jbl 4320 transformation into jbl 4333/L300

[bluewow]

I want to make a 2 way speaker as the jbl 4320 a 3 way speaker. I will add a tweeter and probably change the woofer.

I have seen a lot of information about the jbl 3133/3133a crossover, but it is almost impossible to get any info about the jbl LX-300 crossover.

Have any of you experience about the jbl LX-300 crossover? Do you have the schematic? The one million question, based in you experience which crossover is preferably/better or superior in audio quality the 3133/3133a or the LX-300?

Is anyone that knows the differences?

Thanks,

Why do an add-on like that instead of just building a full 3133 crossover directly?

I look up LX-300 and got info on this 2 way system?

On a whim, I look up L300 Crossover and got this thread, among others ...
http://www.audioheritage.org/vbullet...L300-Crossover

For what its worth, I built the Giskard 3133 equivalent crossover
http://www.audioheritage.org/vbullet...-circuit/page4
when I moved my 4320 parts into an L200 cabinet and made it a 3 way with 2405 slots ... Tho over time I changed the LE15s for 2234 woofers, and later swapped the LE85s for external smith horns and larger format 2441 drivers.

I've got a whole thread here about my evolution of the 4320s over the last, say, 7 years ...

If you're going to do a new crossover, I would strongly recommend you read Nelson Pass's piece on fixing the L-300 with a new crossover:

Better sound, and it uses available parts - sounds like an easy win/win...
