Thanks lol. I just want to get everything right. My project exploded into something a lot more ambitious and expensive, and Im getting everything at once. One small incorrect calculation and my screen wont fit, or I might need a different throw lens in my projector, and all sorts of problems that arise. This is one of the simpler issues thankfully, but still it has to be done correct.I have to say that your posts are rarely dull 🙂 You'd set this up like a trig problem calculating the front-side of right triangles for fairly exact answers but very off the cuff it sounds like you're exposing about 1/3 of the depth to the x-axis, but only a 33% max of that since it's a 30 degree rotation, and you'd offset that by a portion of the width absorbing in the z-axis (again, 1/3 but only 33% max).
Assuming a rectangular shape you can call it about 9.5 inches at the widest horizontal of the biggest imaginary rectangle formed by the speaker's footprint.
Do I understand correctly that even with 30 degree toe in, a 7 7/8 inch wide speaker with the specified depth only becomes 9.5 inches wide?
That's not so bad. It looks like I actually only need to toe in about 19 degrees, since I was visualizing things wrong. I will measure myself soon when things are set up. Finally ordered my AV rack.
