver into the enclosure after effectively thinning what it's being screwed into

The MA baskets are very open at the back so you can get reflections from a vertical wall on the cutout. You can bevel just that part not near the screws. If you built with ply like we do, what is leftover provides enuff meat for the screws.

If you want to go nuts something the heads in the direction of all-out (see picture) works too.

Click the image to open in full size.

Default this is probably the only time i can get away with saying this....

I have a dremel for routing/shaping the rear of a cutout, but i have in the past used a coarse rash and dare i say it? even a Bastard file every now and then...less woodworking and more wood abuse

P10 states about the MA drivers having very open backs, which is true, but in contrast to some Neo drivers which are very open, In my experience, the MA drivers are open but transversely rather than axially, with respect to the cone, so naturally and unfortunately reflections will occur. unless rounded off the inner edges have a profound affect in these cases.

If you get the back of the cutout at an angle (we do 45 degrees) then waves traveling sideways get reflected towards the back of the box and not right back thru the cone.

To me the TQWP is the nicest sounding loudspeaker that I've heard and love mine.
