The KOSS Electrostatic unit was still installed , so I removed and checked resonance .The resonance was 136 HZ. I then tested it in horn assembly and the result was the same : 136...

[quote user="Romy the Cat"]. What was your resonant frequency after loading? The 416 are 25Hz drivers, after loading and with two drivers it might be deep in teens. From the picture it looks like you keep the back chamber of extra large space, or eve...

Window needs to be sealed with non resonant baffle. 416's sound spectacular in inf baffle ! May be possible to horn load to a corner using standardgood design precedents with good throat coupling like my previous pictureThis picture: Back of 416's in...

Before experimenting with the Hi power Electrostatic module, I used 416's in my large corner horn. They sounded extraordinary (ran with inf baffle to basementand made me realize how much Altec/JBL enclosures suck with their poor deep bassperformance...

I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

Up to the first fold the horn is somewhat conical as seen in post #1 picture.This picture shows the exit w/ additional angle wall (making for "corner" loading).This has a greater (uncalculated) flare something like a compound CD horn.Resonant F unkno...

HelloI've always wanted to try an ESL as a horn driver:So I employed a hi power Koss 3-layer bass module cut from Koss "model 2" spkr.Polarizing voltage was low on Koss design so it was upped to 3kv w/ custom PS.Horn is old closet that had a trapdoor...
