Subwoofer pop and thump

Danthus · 27 Oct 2015 at 21:57

My subwoofer randomly makes a pop/thump noise and the green light changes from green to red.

I have checked all the obvious stuff and replaced the RCA cable but it still happens.

Subwoofer is a Wharfedale Diamond 60 and the amp a Onkyo 414.

Any ideas?

Yeah, completely random.

Volume, Phase.

Two buttons, Auto On/Off and Phase 180/0

I have just put the opening scene from Saving Private Ryan on, the sub is on but the light is red, no mater what I change on the sub, there is no bass.

99.99% sure it is the sub woofer, I have swapped cables etc.

The amp config hasn't changed so I can't see it being anything else.

In for a penny in for a pound, time to take it to bits.

Well I have taken it to bits I have no noticed that one of the fuse holders is broken.

I can see four capacitors too, just trying to find a multimeter now.

There's quite a few more than four capacitors.

What are you planning to do with the multimeter?

There were four large easily accessible ones.

It seems to be working now, although it still does it, just nowhere near as often.

I am not that bothered as Santa will be fetching me a new Amp and Speakers I feel.
