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

Legacy Whisper (original version) 63 inches tall and about 215 pounds if memory serves.

Love this question! Fun.
Vandersteen Model 5: 185lbs each

Acoustat 2+2: 94" H by 20" H by 3.5" D

Some years ago I bought Sony's largest, most expensive, range topping subwoofer, about the size of a wardrobe. Part of their 'esoteric' range at the time. It was absolutely terrible. The only time it sounded fine when when it was switched off.

maggies the tallest. university theatrical blasters the heaviest, tied with the maggies for height but they were about 3' wide pentagonal in shape and each one was prolly over a hundred pounds. with just a watt or so those speakers would energize the air in the room and make you feel like you were at a concert. relatively colored though, not even comparing them to the maggies.

Klipsch CF 4.   Heavy and tall.....
