Boxes and 421's in NC

[gearfreak]

Have never run either past 1200, both do that just fine.
Hazarding a guess, the 515 cone DOES seem lighter, so maybe will go higher.

My 515-8G's are topping out @ ~6k by ear, in recent manual frequency tests, entirely overlapping the 288, using my 800hz franken-XO based around the EV XEQ-808.

* I should repeat the tests with the MF/HF disconnected to be sure, and observe off-axis in more detail.
This was one reason I'd like to try 416's.

That said, the MF is one thing I'm not particularly monkeying with atm.
