Do I need to seal around sub's rim?

post #1 of 5
Thread Starter 
Hey,

I have almost completed the first of a few TC LMS 18" sub boxs and I am ready to bolt the woofer to the box. Do I need to run a silicon bead around the the rim of the sum or will the rubber be sufficient for a seal. Also should I run a bead of silicon around the inside of the box? I used rabbit and dado for joinery.

Cheers

Yes, I would run a bead around the joints inside the box. No I would not run a bead around the rim of the driver. You may want or need to remove the driver. The rubber seal should work fine on the driver.

Definitely don't use silicon on your drivers to get a better seal, as Mike has already said you may need to remove them and you would have a horrible time.

I would actually remove the rubber gasket and use this instead: http://www.parts-express.com/pe/showdetl.cfm?partnumber=260-542

Rubber gaskets can leak so I always remove them and use the gasket tape for a airtight seal. I got this tip from Bossobass a long time ago who is one of the most knowledgeable sub builders on this forum.

Thanks for the comments guys.
I really did not think that I would need to put a bead of silicon around the inside of the box, especially with the joints I used and the amount of glue and clamping. I would have thought the wood glue would have provided a good seal. What would the effect be of a very small leak?

You really do not need to use silicon. What most people do is run a bead of glue and then smooth it out with your finger.
