I have the Paradigm P-30 stands made using heavy steel. They have three tubes I have filled with sandbox sand.

I have two pairs, one used to mount a pair of Mini-Pods. Because of their lighter ABS cabinet it was necessary to use "Blu-Tac" to secure them to the stands and eliminate vibration. The "solid" stands and mounting made a huge difference in sound with the Mini-Pods. The other stands have a pair of T&A P30 3-way speakers mounted. They're heavy enough Blu-Tac wasn't needed. Also sound better with the filled stands. Lead of course would be heavier, but unless your tubes are very small, snad should provide plenty of bulk and coupling to the floor.

The glass plate in the stands I have are termpered and very thick.
I was concerned about the glass plate, but have never had eny
problems with the glass cracking, ect....I'd say maybe the sand
added an additional 8 pounds max.....the tubes are not filled up
to the top, closer to a little over the halfway mark. The stands
are extremely durable and look great (they should be cause they
cost alot $),

Your suggestion about using blue tack is a very good one, it's what
I use and have found it to very effective to holding a speaker in
place....
