Down-Firing Straight Edgar Style Mid/Bass Horns




EduardG posted this picture of his close field mid/bass horn on another thread, and I thought it deserved it's own thread. When I saw it I flipped my lid. Ed says he has rubbed elbows with Bruce Edgar for twenty five years. It shows! I prefer the name Get-Set-Go horn, because it's so simple it's elegant.

I think this horn is important, because it's a front loaded horn that is very compact, and is 110db effficient. I get that number from Inlow Sound. He lists his M/B horns as 110. That means you can hit those 110db peaks with no distortion at one watt. One watt amps don't just sound good, they are also much much cheaper.

Downsides? Well you are shooting the sound at the floor instead of the listener. I imagine you would take a sound quality loss on that. With horns when you start making compromises for the sake of size, then you pay in SQ, bandwith, or both. Of course most mid/bass horns have the driver facing in the wrong direction don't they? Only the typical Edgar mid/bass, or half loaded horns like Altec are aimed at the listener. Bandwith on this horn is pobably two or two and a half octaves. I wouldn't cross this horn over any higher that 300-350hz, just like any other folded horn. 400hz may be the raggedy edge.

John Inlow makes an 80hz horn that's 3' 9" long. Stand it on it's mouth, and it's 2' 3" long. A 27" by 27" footprint puts it in the ballpark of Klipsch Heritage speakers and others.

What I have no knowledge of is, what happens to soundwaves in the 200hz to 400hz region when you bounce it off a waveguide/floor? Same as any other folded horn I guess.

I hope the horn masters usually skulking around here post a comment about this horn. Too many names to type. Hope Ed G will tell us more about them, and their background.

Asylees are always free to howl at the moon.

Big speakers and little amps blew my mind!
