Hi Steve,
Welcome back. Thanks so much for joining us.
I think you are brave. I run my 288’s no lower than 800 and often closer to the 1.2k I mentioned. I guess I’m a bit of a chicken.
Is your system still as we see it?

 

[Steve Mac]

Yes Cal,
It sounds best to my ears at 550 and I’ve run the system at hi volumes for hours...no guarantee though. 🙂

True point source once digital time delay is used to 'move' the 511's driver back somewhere around/behind the 515's acoustic center at the XO point. Without this it's not that good of a sound system.

From experience I find it hard to believe it sounds fine without some aerodynamic smoothing of the 511, but he claims no.

Yes, on the time delay...currently using a dBx DriveRack venue360
