Re: Need more head room, long, narrow roomLisa has never given us the ceiling height of this venue, but I'd guess (given the other dimensions) that there's a good chance of at least a 10 foot ceiling, possibly more. But let's work with your "horns at 8 feet" spec.The 615's have a nominal 50 degree vertical pattern. Your given figure is for directly on-axis sound. The actual pattern is more forgiving than that. The difference will tend towards the LF/HF balance at the rear. So I wouldn't worry a whole lot about the degrees of the tilt. The salient factors are height, angle, pattern control and SPL. Pattern control and SPL are set, so work with the height and the angle. And if you really must have more beyond this, delays are in order.
