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

I guess that I will always like making heavy stuff. The speakers that I have now are 80 lbs. each and 40" tall. Pretty narrow at 11" wide, and 15" deep. So, for their size, they are chunky. Making a set of even heavier speakers out in the shop. Basically, it is the layers of MDF, solid walnut, and Corian that add up.

Altec A7s.
