Ever think of building a Cornu Spiral horn? Now you can!

Cal and X and everyone aboard this longstanding thread. 3000+ posts!

As I had a couple of Faital Pro 3FE22s, I couldn't resist putting together a pair of these spirals. They're 24" across with 1/4" ply fronts and 1/4" mdf backs, 3" foamboard dividers, hot glue first side then SilkaBond Instant Nails FAST on the second. Puffs of polyfill in the centre and the first 8" or so of the two longhorns. Gee, mucho impressive - but y'all knew that! Good volume from the Faitals with my fleawatt RH84, big noise with the Tubelab SPP!

Thanks for the inspiration and ideas on this great project!
