Hello Everyone,
  I have had my SubMersive HP for a several years now and have been really happy with it. Nothing has changed in my home theater setup since adding the Sub.
 
  Recently, on some of the more demanding parts of intense movies, the SubMersive sounds as if it is clipping or the speakers are bottoming out.  I have noticed there is quite a bit of cone movement and I do not remember if it has always been so.

  Has anyone experienced this?  Any help on what I can do to resolve it would be greatly appreciated.

Thank you,
Gordon

It's never happened to me. Have you noticed if the limit/clip lights come on when you hear the sub bottoming out? If not, look behind the sub at the amp and look to see if the limit light comes on one of those demanding parts.

If the light does not come on and you still hear it bottoming out, try gently pressing the woofer in evenly to see if you can hear/feel if the cone is moving freely. If you hear friction of feel any grit, a driver might be damaged.

Wow, were the holidays busy. sorry for not coming back before now.  

  I pulled the sub away from the wall today and started my troubleshooting.  I put on a demanding LFE track and slowly turned it up until I heard the bottoming out sound.  

  The good news?  The amp is not clipping.
  The bad news? The rubber around one of the woofers is ripped right where the cone meets.

Upon further inspection both woofers show signs of cracking; both where the cone and rubber meets and where the rubber meets the frame. The one has about a 3 inch rip right along the joining.

  Wow, so what now? I am not sure.  ;-/

The sub gets about two to three movies per weekend, hardly under a huge load.  Purchased in Aug 2011.

 I guess I will try to reach Seaton Sound directly.  Any other suggestions?

Thanks,
Gordon

Hi Gordon,

You should already have a response to the e-mail you sent this weekend.

It sounds like a problem might have developed with 1 driver which then left the other flapping without both drivers loading the box.  A rather rare occurrence, but certainly possible.  We'll handle replacement of the woofers by e-mail and have you back up and running quickly.
