The tweeters seem to work but distorted at audible volumes. The horn and woofer don't work. Is this a crossover issue?

The tweeter is working but the 15 inch horn is not working. What could be the problem.


It is called a 'tweeter' not a Twitter. I have recategorized from the social media site Twitter, to Speakers.

could be three things

The crossover unit has failed

the woofer is blown

there is loose wiring either to it or in the windings.

Peavey problems


I assume you mean the Pr-12RX passive? That seems wrong to me, too. Put an ohm meter across the terminals of the horn driver and the woofer seperatly to see which, if either, is blown. If they're OK, look for a bad solder joint on the crossover.

Subwoofer makes noise like an untuned TV regardless of volume knob


I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

If all speakers except some of the super tweeters in my gem sound tr-150 cabinet aren't working, could it be the crossover network that they appear to be all wired to, is no good, or do you think all...


Did you actually mean "all speakers... AREN'T working" except some tweeters? Crossovers don't protect the woofers. If crossover die all speakers they protect go silent due to loss of signal. Excess volume or distortion kills speakers and not always linearly.

If you said it wrong and some tweeters work, I'd suspect the latter above...

You (or we) could guess or you could take out one tweeter at a time and swap it with a (presumed) working one or just emasure it for dead short or open with an ohmmeter. If the tweeters check out and work elsewhere the problem would likely be within the cabinet.

Both tweeters on one of my Bose 301V speakers have stopped working. Is it possible that they failed together or is it likely to be a crossover problem?


Since there is no single crossover for two speakers it is likely both speakers experienced the same audio trauma and blew together. Something like microphone feedback will take thenm out in a literal heartbeat.

The 301's sometimes have an element in series with the tweeters that looks like a little light bulb (or it could be a fuse, too) and it is designed to blow before the tweeters die. They're easy to find if you remove the woofer to get some maneuvering space inside. If they'rethere and blown (visible) you can either wire aroundthem and be careful in the future or get some more.

Do a web search for "tweeter protection fuse".

If the tweeters did take the hit get on eBay and find some more, plus think about installing protectors if you can't avoid excessive distortion or power going to them.

Regarding pwoer vs distortion, the latter will kill tweeters in a blink so don't think a modest amp is safer than a powerful one. The modest amp will distort sooner.

The top part of the mackie speaker isnt working. all that is working is the big bottom part, and the sound sounds like the bass is the only thing coming out.


The typical cause of this is a blown tweeter or the tweeter has broken off of the horn and fallen inside the cabinet. Remove the screws from the horn and carefully remove the assembly. Try the speaker at low volumes to see if you hear any sound at all. Next, remove one of the wires and using a 9Volt battery quickly touch the 2 leads on the tweeter. If you don't hear a click, the tweeter needs to be replaced. Contact Mackie service for a replacement.

If you hear a click, then the problem is in the crossover or amp and further investigation willbe required.

I have a couple active phobic loud speakers, one is completely out of commission and won't play anything. The other will play sound but only through the tweeter, while the speaker itself does nothing. I...


The tweeter is working but the woofer driver isn't which will change the impedance (ac resistance) of your amplifier output. The other speaker isn't working which will again, change the impedance even more. This could eventually damage the I.C. amps should you apply too much volume to the speakers.
You can turn the volume up to normal listening level and with your finger, slightly press the cone on the woofer in and out a couple of time. Does it engage in sound when you do this? If so, the woofer's coil is damaged and the woofer must be replaced. No sound? Open up the speaker (stereo off) and make sure both wires are fully secured to the woofer. Should they be attached securely, your woofer is probably defective. Should you have a crossover network, you can obtain a good, known working woof and temporarily wire it where the old woofer goes, turn on your stereo (minimal volume) which can verify the network pcb (crossover) is working.

I need replacement crossover because they got burn


The crossover in these is very simple and if it is burned, likely your speakers, maybe both, the woofer and tweeter have been damaged and need to be replaced. Test the speakers before changing the crossover. You MAY NOT notice the damage until you start driving the speakers again. The voice coil of the woofer is a common thing to fry, and while it may not open up, often it becomes unbonded to the coil form and rubs the magnet pole pieces. The tweeter/horn often wipes out the diaphram or blows the element open. Some of these are piezo horns and they can sometimes survive. These are rated at 100 Watts and if your amp can deliver over 50 watts you have to be careful to not put too much power into these. I have several of the Kustom 10 inch ones and several of the 15 inch ones... Also I have two 15 double stacks and they all seem to use the same crossover. Believe me, the crossover is far from what I would call "special" like the advertisements say. As an electrical engineer I was very disappointed. Anyway, test your speakers as they may be the worst of the problem.

How do i wire the crossover on the dxd210/213


If the crossover is made to accept speaker level input from amp then.....Amp/head spkr output + to crossover + input. Amp/head spkr output - to crossover - input. Crossover midbass + out to midbass spkr + input. Crossover midbass - out to midbass spkr - input. Crossover vari-tweeter + out to tweeter spkr + input. Crossover vari-tweeter -3 or -0 or -6 out to tweeter spkr - input. You have to choose for your preference. 0db makes the tweeter respond normally. -3db mean 3db lower in volume...and -6 means 6db lower in volume. Choose based on your liking.

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 :)
