Truth monitor dead

I have a pair of Behringer B2031 Truth monitors (active) and the tweeter went out on one of them recently. Not sure exactly when but it was probably when they suffered through an obnoxious squeal while powering up my Echo Layla and Behringer ADA8000 - I didn't have the monitors muted.

The monitors are out of warranty.

I ordered a replacement tweeter ($55) and installed it. When I powered up the monitor I heard a nasty crackle and smelled burning petroleum product. Blew that tweeter too. I guess the problem goes deeper than the tweeter.

As I see it, I have two options, neither of which I like. Pack up the bad monitor, pay for shipping to and from a factory-authorized repair facility and pay $95/hour for service, plus parts. I can't imagine this option will cost me less than $200 - probably more. Or I can buy a new set of monitors ($329 and free shipping) and keep the old ones for spare parts. I don't think I can buy a single monitor.

Any other advice? For instance, do the symptoms I describe point to another diagnosis that I might repair?

This is most unfortunate. Any help is appreciated. Thanks.
 
There's the old rule:

Power up monitors last, power monitors off first.

There may be some problem with that particular monitor that requires it to be professionally serviced. It would really be a waste of your money to do that in my opinion. See if you can get one singly, which would be the most affordable option. That might even cost less than having one serviced.

However, this may be a perfect time to upgrade your monitors to something better. I'm not really sure I see any advantage in owning four of those monitors, even for spare parts.
 
ouch......

i feal you, i've seen this mentioned a couple times on the forum.
call them up and tell them they sent you a crappy tweater, or just call up and ask thier advice, i've never called beringer, maby they have good customer service??? i don't know.

BUT........
if you decide to buy a new pair of minitors (i think you should)
DON'T buy more berringers. they are known for this issue.
many other options in the same price range.
 
It's possible that your crossover is malfunctioning by allowing low-frequency signal to your tweeter, and that's what is burning them out. Depending on how complex the crossover is, you may just need a $5 cap and another tweeter.
 
you can get a single speaker. Look around online, some places are priced by a single speaker.
 
notbradsohner, I have looked around for single speaker pricing with no success. I'm trying google with all words "B2031 single" and not "pair". Any other search hints?
 
That's Behringer for you. Unreliability accompanied by poor construction & perf.

Check out some Yorkvilles, Event's, Tannoy, KRK's or Wharfedales.
Behringer=Garbage!
 
Fifty dollars for a tweeter?

Try www.partsexpress.com, I think those B's have two amps per speaker, tweeter and woofer.

Try a car audio place and ask them how much to check and see if an amp is dead. If reasonable, take the tweeter out, but bring it with you, and take your speaker in and have it checked. If its the amp and they don't want to try and fix it for cheap, junk it.

If its fixed, try a cheap tweeter from parts express. If that works for a while try a more expensive tweeter. Then stop.

It is probably a 2 cent part in the amp, but finding someone to fix it, for a reasonable price, hard to do.

Good luck
 
Just for frame of reference, the tweeters in an Event Tria (PS-5) go for $39.... ask me how I know.... :-)

I opted to replace it after a "feedback" incident.... :(
 
I'm thinking thats a soft dome tweeter about 1 inch...

In diameter. Check out parts express or call and talk to a tech and maybe they can match it, next time. They have aout 30 or 40 soft dome tweeters from 6 or 8 makers.

maybe more.

and considering how some peoples minds work (not yours) I have no financial interest in parts express.
 
rstiltskin, thanks much for the advice. I will follow it and post back the results.
 
Glad to, hope it helps, can't find an amp source.....

There are very low parts count amps available up to about 120 watts rms. but I can't find a good source, except for subwoofers. will keep checking.

Heyyyyy, if the B's are bi amped why is not one of the speakers working?

Maybe the power supply is shared by both amps? Maybe in the power supply?

Hmmmmmm......Maybe in the crossover.........I am thinking the crossover will come before the power amps, so the crossover need not handle too much
power. Make sure whoever looks at it is aware that it is biamped (if it is).

I will check back periodically for your post......best of luck.
 
Behringer truth

Get a couple junk full range. Turn gain way down. Power monitors up. Touch leads onto full range Listen!..... Maybe a shorted opamp
 
The tweeters are mounted on the plastic moulded front panel and they would not be easy to replace with a coventional type which you would not want to do even if you could , I would hope.

It sounds like whatever you did when you powered them up damaged the Tweeter amp which is probably giving out a lot of HF which will carry on blowing drivers until it is sorted. I would suggest you contact the Berry agents and get them to repair it.

Get a quote first as it may be cheaper to just buy another pair?

P.S. I hope you found this post slightly more helpful than Mr.Q's :D
 
I called our local music store (Charleston, WV) to see if they could refer me to anyone local. I wasn't expecting much - but there is a guy less than a mile from me that does this sort of work. I will drop off the monitor with him today. I'll keep you posted - thanks for all the help.

This home recording stuff is not easy - the musicianship required is challenge enough, but now that I have acquired a basic knowledge of audio signal processing and how to run my gear, I now have to learn electronics.

On the bright side, it beats giving my money to charity or buying something nice for the wife :p

Wether one likes Behringer or not, you can't blame this particular problem on the manufacturer. You can take $2000 speakers and blow them just as easily by turning equipment on/off while your power-amp/speakers are on. COME ON!
 
I have a pair of Truths also; about 4 years now I think.
I am very happy with them.

If one blew...for the price I would just throw it away and buy another pair! :p
 
The repairman has diagnosed the problem and can repair it, about $125 including parts. Apparently an integrated circuit sending power to the tweeter was fried. He said the tweeter was getting 40V DC. Maybe that means something to you guys.

Still less than buying new monitors, and I am pleased to find a capable repairman within a mile of my house. Pending parts delivery, should be ready in a week. Thanks for everyone's help.
 
Yes!

do you get any kind of warranty on the repairs?. I think you should get 90 days or something. good for you!
