I have a two way peavey p115 speaker system and audio has stopped coming out of the high frequency driver . I tested the high frequency driver with a multi meter and it is fines.I also have a working speaker i used as a reference and i switched the high frequency driver and i hear audio. What could the problem possible be and what are the next steps i need to take to fix the problem?

Sounds like your speakers may be out of phase. Reverse the connection on ONE speaker (swap the wires connected to one speaker.

Normally on older Peavey amps the grill is on a frame attached to the face held on with velcro. I suspect you have something vibrating against the speaker if it's only one frequency. Once the grill is off it may be apparent.
Also on old Scorpions and Black Widows Peavy has a piece of foam in the hole in the magnet to keep junk from getting in the speaker. Over time it crumbles and opens that hole, but even worse can get it the gap and freeze the voice coil. I always suggest cleaning it out while the speaker is out of the cab.

You will require 4 heavy gauge 1/4" speaker cables in order to connect all 4 cabinets to the Behringer power amp. Usually two longer ones from the power amp to the sub woofer cabs. Then two short ones from the second "thru" jack to the upper 15" cabs. Remember the entire audio frequency range is going to all four speakers. Sometimes you will have problems balancing the low frequency levels between all four cabs depending on the loading of each. A more desirable way to do this is with a bi-amped arrangement. This way two seprate amps are used for the subs and 15" cabs and you control them independantly.

diaphram or crossover..

Try connecting them to another amplifier...you can use the speaker output of a guitar amp as a quick test. If the amp (and mixer) check OK, it sounds like you are about to become good friends with your local speaker reconing shop.

Remember...Distorted Audio Can Kill Speakers even at low volumes. It happens because sine waves become square waves. Google it for additional information.

Peavey uses a protection network and sometimes it gets blown when too much power is sent to the speaker. The speaker may be blown however. Peak power for this is 800 Watts and 400 Program... That is NOT RMS power. Make sure your amp is no bigger than 300 Watts RMS driving this. If you are REAL lucky, maybe a lead has fallen off the speaker... Open the unit inspect and test the components.

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.

i) I believe you can access the fuse by removing the Input Jack Panel.

ii) If fuse is OK, then unscrew the horn unit, take off one speaker wire & measure resistance. If it is open circuit then you can order a replacement horn diaphragm (if you feel confident to fit it to the horn).

Troubleshooting is always a "process of elimination." Have you tried hooking up your Peavey powered mixer to another set of speakers? How about connecting the speakers to another audio system? Your term "very little sound" could mean audio input problems, mixer/amp settings or failure and possibly speaker damage (internal passive crossovers). Please be more specific.
