If you keep losing high end drivers it is because you are using an amplifier that does not put out enough power (thus clipping the signal and creating a very large amount of high frequency harmonics that overpower the drivers), or too much power for them, or you are adjusting equalization from behind them so that they sound good to you, in which case you are again overloading them. Highs are very directional so to adjust them properly you have to listen from in front of them. Another possibility is that they simply cannot handle the power you need to fill the listening area adequately.

Have 2 jbl 615 get good base and sub but neither tweeter playing


You will need to determine if it's the amplifiers or the tweeter themselves that are not working. If you open up the cabinets and check each tweeter with an ohm meter for continuity it will show if the tweeters are working, in which case the amp is the problem. if the meter shows that the tweeters are blown, you should still hook up another tweeter or speaker to the horn amp to see if it's blown and therefor took out the tweeters.
If any of this sounds complicated, you'd be best off taking the cabinets to the repair shop.

I lost the treble on both Alesis Monitor 1 speakers. The treble is good on the amp output toward the speakers. I'm thinking they went out one at a time and I didn't realize it until I lost the...


It's probably blown tweeters. But if you want to spend the money on a hipshot guess, try to find the the crossovers somewhere first; then find the readily available tweeters if/when that doesn't work out. Google "alesis monitor one MK2 tweeter".

You could test the tweeters by just removing one non-functional tweeter and wiring it directly to the speaker leads and with REALLY LOW volume containing NO BASS see if it makes any sound, which would prove it does/does not work.

Going forward, if the speakers sound stressed at high volume - THEY ARE. Too much power or too much distortion (overdriven amplifier) will kill speakers.

I recently installed some Audiopipe CRX-203 2 way crossover in my car along with some *** Tweeters ... the driver side works fine but the passenger side tweeter keeps burning out and gettin really hot....


Is it possible that the polarity of the tweeter is backward? Also, you may just have a defective tweeter. If it's heating up, it sounds like it may be bad.

Just bought second hand Mercury MX4-M in visibly good condition. Very little dust visible on cabinet and cones behind the grills. On closer inspection I can see one of the tweeters have oily substance...


The oily coating you see is a damping compound applied by the company to make the sound smooth and less edgy or harsh.Cheaper speakers most of the time sound bright and progressing on to a Hi Fi speakers take time getting used to.In the long run you will realize you will get lesser ear fatigue listening to good Hi Fi speakers .
One test to confirm if the tweeters are working all right is to play a blank FM channel with the FM mute released ( FM mode on Mono ). Turn up the Amplifier volume and you will hear a loud hiss ( like standing next to a waterfall ). Turn the balance control towards each speaker and see if they sound identical.
Next remove the grill and cup the dome tweeter with your hand with out touching the dome itself to block the hi frequency sound, it should sound dull. And when you remove your hand should sound hissy and sharp.Try to do this with the balance control turned towards your speaker.
Sound is very subjective and personnel like taste, don't let anybody talk you into deciding which is better for you.

This is a BI-AMP powered speakers setup, the power amp for the woofer is still working but either the high frequency power amp for the tweeter is blown or the tweeter speaker is blown, you will need to use an Ohm meter to check the tweeter and the fuse in the high frequency amp.

I was doing a party iconnect the mic to mixer, they star to talk paralell with music and blow the upper part of speakers, they sound but not any treble


Hi,
What happened is that the tweeter is blown. or a fuse in the speaker that goes to the tweeter has blown. Hopefully that is it.
There are several causes. Here is the theory so you understand how to match an amplifier to a speaker system.
Tweeters have a much lower capacity for amplifier power then woofers do. All professional speakers as well as home speakers reflect this.
You may ask exactly what blew the tweeter?
Usually what destroys the tweeter is not amplifier power but distortion. If someone is overloading the microphone, or the microphone is not trimmed to the mixer. You get distortion. This distortion is what caused the tweeter to blow. The signal must be clean. If you put too much power in, it may survive OK but if you put distortion in, it will more likely blow.
It is no shame for this to happen. I have had it happen to me when mixing a live show. You just have to watch what is happening and not turn things up too loud so the mixer or the amplifier distorts.
Also when doing sound work, the ears of an engineer naturally lower the perception of loudness. Engineers often keep turning up the equipment up more and more during a performance because they have lost the perception of loudness that was there when they started. That is also the reason that many professional studio musicians and drummers loose much of their hearing at an early age.
Hope this helps,
Happy New Year,
Mark

No sound out of tweeters, highs out of woofers?


it does sound like you shorted out your crossover which can be fixed if you know what you are doing, but in the long run i would try to get another one i know that raidoshack sells some small ones and is also cheap, if your positive that you didnt short out the crossover se if it needs power, see if you can cross your woffers and tweeters on the crossover, if not is there any settings that u can change on the crossover? hope i helped :)

The tweeters are probably blown, i had the same problem.
You can test this by placing the cable on the dismanteled crossover at the back of the speaker. colour blue/yellow.
No high volume please.
See http://www.hometheatershack.com/forums/diy-speakers/4549-wharfedale-modus-one-six-crossover-pics.html
for pictures.
If the tweeter is blown it can be dismanteld with the aid of a screwdriver, horizontally.
Place it between the tweeterbowl and the ring which has the mark wharfedale on it. The tweeter comes loose. On second hand sites you can buy little speakers, like modus one or two's with the same tweeters for a good price and put them on your larger speakers.

This how i repaired 2 of my 4 modus eights.

good luck Danny Mol
