Things that heavy should be put on casters, because of the weight it doesn't compromise the transmission to the floor.
Floor! what floor? I was going to suspend them on a magnetic field,it would only need 32,510 x 0.25inc dia magnets each. To stand just 5mm of the floor, but I had second thoughts, I live to close to London City Airport, and could not get Jumbo Jets in the garden, unless Mrs W. let me take washing line down.

Women fickle crits she said get a hobby but she will not allow me to take up close observation plane spotting. :grin:

Ah, A380 MSN001.
It’s a shame they will stop building them soon.

Thanks for that, I’ve seen a few of the planter videos but not that one. I’m waiting for a couple of stonemasons/granite worktop guys to get back to me. If not I will plough ahead with the concrete casts and look into granite in the future. I certainly want to build some granite speakers soon but they may be more cube1 sized or maybe cubette sized.

I only did one, based on a Wharfedale Kit 5 in 1970, it was chipboard box with lots of nails part hammered in inside to give key and quick setting concrete poured in to line each panel. Worked for bass solidity but as said you needed a forklift to move them, sold them to a friend. Commercially didn't Townsend do one that involved metal, concrete and carpets

Myself and a good friend also did this in the early seventies except we robbed the drive units from his mother's speakers. She had a Dynatron system and the speakers had Dalesford units iirc. We cast the cabs by making a box within a box and used stiff wire as reinforcing. There were bloody heavy and sounded great to a pair of bass freak teenagers. Wasn't there someone called Faraday or a company or something that made concrete speakers?

Anyway I wish the OP well with his project.
