For the past week I've been setting up a theatre space by rolling three full-sized speakers into position. It's a pleasure to push 3 Altec 4A, dual 15 cabinets (w Altec 515s), with wings, into a line. On top there are JBL 2446H drivers attached to JBL 2360B horns. They are on wheels, but at almost 10 feet tall and about 800 lbs. each, it's a push for sure.
Then I roll in a pair of JBL 4642A dual subs into position.
When they power up you're really covered in a BIG sound.
I used to think my 4343s were big, but these Altec monsters make my 4343s look like bookshelf speakers.
