This is my first posting with this group however I've been reading
other postings for several years now. Lots of great advice and
knowlegeable people here.
I just bought 2 new Behringer B1520 PRO loudspeakers from a local
vendor (Detroit area) and immediatly on the first job I used them on, I
burnt the diaphragm on one of them. My question is; is there a non
behringer diaphragm available for this driver?
BTW-When I got these cabinets and tested them, one did not work at all.
I found that speakon on the cabinet was not soldered to the crossover.
Interesting QC in this case!
Thanks,
Blake
Take advantage of Behringers new warranty replacement policy. take
them back and get them replaced and the dealer will ship the bad ones
back to Behringer.

No warranty program protects against user "stupidity". In the case of
the burnt diaprhragm, I may have done that. A long story short, my
spx 900 freaked out and sent out a pure square wave, the rest is
history.
George, with you having 16 of them so far can I assume that you find
them satisfactory thus far? I was very impressed with the over all
performance on the 1520 PROs when you take into consideration the price
I paid. I'm wondering if you have any B1800 PROs and if so, what do
you think?

Have you removed and inspected it?
BTW
Behringer claim the horn driver is electronically protected from such
damage.
Could be the protection device ( a lamp ?) has failed.

Behringer don't make drivers. The diaphram will be from whoever makes the
driver, and it would be a crap idea to attempt to use anything else.
However that it is burnt out implies a bit of a problem elsewhere in your
system.

Was it meant to be, ie not 'cabled' ?

I think the behringer monitors are the best under 1000$ box out there and at
200$ each you can buy a whole rig for the price of one jbl
I don't have any 1800s yet but by fall I will be outfitting a high energy
rock club with a 100% behringer system
including the 1800s
simply every thing behriger I have used in the last 4 years has be such
exceptional values that I am now heavily invested in behringer from digital
mixers /deq rocessors 25oo amps to 1520 and 1220 speakers
the reliability is outstanding
the ability to finally POCKET (serious)money doing sound is a welcome change

that any second source will be cheaper.
See my other posts, the OP's concerns could easily be a phurphy.

Yeah, the speakon is supposed to be soldered to the PBC which holds the
crossover network.
Yes, the lamp did also fail, it's rated for 24volts/75watts. Actually
75watts seems kinda high to me but that's what they have in there.
In the US such items became know as "Monday specials." Workers would party
all weekend and come in on Monday in not the best of shape. for years back
in the 50's and 60's people would check the date vehicles were built and not
buy one built on Monday.
I still tend to avoid vehicles built in the first year of a model change.
Figure give them a year or two to get the bugs out. I know cars are off
topic here, but hey- production lines are production lines. Speakers are not
assembled by people with degrees- at least not usually.
24 volts however is not very high. Bear in mind you gotta have volts and
current to have watts. As the volts go up the bulb will be operating at
more and more of a load condition. Without looking at the entire circuit I
don't know what the engineer had in mind.
I'll say.
My 1220pro's on monitor duty are fantastic. ordered another 3 pairs
yesterday. take me up to 16 boxes.
Price went up recently but still fantastic value.
I've not got any of the subs. i dont intend buying any either.
this is NOT a complaint or anything agaisnt them its just i use the
1220pro's as monitors so need no subs. I have other subs with other tops for
small applications. and if i were to use the 1220pro's as FOH cabs i'd be
using them on their own not with subs.

It's simply a matter of consistancy through a production run. I only
expect so much however when you spend $150.00 per speaker.
Like I said before, I'm extremely impressed with the sonic
characteristics of these cabinets (B1520 PRO) for the money, they are
great.

Since the protection device failed to do its *advertised* job, you have the
basis of a warranty claim.

Hi Blake. I missed your original post, but I got enough from the follow-ups
to get the gist.
I can't tell if this is a warranty matter or not, but I can certainly help
to get that evaluated and the speaker(s) repaired for you. If the halogen
bulb burnt out, the unit might have been seeing some square input signal for
awhile before it failed. I can't be sure without looking, though. Rest
assured, however, that even a non-warranty repair is quite inexpensive on
these units.
Please drop me a line at the office using my contact information below.
We'll get those monitors checked out and running again in no time.

Thanks for the response.
Yep you are correct, they did get a pretty nasty square wave for some
lenght of time. An outboard effects processor went nuts and you can
pretty much guess what happened next.
I actually have a replacement unit on the way for the one that was a
factory defect (open resistor).
an email was sent from my local dealer to a Behringer representative
for a replacement diaphragm monday of last week but the dealer tells me
that he has not had a response to the email as of yet.
If I don't hear from Behringer by the end of the week I will contact
you.
Thanks!

No disrespect to Behringer, but do not buy any subs until you have tried
Yorkville LS808's. Do not power a pair of them off one amp bridged though.
Power each with a Behringer EP1500 bridged, or a pair with a Yorkville
AP4040 in stereo mode. If driven right, LS808's are punchy bastards that
smoke JBL direct radiating subs, so I can't imagine how Behringer's direct
radiating offerings could possibly compete.
