OK if I paint them black using automotive heat paint.
No problem with paint, just keep the paint layer thin. I've painted a number of raw aluminum sinks and used them for amps like ACA, M2, Aleph-J and MoFo.
Hoping to get some help for a friend that now has 5 amp camps and attempting to run his Klipsch Jubilee HF (horns only) on balanced XLR. At first, he was running two amp camps in stereo but tried balanced expecting higher output on his 8 ohm horns but he is getting 5db less vs running RCA bridged. Does anyone know why this is? I checked wiring multiple times and it’s correct. Below is his setup.
Marantz 7703 XLR outs using MOGAMI XLR cables
..into XILICA XP- 4080. DSP signal processors. XLR outs to ACA amps

What does the impedance look like?

Attached is a picture of the horn.

Some info here... could not find any official info on impedance vs. frequency.

How does he know it is 5db less? Putting a test signal into the amp and monitoring the output across the driver with a VOM or a scope?
...is the output of the dsp XLR the same as the RCA?
The xlr output is the same if the amp was used in stereo mode.
Ok, now I'm really confused.
The DSP you mentioned only has XLR out. How was it connected with RCAs?
Are you taking the output across the two speaker blacks?
He converted the xlrs with an adapter to rca.
At first, he had 2 amp camps running 4 speakers in stereo by using xlr to rca adapters. His center channel was being run off an amp camp 1b mono amp.
He acquired 3 more amp camp 1.6 (stereo) amps and is now trying to run all of them XLR. He has been hooking them up according to the diy build guide.
One thing I did not mention is that all 5 amps he now has have been upgraded to premium parts and the changes were made based on Tungstenaudio's recommendations.
Schematic is attached (does not show the bridging resistor change to 68.1K ohms)
