Had a great show last night - all sounding GREAT , about 1am a group of girls come over and ask for some Dance Music - Since Karaoke was done I thought while I tear down to accomodate the request...   I put on some BASS heavy Hip hop and crank the volume.......   OH OH

Halfway the the song it started to sound like an old AM radio ..BASS Was gone and it seems jut like the tweeters are working ON BOTH SPEAKERS.

Tested the speakers again this morning and same results --there are no fuses or anything on the speakers themselves ...They were light weight 12" and i think I oushed them too hard....THOUGHTS

That would be my guess that the low frequency drivers are blown.  Just out of curiosity what would was the make/model of speaker & amp - I know you've stated it before but I can't remember.  My guess would be that the amp was underpowered for the program rating of the speaker & it was being driven into clipping heating up the voice coil on the drivers.  12" cabs should really be used with subs IMO!  This helps alleviate problems like this & allows the sub to take the bass instead of the main tops.

Lon

I tried to get away using 12" speakers when I should have used my heavier 15's

Behringer B212 with a Crown XLS602D ---Is that a mis match ?
I think I fried them good I actually smelled something burning  :(  :shock:

I don't use any "limiters " etc in my chain---Is there something I should use that would prevent this in the future--BESIDES BUYING BETTER SPEAKERS which I might just have to do ----

At $149 each....I dont think they are worth fixing ..although I am contacting Behinrger Monday to see about any warranty fix

They might just replace one -- did you blow both, though?

If you were maxing that amp in a stereo setup, it is 380W into a 600W speaker. Dangerous on a bass-heavy signal, IMHO.

Actually that amp is SLIGHTLY overpowered for those particular speakers.  They need 250 watts @ 8 ohms, the amp pushes 380 into 8  ohms.  So you were actually over driving them.  Still the 12" isn't designed for the heavy bass at all.

Once again....

If you would use better equpimnet you'd not have this problem.


I will make you a deal.

I will sell you my old JBL system and meet you 1/2 way in Breezewood for $1000.

All passive. You will just need a second Power amp and cross over. Your Crown XLS 602 is perfect for the tops it's what I ran for years.

I have 2 JBL Eon 1500 and 2 JBL JRX 100 18" I just reloaded the 18"s with 1000 watt Black Widows less than a month ago.

The System will pound the daylights out of any bar. I ran an RMX 4050HD on the subs. It's les than 6 months old if you want a Sub amp I will part with it for $900 for a total of $1900 and throw in a free SKB Rack.

LYQ-  Thank you for your offer...I think

You may be right that more expensive speakers would not have blown--but I take the blame on this one --I was pushing the speakers to do something they were not intended to do ---(play bass heavy hip hop)   :(

I still need a pair of 12" for small gigs ---I might fo back to the PEAVEY pr12?

Lonn
My powered mixer is pushing 165W x 2  at 8ohms  Is this a better AMP for the small speakers ????---I'll be shopping today --might have to buy a small mixer/amp combo to use with the 12"

Thank for suggestions

Go to the Carvin website. they have a 12" speaker with a molded cabinet for like $200, LM12. The LM15 is $300. You won't blow them. Yamaha or Peavey you wouldn't have blown. The Peavey PR12 is under $200 and the PR15 is $199. The Peavey PV115 is a nice speaker too-only $219, but it's big and heavy and lacking in bass. The Yamaha BR series are very good too.

The EV ZXI is $285 each brand new and they kick a$$. They are very small and light, you would love them. Add a sub or two and you have a great small venue, super portable system. Go to Sam Ash and ask to hear the ZX1 speakers, it will blow your mind. One of the best deals in the $300 range is the Yamaha S115V, but they are heavy. They sound fabulous and are 500W program and 1000W peak, you won't blow them, EVER. The sound is rich and full, the highs are nice and crisp and clear. They are fabulous, but heavy.

I can vouch for the Yamahas S115V - they are incredibly strong. We have a pair of the 15's with a set of subs to go with them and the sound is very, very good.  Yes, they are heavy, though.  Price on the Yamahas hasn't varied much over the years - I purchased mine in 1998 and they got a good 5 years of use 4-5 times a week, daisy chained to a pair of 15-inch Bag Ends. Can't beat the sound, a lot of speaker for the buck.

Your problem wasn't too *much* amp, it was too little amp pushed too hard. DC will blow any speaker.

What you really want is an amp match with the speaker. That way if you keep your mix at 0Db or less, and you set the amplifier to max power, you can't really blow the speakers. I run my amp at near maximum output level, and allow the main faders to control the setting.

Any speaker will blow if you mistreat it. I have heard of Yamahas, Peaveys, and JBLs blowing. This is actually one of the attractions of a powered speaker, they are hard to blow as long as you mix the input even a bit properly. With a limiter circuit, they are near-indestructible.

I am sure there were those who will blame Behringer, but their pet speaker has blown too, betcha.

One other choice if you are a Behringer fan. B212A is an active speaker with a 12 inch LF speaker, molded cabinet so it's light, $229 at zsounds. The 15" version is only $50 more per speaker. You won't blow them because they have the amp built in. Hard to beat those prices and they're very decent sounding speakers.

I agree with the reviews on the Yamaha S15V Club series- I had 2 of them for a few years and LOVED THEM.  I have 2 15" full range speakers I use now and always liked to have 2 12" liteweights for small DJ type gigs.   I am seriously considering  buying 2 more Yamaha S15V and forget about the 12"  ( I don't use a sub).
The 61 lbs is the factor --They are heavy bastards  LOL

Too much amp can blow a speaker just as much as too little amp.  The amp he has is overrated for the particuar speakers program rating by over 100 watts - not a huge factor & yes a better speaker probably would have taken the abuse better.  But overpowering a speaker can - even if the mix is running at 0db, if the amp is sending more than the speaker rating - even a clean signal - it can go too.

I blew my Peavey 18" Black Widow, BUT I also only had a 400 watt amp pushing it.  I replaced & bought an amp that pushed the proper power of 1000 watts @ 4 ohms.  All is good now.....

No blame here, it was the wrong amp for the particualr speaker & a speaker that was too small to play what he was trying to do that night.

Just because the amp is built in doesn't mean they can't blow.  The wrong mix - like mentioned above from mcky - can blow any speaker.  I've seen a good share of powered speakers blow out.

Good point, I probably should have said that it was a lot less likely that he would blow them since the amp and speaker are matched by the manufacturer to provide the proper power for most usage. Abuse is abuse. Accidents can happen and especially when you're tired.

If you really want 12' Speakers.

I suggest Turbosound TXD-121. 600 watts program they outperform most 15" speakers. I power mine with a QSC PLX 1804 or 3602..

If you look hard on the net you can find a pair for under $1000.

I'm not sure, but I don't think he wants to spend that kind of money.

Wow Stogie, a Carvin man, I'm impressed, been using Carvin gear for years, my favorite cabinet was the 1584's, I was sorry to hear that they've discontinued them, purchased my first pair around 1985.

There are multiple ways to blow speakers, either way from my experience I'd never trust a 12-inch low end to handle anything in public, if you're being paid that is.  There are many compact 15 inch speakers, look around and find a pair that's light enough and suits your needs.  Behringer may not be the best in the market but that's just my opinion.  They make quality mixing boards but not that reliable with all their other gear.

Just my 2-cents, I have tried to do sound in small places with 12-inch lows and never could get it right, 15 is the way to go or look for more problems.
