I've been thinking about issues with summing in this 3 speaker array. You get a plus 6 dB when you sum the same signal into a single speaker.
No. I don't understand for sure what I thought I was hearing with the Revel M16 that bothered me. It could be that they just rolled off a little too fast. Could be the positioning in the room, and the nature of the room's acoustics They actually sounded good, but somehow made the room feel over damped, while the Sonys didn't. I experimented with various acoustic treatments and found that it was easy to make the room sound overdamped if I put anything absorptive on the walls near the speakers in my first room arrangement on the short wall, even with the Sonys. The delayed first reflection panel setup was a big winner however, although that was not an easy arrangement to live with, so it had to be taken down frequently. The Dayton waveguides with the JBL 2426h compression drivers and the 10" Faital Pro mids on the open baffle sounds great to me, and of course it can play a lot louder without strain. After experimenting with setting the crossover all over the place I've settled on 1100Hz now, which puts me back into orthodox territory. The off-axis looks really good there, and overall I found that is to my preference, even though the wacky 3500Hz setpoint does some nice things on some recordings. Maybe I should try it again now that I've got the side stereo channels added.
