B-52's website:

yea really not a lot to go off of tbh
you could try hitting b52 up for a service manual if they have em, but again doubtful
like i said you seem like you're over your head on this one

what else would you need to know?

electronics

so its not as simple as matching basic specs?

this wouldn't work? http://www.parts-express.com/pe/showdet ... er=290-634

no there's a bit more to it...

any good sites to learn from?

uhh, a crackle probably means u ripped something in the speaker woofer itself. Its probably only when something loud goes right? I've fixed speakers using household glue that were blown out, u just have to pull the speaker out of the cab and inspect it thoroughly. The last one I fixed had the webbing around the base of the woofer loose , probably from someone blasting it too loud. It would rattle on heavy bass notes, which was from the webbing being loose. I simply glued all around that webbing and let it sit a day to dry, and now it works perfectly.

get whatcha pay for

but if all you need is a new surround for the sub, then consider yourself lucky. That's probably easier for you than the electronics .

I think I've narrowed it down to the electronics.
Its the horn on one of the tops thats causing me trouble. It works fine when plugged into the other top.

maybe this will help..

^that is the specs for the horn driver!
the 12" woofer has no labeling on it so I can't tell its specs!
.. is this the kind of information you're looking for?
basically what specs do you need to know?


also I contacted the closest authorized B-52 repair shop and they said they could special order it for me.. $40+ shipping!
should I just do that?
Thanks!

Well these guys are making it seem harder than it really is and trying to just give you a hard time, which is what assholes usually do. It sounds like you narrowed it down to a blown out horn. To make sure, swap both speaker channels, so left is right and right is left, then see if the same crackling noise is in the other speaker. With that you can narrow it down to either your amplifier is the problem or your speakers. Most likely its just a blown out horn in the speaker and not the amplifier, so you can either attempt to repair the horn, which only works in some cases or order a replacement and put it in yourself. You'll only need basic soldering skills to do it and cant really screw anything up unless you accidently burn the speaker with the soldering iron or something like that. Its as simple as taking out the old horn and putting in the new one

Thanks for the reply!
I tested both horns and they work great.. so It has to be somewhere in the board! I was able to contact B-52 and they're sending me a new crossover for $37!

I think it's more likely to be the amp than the crossover. Is it biamped or does the crossover come after the amp?

Hmmm.. The amp is in the sub right? Then it goes to the crossovers then drivers?

looks like the amp is in the sub from the manual. Yah the way it works is, your signal coming from your amplifier goes into your crossover which roughly divides the frequencies up so that your low end goes to the woofer and the high end to your horns/tweeters.

What was the result from swapping channels? Crackling stay in the same speaker?
And how did you test out the horns?

the horns didn't need any soldering so I just swapped it with the one on the working cab, and it worked fine..

alright. It sounds like you isolated it down to the crossover or the wiring inside the speaker. You could take the good crossover from the other speaker and try putting it in to see if the problem disappears. If it does, then just order that one u found.

Did you end up fixing this?

yep!
new crossover did the trick!
I just emailed B-52.. and they shipped me the part.. i think it was $40-50 shipped.

Good to hear!

How are you finding the set up? Can it handle some bassweight? Ive been tossing up buying or building a system..... eventually
