Sound quality change


One of my speaker wires came loose and made contact with the other while running. It popped and went dead. I turned the HK amp off repaired the wire, turned on the amp and crossed my fingers.I've got pretty good sound but it seems to lack the incredible headroom and midrange it had before. Is this a problem with the speakers or my amp and what can I do about it?

Let me see if I am understanding this.Somehow one chanel of your HK amp was shorted ,But only for an instant.When the wires touched we are hoping that the protection circuitry shut down the HK amplifier . Here are some things you can check:

  1. First and most likely thing: is there any chance that you reversed the speaker leads and now the speaker is playing out of phase from the rest of the system.
  2. You can check and see if it is the speaker or the amp by putting one of the other speakers in the system in that same spot, but make sure that speaker is in phase as well.
  3. Run the channel you think you may have damaged through one of the good speakers that you know is not damaged.
If you set two speakers together, while they are playing they should be beating in and out at the same time. If a speaker is out of phase while one goes in the one that is out of phase will go out and vice versa.

If you still have not narrowed down the problem, there might be a problem with the amplifier itself. For future reference, if I have an amp and speakers that I like, I will put a small fuse right at the point where the wire comes out of the amp: put it on the +(hot) wire. If you have any more questions feel free to ask or myself.

If this helps you with your problem, please let us know.

My jbl flip speaker was making static like popping sounds,then stopped,i let it run dead so i could fully charge it and now it will not hold a charge over 30 seconds,is the battery burnt or something?

Unfortunately, it sounds as though the wrong wires were touching when ot was popping. Then it probably got hot and melted the sub standard soldering jobs in these things. I had a Roker do the same thing, opened it up and fried, wires not insulated and against each other. Sorry poor quality, speaker even though expensive. Can you return it? Contact the company.

Will Bi-wiring these speakers give a noticable difference in audio sound quality ?...I'm using them with a Harman Kardon HK 3490 receiver..

Hi gregorygoff
This speaker is already having its own crossover PCB inside the box, the xover frequencies are all set as per the speaker's response. So, there will be no point making it Bi-wired.

Can I turn the Logitech z-2300 to a 4.1 speaker system?

You will need a separate pair of powered speakers to do that, plugged separately. The quality of the sound will remain the same on the front ones, the overall quality will depend on the new ones.

Humming sound (speakers)when HK AVR is powered up.

In my case the buzz was only on front speakers. There are 3 capasitors (100uF/25V) very close to the cooling ribs of 3 regulators in the power supply. In my case the C922 was bad.

Crackling and popping sounds in surround sound speakers

Could be your head unit or the connection to the speaker may be bad. Also if the wire to the speakers in your ceiling is bare and touching any ground it would interfere. Start by checking connections by playing something and messing with wires. Listen for a difference. Next check by putting the wires that power those speakers in a known working output and listen for different quality

Ihave a JVC G230 and there is no sound

you have one speaker that has a short, a good way to find it quick is turn radio off and on if any of them pop even the slightest that is where your problem is...if you dont hear a pop check that all wires are not touching a ground somewhere this send the unit into protection, just one speaker or wire will do this .it keeps the radio from burning up...

No speaker sound with hk 3480.

your fuses are blown by possible crossing speaker wire - and + together. I did this and kept turning it on but I ended up frying the unit. Check your wires and make sure that they are seperated properly. If problem continues then unscrew the shell and replace 1 or all 3 fuses (depending on what was blown) with GMA 8 amp fuses. good luck.

No sound

Check device manager and see if it shows up there. if you have a yellow question mark or red x, install or re-install driver by right clicking on your sound card and uninstall and scan for hardware changes.
Please let me know how you make out.
