crossed to mid horn at 500 Hz. (picture above in the home of the previous owner).

Think it uses a 12 in. JBL musical amp driver (99 dB) re-coded without the metal dust cap?
IIRC the length of the folded horn is exactly 1/2 the path length of an complete sign wave at 500 Hz so it's wired 180 Deg out of phase with the mid horn and both horns us first order X-over.
Which, of course, is a problem as the mid-bass horn driver is only 6 dB down at 1000 Hz and 12 dB down at 2000 Hz and etc.
Same applies to the mid horn. Driver is seeing 6 dB down at 250 Hz., etc.
I am now of the opinion that horns should the bi-amped and use digital z-over (steep) with phase/delay correction.
Especially as I mostly listen to digital steaming anyway. :-(
First they came for the dumb-asses
And I did not speak out
Because I was not a dumb-ass
