Sounds like either the title or the last line of some old Amurrican folk song that the Carter Family or suchlike woulda mourfully wailed."The concrete horn is my grave"
sounds like aperiodic damping to me...Won't it mess up the acoustics if you start stuffing it full of dead bodies?
Recommendations?
I was kind of eyeing the Klipsch La Scala, or maybe even the Klipschorns.
I dived into horns with something similar but with 12" woofer and cheaper chinese drivers, bough ex-demo from the distributor at 40% off.
Started with this 2-way:
Then converted it into this 3-way adding a Visaton horn tweeter and replacing the original horn with a tractrix.
(the overly-tall horn stand is a temporary prototype, made of Ikea leftover plywood drawers)
Then got fed up with the permanent work-in-progress tweaking and as it needed a new woofer and was getting too expensive I sold them.
Opera Consonance M12, not a bad concept, but the execution seems to be sub-par.
First of all, I'd measure the Chinese drivers individually to verify whether these are actually up to the task > I expect not.
The horn appears to be a clone of the Arai A480, albeit with a "dirty" throat and without vanes.
Even an original Arai A480 should not be used from 500Hz, but rather from 900/1000Hz.
A proper round-to-square horn adapter may improve performance, especially if the Chinese driver is ditched in favor of a FaitalPro HF10AK,
aka the poor man's TAD TD2001.
I'd probably also replace the woofer with a FaitalPro specimen.
Naturally, the crossover must be revised after these modifications, or: dump the crossover and go active.
This is what the interior of an A480 is supposed to look like:

That's a speaker I built probably 16 or 17 years ago.

Is that a 511B or an 811B? I cannot tell how large it is. What driver is on it?That's a speaker I built probably 16 or 17 years ago.
Not a bad idea -- well... except for the Klipsch part.Klipsch meets Altec meets Jbl?
Those are Lascala clones I built for a friend of mine who fell in love with with the hybrid Khorns I built using Altec 511B horns, 902 drivers and Beyma CP-25 tweeters. The Khorn clones use ALK universal crossovers. The Lascala clones use ALK custom designed crossovers to go with the Lascala bass bins. The Lascala clones use the same mids and tweeters as the Khorn clones.Is that a 511B or an 811B? I cannot tell how large it is. What driver is on it?

Gorgeous.
