LF speaker in EVP X makes strange noise

D-644 LF speaker in my EVP X makes strange noise when volume is up
and music has full bass or drum peaks.
After opening the cabinet and disconnecting the speaker I saw that lower part of the cone is disconnected from metal base.
Any suggestions on how to fix it, glue it..????
thanks a lot

    It is a Wharfedale EVP X-15 speaker, not a receiver, in question. And yes I still need a solution for this problem.

This is an indication of some bad solder connections on one of the boards. It could be the power supply board, amp board, or the digital board. I would like to be more specific, but this is not a common problem with those symptoms. Bad solder connection are a common problem and can cause many different unusual symptoms. Unless you have excellent soldering skills, it would be best to let a service center repair this for you. This is a very good receiver and is well worth getting fixed. If you have excellent soldering skills and are willing to take a chance on fixing it yourself you could save yourself some money, but be aware that if you make even one mistake while soldering, you could easily cause much more damage than you started with. Some of the components that may need to be resoldered are surface mounted IC's that are very difficult to resolder and if you have never done this before it is not a good idea to start learning how to solder on such a nice receiver.

Let me know if you need any further help.

SOURCE: Receiver frying noise

I have the same unit and discovered there's 2 cooling fans inside.
one is not working at all and the other is turning very slow.
With that said I'd open the cover and see if it's the fans.

Sounds like your powersupply is going bad. Try going to Sony Esupport.com flat rate calculator.

I have just run a bass test and I am getting bad vibration noises from one of evp subs the sub works but seams to crash at certain frequancies


Over-driving or resonances can be unpleasant and intermittent. Decide which you have. Find some music that causes the symptom.

If you haved two identical subs the diagnosis should be easy enough. Swap them physically.

Lower the volume. Problem solved?

Move the sub around the room to see if it changes for the better or worse. Room boundaries and YOUR position relative to the speakers play a huge part in bass response.

Maybe the speaker cone is damaged or the voice coil is separating.

When my KEF home theatre subwoofer is maxing out on bass, it often makes a loud popping noise. Should I be making some adjustments to reverb, volume, or something else?


Hi,
Yes you should make adjustments.KEF makes very good products, however if you don't handle this you will have to replace or service it.
1 If the woofer is very close to you, relocate it further away. The reason being is that the lower the frequency the larger the wave form. The lowest waveforms will become louder.
2 Adjust the high frequency cut off to be at 80Hz. This should eliminate boom. Higher Sub frequency tend to muddy the sound.
3 The sub should have a subtle effect in music. So the relationship between it and the speakers it augments the sound of should be seamless.
4 If you are playing Rap or Reggie music and you like to play it loud. Add another sub into the system and locate it NEXT TO the KEF Sub. In this fashion the two subs will reinforce each other's energy. They will "couple" thus multiplying their energy considerably.
Hope this helps,
Best Regards,
Mark

I had a set of computer speakers (Altec Lansing BX3). My wife plugged a heater into the surge protector and later yanked the heater plug out before turning it off. Computer went into some freaky cousin of...


Maybe the capacitor in the power supply burned upon unplugging the heater. The power supply is a coil with iron core, next to it, there should be a rectifier and a capacitor. If the capacitor is burnt, the powersupply will still be working, but there will be noise on the line, the 50 Hz that comes out of your wall outlet. Capacitor of the same value can be bought for small change but has to be soldered in.

Can I use front preouts for subwoofer?


First, you have to have a self-powered subwoofer (or two) with this reciver. That means the sub has its own amplifier. These are usually capable of accepting either Line Level (RCA) input or direct L and R amplifier channel speaker wires from your receiver from which it will react only to frequencies in its range. It doesn't actually use any if the power from your receiver's amp.

That is why you can extend your front speakers from the sub. Again, understand this - it is not playing any part in amplifying them. The amps in your receiver are just passing through it.

Setting your speaker 'Type' definition to Large will tell your receiver that they are capable of real bass (as opposed to small satellites) but won't necessarily steal anything from the subs. Set your LFE/Bass Out setting to Both if your front speakers are capable of handling real bass. Why would you want to deny them bass if they can handle it?

This part is confusing "If I can get the sub working on taking the lows out of the front speakers if I set them to large on the receiver then that is one thing less to send to the other sub on the LFE channel". The crossover feature allows you to define what bass goes to the sub. You would use the various points to smooth out the transition between your sub and the rest. Your quote of 47hz spec for something doesn't suggest your other speakers are great bass reproducers. One needs to see the +- db spec with less than x% distortion for that number make any sense.

Your receiver has two RCA Subwoofer Outputs but I'm sure they get the exact same level. If you're having trouble matching two different subs doesn't at least one of them have an adjustment for volume? Or maybe you could use physical positioning to adjust their comparative volume.

More than likely you have blown outputs, as the sound you hear when you touch the leads to the terminals is the DC offset of the power supply being routed through your speakers...accordianman

Denon receiver shutdown


Try turning down your tone controls. Like your bass, treble, or your equalizer. If you hear too much tinny or hissing sounds, the treble has to be turned down, or turn down the upper bands controls on your equalizer to the optimun level. If you hear too much bassy sounds, your bass control has to be turned down, or the lower band controls has to be turned down to the optimun level. If you are planning on turning the volume up, you may have to turn down some of the tone controls to the optimun levels, otherwise, your receiver may shutdown, or you may blow fuses in your speakers. Also make sure you speaker wire polarity is hooked up right. Red wire on the + red terminals, and the black wire on the - black terminals. Also don't have the volume turned up too high to the point where your receiver would have clipping or distortion, or else your receiver may shutdown, or you may blow fuses in your speakers.

If this don't help, then there may be something wrong with your receiver or your speaker.
