Ideas on securing some sierras on the BT77 mounts?

I have had a 340 on one for about two years now. Have moved a bit!

So they have moved a little? outward or what?

well i was laying in bed this morning asleep enjoying a nice dream when all the sudden something sounded damn near like a gunshot. Sure enough i jenksed myself, i jump up and one of my speakers isnt supported on the wall by the mounts. Was up there for about1.5 years i believe, Just the other day i was saying i think its tight enough just clamping it together when now i know thats not the case.

I think the speaker is ok no visible damage to the speaker midwoofer or tweeter. The front grill absorbed most of the fall ill plug them in later and make sure that the internals are good if not i guess its time for an upgrade to sierra's lol. Time to buy some speaker stands.
