Did someone ask for measurements?
Before I show y'all these, just remember - they were done with a cheap eBay SPL meter, no cal file, with the C weighting option checked. The most accurate part of this setup is the Behringer UCA222 used to capture these.
First, Wolfhorn SDX by itself, listening position. 90dB sweep. This is the loudest I can run it without wall panels vibrating, and the loudest I will
run it without a highpass. SDX drivers don't grow on trees, and I can't afford to replace them.
Now, before I show the other two graphs of both horns through the Reckhorn, I want to remind you how the B-2's highpass and EQ is currently set (purple line):
Ok, now both horns through the B-2, 90dB sweep:
Now, take this one with a BIG grain of salt. This one had the walls rattling, which almost certainly got picked up by the meter. 95dB sweep (or so it should have been):
All of this is with the meter at LP.
