Back Loaded Horns

[Helmuth]

Just as FYI ...

I have been experimenting with a large back loaded horn here ... Richard Long's Waldorf restoration - Page 6

That looks really loud Carl.

I prefer the word 'dynamic'! Ha, ha ...

What tickles me is that (with EQ) it is usable to 30Hz.

Then it is more a openbaffle then a horn at 30Hz.

'Yes' and 'No'. The back path is 9.5 feet in length and flares at a 30Hz rate. The cabinet is modeled after the legacy JBL scoop cabinets and aging Jensen Imperial & Waldorf dance club cabinets designed by Richard Long during the disco era. If you look at the raw response curve the cabinet is 10dB down at 40Hz. With a 10dB boost applied it is usable to 30Hz. However 30Hz is also resonance of the drivers, so in real use an aggressive 'HI-Pass' filter must be put in place to protect them. In any case the region from 50 to 120Hz has a very natural sounding, yet explosive 'whoomp and pop' which really was the reason for this experiment.

Not into small one Carl.

Helmuth,

Those look really nice! Kudos to you.
