Wharfedale sub turning on/off all the time.

[atomic punk]

Hi all, long time/first time.

I have a 2 year old Wharfedale moviestar speaker system and am very happy with the performance vs. cost. I am not an audiophile, but I can appreciate a decent sounding system.

The subwoofer is 100w amplified with an auto-on feature. BUT, the last couple months, it has been turning on and off alot during a program I'm watching, regardless of the volume level or frequency of the output of the audio. Normally I wouldn't care, but there is a loud "thump" whenever it turns on and it gets really annoying.

It has two controls: crossover and level. I've tweaked each of them to both extremes and it doesn't help. I've increased the receiver's sub output to max (10) and decreased the sub level to match the other speakers' output, and that didn't help. The only thing I can do is switch the "auto on" off, and therefore turn on the amp manually (but then I have to remember to turn it off when I'm done watching TV)

I have just read tonight about using a Y-adapter and will try that next, but I'm skeptical that this would solve my problem. (hopefully it will though?!)

Any other ideas?

Thanks in advance.

If cranking the receiver up to +10 on the sub's level didn't fix it, the Y adapter may not do the trick, but it is worth a shot. Sounds like something is defective, and it may or may not be the sub... Your receiver's sub out could have an issue too. Does the receiver have preamp outs for other channels? A quick check would be to use the sub from one of the main channel outs, set them to large and see if the problem persists.

The Y-adapter will not help, I had a Warfedale Power Cube 12 Sub apx 3yrs old did the same thing. Turn on & off all the time while my system was off & I was using a Y-adapter. They are good subs but when that happen its time for a new one. I think it's a problem with the amp inside the sub.
