I am also using a 1st order crossover on my horns, Yamamoto 45 SET provides 2 wpc so is fairly safe. My JBL is a E130 reconed with 2225 cone kit. I used a 1.2 mh coil in series. I paralleled 3 caps for the HF horn section(2 ufd oil/12 ufd MPT/.68 ufd MPP)into a 8 ohm L-pad.

One other point, in the short range, nothing beams like a round horn. However as I showed Bill, the secret is to be off axis with them and imaging comes through in spades.

Downfall on that is only 1 person sits in the "sweet-spot"!

Thanks for the kind words Bill!
