Building L46 Clone,what is the crossover point forJBL L56 and L46

[chuckrock]

hello,anyone know how to get technical info on L46 crossovers?,specifically crossover points .Building a l46 clone with a beautiful old pair of RGD cab's,using 034 jbl tweeters and 8" jbl woofers 2118H-J.also any other important info about crossovers as it pertains to this project,obvious newby am I.

They use different crossover points. The L46 sounds much better. I might still have a pair of L46 XOs in a box around here somewhere.
Anyway, spec sheets:

3000 is really as low as you want to go with the 034. 3500 is better. The L56 is at 2200.

thanks a ton rdgrimes,building for myself but might sell,so l46 xovers desirable,ive been searching for l56 xovers,but based on your recomm L46 might be the way to go,let me know if you find them at [email protected]

8" is really the sweet spot for a 2-way. 10" woofers can't fill in the hole at the upper midrange as well, and the 034 certainly can't.
I did find the XO's, PM me if you want them.

hello,to update based on my cabinet size and finding some 4401 xovers with adjustable tweeter output(which made all the difference) I hooked up everything and auditioned the speakers with various music while building grill frames to replace the cardboard that was holding some beautiful auburn cloth,i shutter to think of the time wasted on this project. Rd Grimes was right on about the 8" driver with the jbl 34 tweeter,really the only way to go.my tweeters have new diaphrams and after a couple hours really sounded dreamy but the woofers would get muddy,so I ordered new caps and resistors to rebuild xovers,project may never end.
