[Horn Savant]

House is an old cheap 1880's that you find across urban Rust Belt cities.
What was at one point converted to a closet, was originally
access to narrow stairs to basement via a trapdoor. The stairs
had been located elsewhere but the trapdoor was nailed closed
at base of corner closet. This is enuf to give a speaker experimenter ideas !

Flimsy trapdoor was replaced w/ massive 1.5" thick baffle w/ two 416's @ rear
(closet 32" wide)(inspiration: Altec A4 w/ similar piston:throat). Door
opening is 7' hi, horn distance to 1st fold ~5', then continued expansion
out closet to 45 deg corner baffle + right side wall + artificial left wall +
floor. X/O is 80hz active summed L+R w/ 50w solid state amp.

Listening area is LARGE 'L' shape (walls were removed)--there are some standing
wave effects as one moves around.
Bass is much deeper and more impactful than I ever got w/ 620 enclosures.
620 enclosures are now in basement (underneath S/W spkrs *LOL*) where
they are used for different experimental set-up. One advantage of this is
the basement listening room can also use the same S/W + Amp w/ signal switching
tho here of course they are direct radiators, but still infinite baffle. Only us
Scottish could be so frugal !

You have any construction pics or a link?

Do you run a pair of horns?

Or just one horn and a pair of 416's?

How long is you horn's length?

what do you use to integrate it? Active or passively?

Power you are using?

Thanks,

Savant, nice horn and good job being a frugal scotsman. I don't have the old stair case option though. I'll have cut a hole in the floor, which I'm looking forward to. I'm going to do the IB first though, since there's a old cold air return duct there already.
