Speakon Terminal Seal

Hi guys,

I'm in the process of finishing up building a subwoofer (Ricci's Skram), which I'm using speakon connections for.

However, just for fun I made a seal against the back of the speakon connector, and I found out I can blow air through it - not the terminal cup, but the speakon connector itself.

It's not a ton of air, but it isn't sealed between the sides.

Is it ok to just blast it the whole terminal/connector backside full of silicone/caulk/hot glue once it's all wired?

Thanks!

Which connector do you have? I have found that some do allow air through and some don't.

These allow airflow

These do not.

I use the square ones and haven’t had any air blow through mine. I also get the seal for them as well. Maybe that stops it.

I didn't realize it until more recently but I could actually see through the square connectors that I used. The leakage wasn't from around the edges but through the center of the connector. I can try to get a picture of it this evening.

That's what mine are doing too. I'm sure I can seal up the edges of mine against the terminal cup. Not super worried about that. But my scientific testing method was sticking the rear half of it in my mouth and blowing. Air goes through the middle parts where the connections are.

I'm hoping that it's perfectly acceptable to just coat the whole spade connector area on the back in some sort of sealant without causing some problem I'm not thinking of (melting, harder to fix in the future, etc)

Maybe hot-melt glue around the spades? Easy to take off if you need to and would seal it up.

I've been using the round ones. My scientific testing was the same as yours

Regarding the connectors, I do have the square ones since I'm using this plate so I can push this thing up against walls if I need to.

As for the hot glue method - That's probably what I'm going to go with. There's the added benefit of keeping things from jiggling around too much as well. Just wanted to check that there wasn't a better option out there!

Thanks!

Hot glue or silicone. Both work great and ate easy to take off if need be.
Ive had one be leaky out of about 50 or so.

Blasting brown notes for 10 years and counting!
