I've done both with and without, no difference. I have had water in subs in both scenarios. I believe the instructions do not mention adding pea gravel if memory serves correctly.
I tested for air escaping while playing and on the rear of the sub, there is massive amounts of air escaping where it should be sealed.
[Link: dropbox.com]Did that enclosure have any gap when it arrived?
Those ends need a lot more screws- if the cover isn't rabbeted, there's no way I would expect it to remain flat and sealed when temperature extremes are hit.
I would use a sealant like 3M 4200, not silicone.
