Here's my latest. Klipschorn bass bin; JBL 2350, 2470; Bob Crites tweeters. Stock Klipsch AK-3 crossover (400Hz and 6k)
That JBL horn is exactly the perfect size. I'm surprised: I thought with a 1" driver and the throat adapter, it might be too deep. But no, fits like a dream.
Sound: a tiny bit toppy (the 2470 could use a little bit of attenuation) but amazingly good. I'll run some measurements later, see how the 400Hz crossover really suits the 2470/2350 combination.
