4430 crossovers

[Figge]

ok as some know im gonna change my old 2421A diaphragms. and becouse of JBL:s insane price on these i aint doin´it!

i know the newer 4430:s use 2425/6:s so i´ll get some of these intead.

The question: can i swap these without any problems? were there canges in the crossover also on these 4430:s?

early 4430 use 3134
late 4430 use 61449P

does this mean im in trouble? or are they the same?

Swap away there were no changes and JBL used 2421's 2425's and 2426's

hi rob! this was what i suspected...but u never know!

i also dug up the info on 4435 they used the 3135 network only.

so what the hell is 61449P? some JBL info mixup?

Nope, JBL switched to a different method of assigning model numbers. For instance, a 2245H is now a 60513X.

61449P should be stamped on the PC board.

Hey Figge!

I was searching the 4425 network called 65934-00

Finally I found out that it simply is the 3124 (thanks to this great place)

JBL seems to like switching numbers

I think it might have something to do with computers. Maybe "3124" or "2242H" don't get along with software programs?
