Till E.
I have done same project. Did you use 1.4 mh coild for 2226J?? I had some 2 mh coils on hand that I used. Did you remove the foam from the ports also??? I used 15 ohm parallel and 30 ohm series attenuation on the horn with .47 ufd compensation. The .33 ufd probably works better on the JBL 2425 or 2426 driver, but I think the 2418 is cheapened version and has less top end. With a mild 30hz eq thrown in they sound great. Let me know how you have implemented yours. I am running off of Marantz 2238B right now, but best sound came from 2215B. I too have had the 2A3 Paramours hooked up with mine. While they sounded good, the Altec A7-500's blew them away. I must say though, the Altecs work best with the flea powered units and don't like the wattage that JBL 2226's like to run in their best environment.
Thanks, Ron

I'm biased sure, but...

The Professional sevens are really sweet. I put together my first Professional seven π Speakers in 1980. They used JBL 2205 woofers and JBL 2105 mids. Man, pro seven π's are seriously good sounding speakers.

we're so close to each other, gotta get together. I know, I'll drive down to Columbus, pick you up and we'll do the Route 66 thing to Tulsa and Wayne's Warehouse.
All I can tell you about the crossover is that it's the Eminence 1.6 Wayne specs for the Pro with the 10uf cap removed and no Zobel on the woof. I haven't removed the foam. They just sit in the corners of the TV room and go BANG!...BOOM....and pockita-pockita-pockita (sound of Bell HU-1 dust-off).Driven by an Outlaw 1050 A/V receiver which sounds dreadful when I move it to the music system.

I'll have to dig out the 7 plans then. Once the 2's are done, by next week, I think, I have to re-build the Paramour right channel. Then a tweak or two on the Foreplay.
And then....there's a 50 per cent chance I'll be ending my exile and returning to Florida in November. Yay!
I may be forced to build the 7's out of solid Honduran Mahogany.
