The boom is greater with more watts, but it depends on the speakers efficiency BIG time. If you like Boom Ting go with Klipch. If you are having a frat party Klipch Horns. They sound awesome at lower volumes (ie < 120 spl) too. Have listened to them extensively. Would pair extremely well with the 1980.

I have seen it listed as high as $5500, but usually in the $2 to 3K range. I paid $670.

I have the original CS-922A speakers (paid $127.50 each). It takes a lot of power just to light the first green light on them. I had a pair of Bose 901 Series IV (rated unlimited power) but they had to much hiss for me. I paid $610 for that pair, but sold them years ago. I kept a poster on the wall and at volume could make the poster dance with all of the air going out the back of the speaker.
