SOURCE: JVC RX-618V SOUND IS MUFFLED

check to see if the radio is clear. If it is it may be the signal going into the amplifier. if it is muffled as well, depending if you have an Equalizer hooked to the unit. This also could cause the problem. Finally check the bass, treble balance and volume knob but turn them back and forth while unit is on and see if signal clears up momentarily. if this is the case the control knobs need to be cleaned. Also spin the connection jacks {RCAs} in the rear and see if this clears it up. If not you may have to have the unit serviced by a professional.

If all others had been fine before this problem arose, and you are sure that you haven't changed anything in your amplifier's channel selection menus, the problem might be deeper to solve! Try these out; 1-If the amplifier has a test menu to check out all channels plugged in, activate it. You must be able to get sound, which is like rustle, from each speaker. 2- Check your plugs, cables etc. be sure that there isn't any short circuit 3- Grab your amplifier's remote control and find the "channel selection menu" that allows you to increase and decrease volume levels for each speaker independently.

Did you press the "TEST" button on the remote? It will send some white noise to each speaker that is hooked up, one at a time.

SOURCE: Bass speaker not working

make sure speaker voice coil are still good...continuity checks will confirm this....as far as 6 channel hook up, you need to know what the lowest impedance allowed is from your system and then wire up your speakers in series /parallel to come up with a final impedance that will very closely match the systems minimum output impedance

My jamo d115 speaker tweeter distorts or rattels when any serious bass kicks in, how do you stop this?w


Possible this is a distortion from the Amplifier if the speakers are not damaged. however it is important to switch the speakers to confirm if the fault is relative to the particular channel in which case the amplifier is faulty. If not the speaker can be the culprit. All what is needed is to reduce the BASS level a bit lower when the volume is increased so as to allow the cross over to work. Also if teh cross- over network is faulty within the speaker the bass can vibrate on the tweeter.

One of my MR8's has only its tweeter working, im guessing the bass driver might be blown? How can i test this though and be sure it is the bass driver and not just a simple electrical fault?


Open the unit and remove one wire from one of the woofer terminals and using an ohmmeter check the resistance between the terminals. It probably should be between 6 and 16 ohms... they don't give the specs on the speaker... if it is very high or infinite resistance, the voice coil is blown and you be re-coning or buying new speaker. These are close in speakers and intended for a small room for studio listening while mixing. If the speaker is OK, then the bass amp in the cabinet has a failure... pray, as that is cheaper to repair than a speaker.

No sound from tweeter bx5a


First of all, never connect the audio from your receiver directly to the tweeter. You can blow the tweeter instantly. The mid-bass driver can be damaged from a direct connection as well.

Since you get absolutely no sound from either driver, this seems to implicate the crossover. If the crossover has opened, no signal gets through, if it has opened early in the signal path.

But, it is also possible that a short exists, and that perhaps your amp cuts off the output having sensed a short. The short could be in the crossover or one of the drivers.

Here are some troubleshooting tips--

To prevent damage to your amp, turn it off while making or breaking any connections inside the speaker boxes.

Write down which wires get connected to which place on the drivers, so you can get them back where they belong.

With your amp turned off, connect the bad speaker to your amp. You've already verified that no sound is produced when both drivers are connected.

So, with your amp off, disconnect one wire from the tweeter in the bad box.

Briefly turn your amp on and listen for sound.

If you get sound, the tweeter is shorted.

If you get no sound, with the amp off, reconnect the tweeter in the bad box and disconnect one wire from the mid-bass driver.

Briefly turn the amp on and listen before turning the amp off.

If you get sound now, but not before, the mid-bass driver is shorted.

If you got no sound either way, check the DC resistance of the mid-bass driver (only, not the tweeter. Ohmmeters put out a small DC voltage to test resistance. That DC voltage might damage a tweeter, maybe. Don't risk it). Ohm the mid-bass driver while it is not connected to the crossover. If the driver is good, you should read some ohms--a little less than the stated impedance. An 8 ohm driver might read 6.5 ohms, for instance. If you get an open or a short (with the crossover disconnected from the mid-bass driver) you have a blown driver. Two actually, since neither the tweeter nor the mid-bass driver produced any sound in the previous tests.

If you can't get ahold of an ohmmeter, try this--

Open the good, working speaker and place the two side by side.

Connect your amp to the bad speaker box only.

With your amp turned off, disconnect the wires from the mid-bass driver in the bad box and connect them to the mid-bass driver in the good box. Disconnect one of the wires from the "good" mid-bass driver first, so you don't have two crossovers connected to it at the same time--even if only one of them will get powered on. It keeps the confusion down to a minimum when trying to isolate your problem. Oh, and disconnect one wire from the bad tweeter, in case it is shorted.

Turn the amp on and listen briefly before turning the amp off.

If you got sound, the "bad" crossover is fine, but the "bad" mid-bass driver is blown. And, since you got no sound in the previous tests, the "bad" tweeter is blown, as well.

If you got no sound, try it the other way around. Meaning--

With the amp off, disconnect the speaker wires coming from your amp from the bad speaker box and connect them to the good speaker box.

Your amp is now connected only to the good speaker box.

With the amp still off, connect the mid-bass wires from the good box to the mid-bass driver in the bad box. Remember to disconnect one of the "bad" crossover wires from its own driver first, so only one crossover is connected to the "bad" mid-midbass driver. Remember to disconnect one wire from the "good" and "bad" tweeters, so the only sound you hear--if any--is from the "bad" mid-bass driver, powered by the "good" crossover.

If this produces sound, but the previous attempts failed, you have a crossover problem.

If you still get no sound, something went wrong and you need to retest the good speaker by itself and back up a few steps and try again.

Assuming you got sound from the "good" crossover while it was driving your "bad" mid-bass, make sure no wires have come loose inside the "bad" box. Assuming you have sound connections at each end of each wire, you now need to desolder the electrolytic capacitors from the circuit board.

Make sure you mark them first, so you can put them back where they belong.

You can remove only one at a time, if that helps.

Use an ohmmeter to check some components.

The big red coil should read pretty close to a short, maybe one ohm.

The capacitors should read open or infinite resistance, although you might see a steadily increasing resistance while the capacitor charges up from the ohmmeter. If you read a steady low resistance on a capacitor after it has been removed from the circuit board, that capacitor is bad and must be replaced. The markings on the capacitor should give you some clues as to the proper replacement.

All things considered, I suspect that your problem is a shorted electrolytic capacitor. But, I gave you all I could think of so you can narrow it down and isolate the problem, whatever it might be.

I hope this helps.

How do i install my component


from the speaker outputs of the head unit / amplifier. Connect from the positive and the negative outputs to the respective positive and negative input of your X-over box. Now connect from the X-over woofer/midbass output to the bass driver. Now do the same for the tweeter from the X-over from the tweeter output to the tweeter. Make sure that all the positives and negatives are correctly connected.
If you are going to use your head unit to power the speakers then you should know that:
White & white with black stripe is the Front Left Speaker output
Grey & Grey with black stripe is the Fron Right Speaker output.
Green is rear left
Purple is rear right.
I think you get that the black stripe speaker cables are the negatives.
good luck

Hello there i have a mackie srm 450 speaker system and im not getting any high end tweeter sounds just bass only what coule be the problem manay thanks Paulie


The most common cause of this is a blown horn. A replacement can be ordered from Mackie directly. Remove the screws that hold the plastic horn in place. At the rear of this part will be the tweeter assembly that unscrews from the horn. This needs to be replaced.

Another possibility is that the tweeter driver has broken from the horn itself and is inside the cabinet. Remove the horn and you may find that the aluminum part has broken. Replace the horn which comes with that part and you should be fine.

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 www.wharfedale.co.uk 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 (karl@simpson.nom.fr)

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

My speakers sound flat with no highs at all


I am trying to work out if you have damaged the speakers and amp too.
Have you tried a pair of headphones on the amp? If they sound ok then your amp is fine.
Assuming it is, then speakers have what's called crossover units in side each of them. This splits the sound into three parts. Bass, midrange, treble. The bass is handled by the woofer's, the midrange by a middle sized speaker or or it's combined with a tweeter, which of course handles the treble.
Connecting a 1.5 volt battery across any of the individual speakers will cause it to pop if working. If the speaker then is not getting sound then the crossover unit is to blame.
When you look at the crossover unit, it will have coils and capacitors (non polarised) on it. The bigger ones deal with the bass and the smaller ones treble. If you find a fault say on the crossover of the speaker, for example no treble comes out of it. Then start by replacing the capacitors. Use the same value as on the capacitor and remember they fit any way round.
