What's the heaviest speaker you've ever owned? What's the tallest?

Oh yeah @cey, I've been in a coupla bands with a bassist who owned the Ampeg SVT. Both the head and the speaker cabinet were back-breakers. When I was 20-21 I was playing with an organist whose Hammond B3 and Leslie cabinet were the same. But the worst was hauling around an old upright piano from gig to gig.

Tallest and heaviest are stacked QUAD’s (7’ 10" tall frames that I built myself with three sheets of 3/4" MDF glued together), followed by the 6’ tall Magneplanar Tympani T-IVa, which are the widest (each 51", or 4’ 3". They require a wide room ;-). The ESS Transtatics stand only 42" tall (by 20" wide and 15" deep), yet weigh 140 lbs each (they are built into substantial transmission-line enclosures).
