Subwoofer pops during play randomly...?

[gggooolllooo]

I just picked up an infinity ssw 210 subwoofer from goodwill the other day. it did not come with any cables or anything so i just picked out a cheap random ground cable from goodwill too. The sub sounds great but when i play it at moderate to high levels the sub booms/pops for a second. its as if it gasps for breath if that makes sense. could the cord i have for it just not be stringing enough power? or is the sub just a little wonky?

Thanks guys!

Not sure what cable you bought. That name makes no sense.
This sub is a powered sub as best I can tell so the cable has minimal power on it.
Also, the sub has limits. Perhaps you are trying to get more out of it than it has to give?

I dont think im pushing it all that hard. Its probably the cable is what im thinking . How does that name not make sense? its says 120V on the cord...

Apparanty, your sub disagrees with you on this.

Its probably the cable is what im thinking .

Your thinking is wrong.

How does that name not make sense?

In more ways then we could explain or you would understand.

It sounds like your mind is made up, so why bothering asking us?

its says 120V on the cord...

That's agood start for when you look for a "better" cable.

If you care, when my Velo 1210 started doing something like this, it turned out to be a small rend between the surround and the passive radiator, but obviously you know better.

Regarding the name, he was referring to you calling it a "ground cable." Those are used to connect a component to ground, and that wouldn't cause the issues that you're having. I'm assuming now that you're referring to a power cord.

Cables can have poor connections at the terminals, which might be more prone to showing symptoms when the sub is moving more (at moderate to high levels). So, it's not out of the realm of possibility that a cable is causing this.

You could swap out both the RCA cable that you are using to connect the receiver to the sub (which is a more likely cable to have issues), as well as the power cord, to see if that clears it up. It might, it might not. The sub may very well have been at Goodwill because of this issue.

My thoughts exactly Adam!

You buy a subwoofer at Goodwill...add a power cable...sub makes a popping sound & then wonder if its the CABLE!!?? Let's take a step back...you bought the sub at Goodwill!!! I'm sorry but there is a reason it was between a Speak&Spell & a SpongeBob pillow!!!

I hope you get it figured out though buddy!! All joking aside!!

I've heard subs pop when the power goes off/on. Silly idea...does that bought seperately power cable vibrate loose at 'moderate to high' level? It can't hurt to check for a loose connection...if you're comfortable with it, pop the amp and speaker and look for a loose connection or terminal.

"Popping" is most likely the voice coil bottoming on the magnet on the return stroke due to over driving it. It sounds like 2 pieces of wood slapping together or a bat or hammer hitting the inside of the sub. If you turn it down, and play the same source, and the noise goes away, then you had it up too loud.
