Thank you, Mannermusic.

Found a copy on Amazon for a good price. It's on it's way.

Through sleet and snow and all that.

Thanks for taking the time to respond, Grumpy, Earl.

I think that there is a little more here than meets the eye. I've seen the schematics but don't know enough to compare them. Also, the old...

I wish to build a pair of JBL speakers, in an 8cu. ft. bass reflex enclosure, (JBL design) using a 130a 8Ohm bass and 175DLH 16Ohm horn, driver, lens. I do not, however, have the proper N1200...

Is it just an impedance difference, 16 vs 8 Ohms or is it more than that?

You've always been so helpful in the past, I know somebody will know.

Thanks, Steve.

I have been considering building a single cabinet using the plan for a 130a bass, 175DLH and N1200 crossover in a 16 ohm system in my garage. I have an old Fisher 90X tuner, a Heath mono preamp and...

Thanks gang, for your input. The original idea was building the ultimate JBL horn speaker. I had accumulated the components for a 4345, subbing a pair of 2123's for the 2122's. I saw the EV Patrician...

Greetings folks. I have long been a fan of folded corner horn ( Hartsfield, Klipschorn ) designs. Tooling around the Internet, I found information on the Electro-voice Patrician IV. It is described...

Thanks, 4313B, for supplying those plots. Stevedel

Thanks ivica, for the reference to the section, on the site, that includes the bare driver response curves. It will be most helpful. Regards, Stevedel.

Having collected most drivers and horns for a pair of 4345 clones, (2245H, 2420 and HL91 horn-lens.) I found a pair of LE10H-1 10 in. in need of surrounds. I also purchased a pair of 2404H tweeters....

Thank you, one and all.

I found it! It seems that one of the screws holding the2245h to a plywood backing for shipping had come loose and found it's way into the basket somewhere. I had turned...

Greetings again,
As the woofer is tilted, with the cone facing down, the rattle is more of a sliding noise.
Is there anything, besides foam, behind the cone dust cap that could be jarred loose?...

Greetings one and all,
I have been following this forum, with great interest, for some time. This is my first posted question. Not that I don't have them, but in searching this forum, you guys have...
