I can't remember the exact weight, but its only just a one man lift. they was built for a chum with large electrostatics (er audio kits) and his surname was Topps, hence the name. He did the woodwork and metalwork on that one, and I did the design and build.

They sound good on the statics, a bit of an overkill for normal speakers that would be used with SETs (they produce about 40W) . Marco heard them on Colins statics at Owsten I think.
