@roxy54 --
When I started the thread, I assumed that everyone would name the brand and model of the speakers, not just the height and weight. I think that makes it much more interesting.
Duly noted; Electro-Voice TS9040D LX main speakers (actively configured), and the tapped horn subs are a freely shared design over at the AVSForum (by a guy named "lilmike") called MicroWrecker (the middle sibling of the LilWrecker and PicoWrecker tapped horns). Mains are 6 ft. tall and mains + subs combined weigh in at ~385lbs (175kg) per channel.
My setup is display in Steve's video blog below from 8:07.
