Try to blow it out with compressed air. Then, with the speakers turned off, turn the volume knob to full volume and back as quickly as you can (without damaging the switch) three or four times. This should take about one second for three movements. Undertake this at your own risk. Turn them on and see if it has helped. Do not just keep doing this. if it doesn't help immediately stop. if it does help, repeat blowing out and repeat the knob turning, once.

Subwoofer makes noise like an untuned TV regardless of volume knob

I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

Be sure that your plugs are in the correct port and fully seated. Try readjusting the system volume and adjustment on the speakers, if either is at extreme, overamplification happens....

It could be a safety protection meaning you could have a shorted speaker check all speakers and wiring, or it could be a defective volume control, try cleaning the volume with a contact cleaner spray you can find at any good electronic store (you normally have to open the radio to reach the POTENTIOMETER/VOLUME) to be able to spray inside it, than alternate (high/low) the control repetively to move/clean the volume's circuitry

Good luck!

My speakers sound is terrible now. I changed the

Forst thing is to put a known signal into the speakers, say from a CD recorder to isolate a possible mixer or other source being marginal.

If the sound is still bad, verify that your volume settings are reasonable.

DO NOT crank the gain on these speakers full and then throttle the signal to them as that cause poor signal-to-noise ratio.

If you have driven these speakers very hard (these are only INTENDED for lower level monitoring within the engineer's booth), you MAY have damaged the speakers. It htat case, repair will be necessary.

Try to determine if the lows or highs or both are bad sounding.

Noisy channel of receiver

Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?

Logitech Z2300 rustling sound on volume knob movement

I would definately not open up the wired remote. As for the rustling sound, I had the same problem with my set (only with a hissing sound instead of rustling). Make sure the output on your computer is all the way up, as well as the volume on whatever media player you are using. That eliminated the sound for me, but it might be a different problem alltogether.

Speaker noise

The contacts on the volume control (potentiometer) get oxidized over time on any analog rotary volume control. With the power off, crank the volume control back and forth real fast for a minute or two, this will do the most cleaning of the contacts that you can do without access to the insides. Ultimately you'll probably need to sprary some tuner wash/tuner cleaner or other electronic parts cleaner in the know (with the electricity disconnected) and then work the knob back and forth. Tuner wash bottles are available at electronic specialty stores or radio shack and usually have a long extension tube (like what comes with WD40). You might be surprised where you can reach with the extension tube.
