JBL Northridge E250P making popping sounds..... (1 Viewer)

[Coryp81]

Hello. This problem has been happening for awhile. When i play games or watch movies, after a while my subwoofer starts to make popping sounds and other little noises. When it does the popping, the light blinks between Red and Green. I have it hooked up to my receiver via a RCA cable I had laying around. Is it because I am using those cables? I am looking for a direction to start going into to resolve this . Thank you.

Usually that is a sign you are asking for more bass than it can actually produce...
But, if it is EMI causing the problem...replace with a shielded cable.
Shielded subwoofer is the same as digital coax and composite video(the old yellow cable from the days of VCR). So, do you have a really long yellow cable laying around not being used?
If not...

How do you tell if it is a shielded cable?

 

[schan1269]

Easy...
RG6 is obvious.
RG6(comcast/Time Warner/Dish Network/Directv)=composite video=digital coax=shielded subwoofer.
So, find a composite video cable laying around the house and compare it to the RCA you are using now.

If you have a spare piece of coax(RG6) laying around from when your cable/sat was installed...buy a couple of these...

I am trying a pair of component cables I had. they are shielded. I am hoping that is the problem.

 

[schan1269]

Oh yeah, forgot component...but yeah, component is the same thing, just in triplicate...

 

[Coryp81]

Well, so far so good. But I am not happy until a few days goes by without incident. But thank you. The whole shielded versus unshielded thing never occurred to me.

 

[Coryp81]

ugh..it started doing it after a couple of hours where it worked fine. None of the settings on it are at max. Could it still be over worked even if that's the case?

 

[schan1269]

Or the amp is just dying. How long have you had it?

 

[Coryp81]

hmm..i want to say around 7 years.

Perfect excuse to pick up one of these...

or (and yes the Kevlar driver is worth the expense)

[Coryp81]

is that about the equivalent to the one I have?

 

[schan1269]

The F12 is probably equal. The VK12 would up the ante.

 

[Coryp81]

hmmm..if only i was rich...lol

Then you could get a "Thor's Hammer" by Wilson Audio. MSRP is $20,000+ and you have to buy an amp for it. http://www.wilsonaudio.com/product_thor.shtml

 

[Coryp81]

well..if you think the F12 will be about the same. i just don't want to lose anything with the new sub.
