Connect JVC MX-GT88 speakers to a differant reciever

If it has a bi-amp, you can connect the speakers to it. By the amplifier, if it's a stereo with bi-amp, be sure that it has at least 400 watts and up in order for the speakers to turn out great, if a receiver like a integrated amplifier, it may have like 2-10 connections, you can connect the speakers all together if it has more than 3 connections, if below 3, you may need to take the speakers apart and make it 3 way by connecting one wire to the tweeter, another wire from the tweeter to the main or mid speaker then one more wire from the main or mid speaker to the sub.

No bass

If you hear a very high pitch hissing sound coming out from one channel then probably your amp final is gone, in that case you will need to work at component level to fix it

Do these speakers work better with an amp? I am playing them now and they sound muffled using a regular shelf system

No models given, so a guess is what you get.

If your shelf system is not producing sufficient clean audio power you'll get distortion, which can kill a speaker faster than excessive clean power. Muffling is something else altogether. Are the tweeters working?

Can't get wharfedale melton 2 tweeter to work. Looked inside cabinet and need advice on internal wiring please. These are very old but one works perfectly and the 12'' bass driver on the problem speaker is...

The tweeter has burned out and cannot be salvaged. I also own a pair of (ex) Melton 2s. In the beginning Wharfedale were good at supplying spares (see for contact info and advice). A few years ago after my cat destroyed the 12 inch unit in one, i invested in new insides, including state of the art 12 inch woofers, 4 inch mid range and 1inch tweeters with a good 3 way crossover. The cabinet is great so consider asking a techie friend to do this for you. Please don't just cut out and connect to amp speaker wires! You will get terrible sound and risk ruining both amp and speakers! Best regards Karl (

Sound quality bad i can hear bass but really no treble or mids

Could be that those speaker components (mid-range spkr., tweeter) are blown. Try hooking up a similar type speaker and see what happens.

All the electronic parts you can see inside the speaker (usually capacitors, coils and resistors) are responsible for breaking the full audio band (bass - middle - treble) in parts (2 for your case) and feed each part to the appropriate speaker. By that I mean that you must not use your speaker without the cross-over (this is the name of the circuit) since this can harm your speakers. The sound from a speaker without crossover will be terrible for your ears too. Eventhually you can try to connect your tweeterat the amplifier's output leads, assuming that the volume level will be very low. Using this connection you can just check if the tweeter is working ok or not, so you can find where is the problem. By the way I don't think that a coil is burned out, try to see some resistor possible burned out.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

I have just brought a 2nd hand Technics EH 780 but can't get the tweeter to work on the speakers, is it a problem in the set up of the amplifier?

Disconect the speaker(s) from the system. With a 1.5 volt battery touch the negative wire to the - of the battery. And for a short time only, the plus wire to the + of the battery. You should hear a pop! You might need to put your ear to the tweeter to hear it working. if it doesn't make any sound it's not working. Before chasing around for a new tweeter, open the speaker up and apply the test to the tweeter itself. If it now works the crossover part is faulty.
Tweeters are often the first to go when people run the amp at high volumes, so both could have gone!

Only 3 speakers work!

I took the bottom off my go play to have a look inside, the internal port is connected to one rear speaker grill and the other is blanked off, so no sound will come out of that one.

Full sound not working

I had the same problem and also traced it back to two of the four 7-amp fuses were blown. I replaced the fuses, but they immediately blew again. I used higher capacity fuses (10 amp) to see how bad the problem was and those blew. Testing the problem a third time with the speakers disconnected yielded the same results.
There's an internal short in the system.
The solution? Don't buy RCA again.
