Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection.  Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.

If the crackling is on the subwoofer only, it might be damaged from bottoming out.  See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.

Which subwoofer will sound the loudest?


When you're looking for a loud subwoofer you'll need to consider sensitivity, enclosure type and available power. You'll need to start with a subwoofer with a high efficiency (sensitivity) rating housed in a ported or band pass box.
Power the sub with an amplifier that has a power output that is within your sub's recommended power range. You'll achieve the slam you're listening for. Using an amplifier with a bass boost control can also help.

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

A wire inside the cable has probably come loose, unless you (or a friend) have decent soldering skills to just replace the wire form the audio controller (most likely spot to have problems) to the PC they are probably just trash.

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 have a wharfedale svp15 passive loudspeaker. The subwoofer has started crackling and popping at low volumes and has no deep bass. At high volumes it sounds great as usual and can't tell if the crackling...


Information I find online says it an Active Subwoofer, so that introduces its own amp as a possible source of the symptom. If there is another version of this model that's passive, all the more reason to believe the amp is the problem because passive speakers don't spontaneously emit sounds.

If there was a physical reason for the crackling I would think more power would make it worse or blow it up.

A poor sub signal cable connection might explain low current anomalies if random noises are entering the signal path.

Make sure the signal, speaker and power cables are not aligned parallel and close to each other.

I just took my sub apart and found that the surround on the driver speaker inside the sub was totally crumbled and lying in pieces throughout the sub box.

Subwoofer/Bass not working


I apologize if this question sounds offensive, but did you plug the power adapter in to an electrical outlet? When the power switch is on, do you get any LEDs or an audible thump or hiss from the subwoofer?

Cerwin Vega V-10S Subwoofer doesn´t sounds good


dear "rai17"

This, to me, is most likely the voice coil inside the driver rubbung against the yolk plate, or possibly the spyder slapping the metal plate underneath it, or the amp-(if it has one?) getting tired. this can occur from poor build quality, or playing the subwoofer too loud. depending on how much it cost you, you may want to get it repaired(voice coil re-alignment or something or new amp). But the way it seems, it is probably the driver itself. subwoofers get looser as they break in. This one may have been over-broken....sorry

I hope this helped clarify what is happening!
