Strange clicking sound with high volume low frequency audio

[hugooknapp]

Hi Guys,

I'm having this strange annoying clicking sound appear when a low frequency sound is played at high volume though my subwoofers. I have also had this appear on another subwoofer I have used in the past but only now has this strange quirk started to get annoying as with my last speakers I never turned up the volume to this level. At first I thought it was a problem with the lepai lp-2020a+ amp so I bought a slightly different amplifier (eBay link bellow). This exact sound still seemed to occur with the same speaker at the high volumes so I'm baffled as to what it is?! So I'm just wondering if anyone has any ideas as to what it is?! *scratch_one-s_head*

I've linked bellow a video of this sound occuring with the speakers!

What PSU are you using? Are you running it from a car battery?

the cone reaching its physical travel limit, or as I have discovered, a cr@ppy test tone from YTube. I eventually found better ones with no clicking.

Best not to comment if you don't have a clue, really.

or you need to spray water on cone,if it is made of paper,and leave it dry.I did it on one cerwin vega's bass driver.And clicking sound disappeared

It's obviously nothing to do with that either.

No i'm running it from this adapter (http://www.amazon.co.uk/gp/product/B00C676JNM?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00)

I have tried other adapters such as the one provided with the amplifier.

It claims a peak power of 300W. A 5A power supply won't be good enough for the power output, you need a 25 amp one at least. If you can, hook it up to a car battery to test it. I'm fairly confident it will work OK then.

That was the first thing that came to my mind.

The speaker driver looks to have a very small diameter to be a subwoofer. The sound level that any driver outputs will be related to the frontal cross sectional area, and the physical travel of the cone. To generate a loud volume at 30 Hz, the driver needs a large frontal cross sectional area, plus the ability for the cone to physically travel a large enough distance. I think that driver fails on both counts, for use as a subwoofer, consequently when the volume is turned up high, the driver reaches it's physical limits.

I have tried many differnt types of PSU's from 1.5A to an 800w PSU from a computer. It makes no differnece sadly. *unknw*

Yes this was one of the theories I was contemplating that could be the source of the quirk. I'm thinking of ordering a new subwoofer driver to solve this but i'm worried that it might be the amp not the speaker.
