flex-seal is your friend.

I actually grabbed a can today.  But I also grabbed some roofing sealent since it is waterproof, and a rubberized material that is flexible as well.  I already added the roofing sealant and will then go over that with the flex seal spray.  I sprayed the area the wire comes out of the rear.

I do want to talk to Snap about this though as none of this should be necessary.

I think with the Flex seal spray you might have to use the whole can at first use because the spray head clogs after first use. I've stayed away because of that, anyone know if that's true? I've always thought the stuff could come in handy for outdoor sealing otherwise.

any subwoofer enclosure has to be air tight at the seams for proper functionality.  how can they skip this step on one that goes in the ground?  i'd expect this out of the boxes that kids would bring in at the car stereo shop I used to work at.

My thoughts exactly John.  I don't get it either.  The amount of labor to install a 12" burial sub is extensive for some of us old folks.  To dig it up can be even worse.  Not to mention the disruption to landscaping that is completed after install.  It simply should not happen

My guess is that the failure point is the rubber elbow. Once water gets inside it rots the wood and causes it to pop loose at the seams.

This is what the Sonance subs installation manual says....

"When placing the rubber elbow onto the subwoofer, it is recommended to add General Purpose Marine Grease to the inside of the elbow. This grease is available under the brand name Sta-Lube. This lube will act like a water barrier and ensure that water won’t enter in through the elbow connection."

The Episode manual doesn't mention this step.

On every one I install i first clear silicone all the way around the tube that is part of the tub. This helps the rubber snorkel slide on and also gets silicone on the inside.
Once thats on and tight I then silicone around the outside between the snorkel and what is left showing on the tube part which is not much but I put enough silicone on that no water is going to get inside. I do this for both the tube side of snorkel plus the mushroom side of snorkel. Also I do the wire connector on back of tub.
Doing it this way about 2 years now.

Maybe plastidip or hot tar (or both) the whole thing before it goes in the ground :)

Could be totally wrong, but I was told the episode sub has problems because the back of the sub is facing the opening. The sonance the front of the sub is facing out.

Great Scott! You are right. Maybe a flux capacitor installed on the leads could offset the negative phase array, creating excess pressure from one side of the sub to the other.
Whatever you do, do not install a plexiglass window with RGB lighting. You would need 2 flux capacitors to make it work like those car audio 4th order band-pass boxes you see.

Hmmm.... Wait a minute...

Told, by whom and how did they explain why this would make a difference? If the cone is trying to move toward the end of the enclosure, is there more force when the cone moves out vs in?

if the back of the sub is exposed to the port side of the enclosure, it could be getting damp, which would be bad for the back side of most speakers.  if the front side faces the port, chances are the cone and surround are made out of plastic and rubber which would be fine.  i'm guessing that's what was meant about how the sub orientation could be affecting the life of the product.

Good point- and a plastic cone/surround could be an indicator for where the water is entering, by preventing it getting to the other side (assuming the rim is well-sealed).

All of the dead subs had water on both sides of the subs
