Jbl 4325

[mazen0822]

hello all,

first time, long time. I just picked up a pair of 4325's for a steal. they sound amazing and love them. I'm coming from a pair of 4412's so the sound is completely diffrent. but best of all they came with some additional parts. the seller gave them to me with a pair of 2402h-5 and 3133a crossover as well. now id love to install them all and turn them into a 4333. first off does anyone know if a 2312 will fit in that cabinet before I get to far ahead of myself.

here's a list of what was in the cabinet and given to me
2402h-5 not installed
2216
2420
2307
3122
3133a not installed

Congratulations the model 4325 is rare, it’s a 4320 with a different woofer
It seems interesting to add the 2405 tweeter

ill get pics up when I get back home, im out of town for a few more days. I also picked up some goodies from our friend Lee in Montreal.

[mazen0822]

need some help, im trying to hook up the 3133a crossover and im not sure what color wires go where. the schematics I found show different color wires then I have. ive got green, white and yellow. im assuming the green is the LF but not sure which the yellow and whites are. I think the white is MF and yellow is HF. can anyone confirm please. ive searched but can't find the answer.

Interesting find. I'm thinking that a 2402H-5 is a 2402 "bullet" tweeter with the 2405 "slot" diaphragm to remove some "peakiness" and extend a bit higher. There may be minor changes to the phase plug for the different diaphragm. If they still have original diaphragms, if I'm not mistaken, it is a nice and fairly rare find.

Hello Mazen, you are correct in your assumption. Green LF, White mid, Yellow high. Also the white wire with black trace will be wired to the positive post. Proper connection for phasing on that crossover. Hope this helps and good luck with your find

An RTA, or sweep program, can tell if it a 2402 or 2405, or aftermarket diaphragm without opening it up as the various spectra are fairly well documented.

so it looks like its time to rebuild my crossover. the MF and HF on one speaker are no longer working. does anyone have anyone in SoCal that they could recommend on doing this. this is unfortunately well beyond my skill set.

If you are using the 3133 crossover the Lpads could be dirty. At a low volume level turn the knobs back and forth a couple of times. If they do not move chances are they have been over powered and burnt.

Or many, many times, quickly. But I'd just leave the volume off, or the whole system off, while twisting the knobs. You could get some snap, crackle, or pops.

At any rate, if a 3133a, I'd be inclined to suspect the biamp switch (particularly if both MF and HF are 'out'). They're notorious for this.
I have to give my 4430 switch a jiggle now and then (similar switch arrangement).

Depending on where in SoCal you are, I might be able to get you started. Feel free to DM.
