Title: LAB sub - loading the drivers and testing / first run precautions ?
Post by: Christoph Meyer on December 19, 2011, 05:22:03 am
Hi,
I couldn;t find anything about it, so here it goes.
We got our LAB Sub cases built, now we're about to load the drivers and test them the next days. Now, with the last steps and the  first run, there's 2 things we've been wondering about.
When mounting the drivers, what's the best way to seal them ? In pure DIY spirit, one could just bolt them onmto the wood and seal the outer edge with silicone, but there's better approaches I would think ? As in, would a rubber ring/layer inbetween the drivers mounting surface and the wood that would compress be better ? Or maybe there's better ways I can't think of ?

And the second maybe even more important part - once assembled and ready to run, is there a way to test if they are airtight without risking to blow them right away if they are ?

Sorry for the newbie questions, but I couldn't find anything about it.
Cheers for your ears from New Zealand.

I loaded some front loaded cabinets a couple months ago and bought some weather stripping tape from Home Depot. I bought a 50ft roll pretty cheap and it worked really well for that application.
