Transmission line speakers is what they were called. Thee was a ton of Cotton wool insulation in one of the boxes and I believe part of the outer box was to be filled with a quantity of sand.
There was a posting for the drivers of these speakers a while back but alas they are sold.
They were in fact IMF so thanks for the lead and I'll carry on looking for a project.
