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.

Tweeter no sound but speaker no problem


In the most general, basic sense, I would be assuming that this is just one speaker and not 2 with this problem, or 3 or more.
Only way to get the ball rolling is pull the tweeter from the cabinet, checking to make sure all wires are connected at the tweeter and inside the speaker.
If that is the case, then you would need to determine if this is the tweeters fault, or its crossover (thing that divides the sound into whats right for the woofer and what the tweeter wants).
If you have a multi-meter, you would disconnect the wires from the tweeter, set the meter to ohms and touch a probe to each speaker terminal. No action means burned out tweeter, 100% action means burned out tweeter, a reading slightly less than the rating on the back of the tweeter (for instance an 8 ohm tweeter would show anywhere from 6 to 8 ohms on the meter) means tweeter is good.
If you have no meter then take the tweeter from the good speaker and swap in place of the bad one, making sure you respect + and - connections.Its a little risky this way,since if there is something wrong in the speaker it may hurt the good tweeter..(the meter is the safer bet). If it works, then you need a replacement tweeter, if not the problem is either wire connections inside the speaker, or something is wrong with the crossover.

The amplifier keeps burning the tweeters in the speakers after replacement


Please check the wattage of the replaced speakers, now check the cross over in the speakers, if the capacitors are short the voltage might flow into the tweeter coils to burnt them out. Also you can try and reduce the high frequency and also see if the tweeters heat up . If so use high wattage super cooled tweeters.
Check finally for fault in the amplifier output- high voltage/current.

How do i tell if my problem if the high freq diaphram or the cross over


The crossovers in professional speakers don't fail that easily. It could be a blown tweeter. To confirm remove the metal grille-- remove the screws of the Horn Tweeter -- remove the cable connectors on the tweeter terminals ( Red and Black wire ). Now if you have a multimeter put it in Ohms range and touch the probes on the tweeter terminals-- It should show a reading betwwen 4 to 8 Ohms depending what is written on the back of the tweeter magnet. If you do not have a Multimeter you can take an ordinary cell/battery ( 1.5v ) from a TV remote and touch the terminals of the Horn Tweeter with the battery. + to the tweeter + ( a small red dot or mark will be there on the tweeter ) and -- to the tweeter -- . When you touch the terminals or give 1.5 volt supply the tweeter will make a scratching noise.
If you do not hear the scratching noise - it indicates a blown tweeter coil and will need replacement.See link below for spares:-

But if it does, you are in trouble and will need professional help from a electronic technician.
Could be blown HF Amplifier, suspect the crossover last. They seldom fail.

I need installation manual


its not a subwoofer it is a midrange speaker. all you do is connect your outputs from the radio to the crossover then connect both the tweeter and midrange to the outputs on the crossover. it is called a component set.

Audiotek amplifier RMS


the usual RMS of and amp UNBRIDGED is 1/4 or the max so 1200watt max would be 300 watt RMS and a 1000 would be 250 WRMS

Need to replace 11L tweeter


the best solution I've found is this:
1. Remove all the tweeter screws.
2. Take a thing metal rod (a coat hanger should work) and lightly tap the tweeter through the top port in the rear until it is loosened and comes out. The tweeter is totally sealed so you probably won't damage it if you need to do this to a working tweeter.

This method also works for the woofer but you need to be very careful to tap the frame or magnet of the woofer and not the cone.
