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

Salk Sound G25 Subwoofers. Two of them, weighing 192 lbs each and beautifully finished in mahogany to match Salon 2’s. Best built and sounding subs I have ever heard. They are so heavy, I’m not sure how Jim and his team managed to handle them during the difficult process of installing the mahogany veneer, without damaging them…

Heaviest = Velodyne DD18+ (current HT Sub) ~150lbs

Tallest = Magnepan MGIIIa ~ 6' tall

That's pretty impressive brystonkiwi.

My SDA-SRS2 on both counts 50”h and 135 lb (edging out my NHT 3.3 @ 123 lb)

Legacy Aeris, I believe ~185lbs at ~60”. Not so heavy due to the top having a bit of open baffle. 

Replaced with Wilson Yvette, which was 175 lbs at 41” or so. 

Replaced with Borresen Z3 Cryo, which is about half the weight (85-90lbs) and same height.

Bigger is rarely better.
