Altec 604 8G questions-

I bought a really nice pair of Altec 604 8G speakers today at a rummage sale for $150. I don't know alot about these, but instantly knew they would better my Klipsch KG4's. These monsters are BIG and Heavy.

Are any of you familiar with these? I hooked them up tonight and they are very efficient and sound very crisp and clean. They are definately keepers for me. What would be an ideal setup location for these? My room is pretty small.

How do these stack up against some of the better modern speakers?

I should also mention, that I am definately on a mid-fi budget, Marantz 2252B, tweaked Thorens TD160, Linn LVX, Denon 110 cart, and live in the SW corner of Missouri, so good audio is almost non existent around here. Which makes the Altecs feel like I hit the lottery.

Comments appreciated!
