blown tweeter on monitor?

[XxSicRokerxX]

i still have yet to buy the correct power amp for the new used monitors i bought from a random.

I'm considering just tossing these monitors since they are passive and buying actives plus everyone on this forum thinks i should get actives.
But before i put them up for sell or buy a power amp i decided to hear them so i connected them to a standard KENWOOD receiver and it sounded really bad. So i tried connected them to a typical stereo head and once again there were no HIGHS just LOWS.

Then i listened closely and i couldnt hear the tweeter (top speaker).

Is this because im not using the correct power amp? Or is the tweeter blown? Both of them. If thats the case i might as well toss them and not sell them. Or is it because is it because its being powered by a home theater receiver?

If you don't hear anything through the tweeters then they could be blown. You could remove the tweeter from the speaker cabinet and test it with a battery. Take a 1.5V battery and connect some short wire to both ends. Then touch those wires against the terminals of the tweeter, you should hear a click noise.

Are you sure the Kenwood receiver doesn't have the treble on "0" or some electronic crossover set? I would try the receiver with some other speakers just to rule that out as the problem.

Either they are blown, if the speaker has an internal crossover it could be bad, or the speaker wire could be unhooked/severed on the inside of the enclosure. Pop it open, check the connections, and as already said you can check if the tweeter is blown by connecting the pos and neg leads to a 9v battery and you should hear a "pop" if the tweeter works.

Yes on the kenwood receiver i boosted the treble all the way up and lowered the bass.And yes i put other basic stereos speakers on the receiver and the highs worked fine. Anyways on the back of the monitors there is a HI FI and LO FI with a bridge plate (optional) if you wanted to connect them all at once. I tried both methods, i removed the bridge and connected the speaker wire directly to the hi fi so in theory only the tweeter would work. But there was no luck, i connected it to the bottem low fi and the sound worked find but of courses it sounded really low and awful. Can it be because im not using the correct power amp? or it should still work regardless with the receiver im using?

I just looked up the specs on those monitors and they are biamped - you need one amp channel to power the lows and one amp channel to power the highs. So basically you need two amps to power them.

Regardless, the tweeter should still work when connected to an amp, and maybe the bridge plate is not working properly for powering them with a single amp channel... there's all kinds of stuff that could be wrong with them

so i removed the tweeter conected the + and - to the correct terminals on the battery and to my surprise it did not pop. I tried the same with the LO-FI speaker and it did pop. So basically i concluded the the tweeter is not working. I removed a few screws from the tweeter and to make a long story short there were 2 wires literally the size of a hair (single strand of copper wire) that for whatever reason were not connecting to the tweeters + and - posts. I soldered a single strand of copper wire attaching to the the shorter line and to my amazement once i connected the battery it worked! so i put everything back together and its functioning just fine with the kenwood receiver. Thanks guys for the suggestions. Im just going to sell these hopefully for 80$ and save and buy myself something actually worthy. Thank you guys this thread is officially resolved.
