Best floorstanding speakers under $2000

I read some of the reviews, it does seem your speakers are well made for rock. I think that Zmanastronomy is right, but it sounds like you have the itch for a change, not simple improving what you already have - true? If not, room treatment is a lot of bang for your buck in improving the performance from you system -- especially in the bass. Is that a way you might want to go? Or do you really want another speaker?

OP, when you say "best" do you mean in absolute terms? or just in my opinion? I always thought Klipsch was a brand that tended to appeal to those who primarily listen to rock (i.e., loud with minimal compression).

The very best floor-standing speaker, without a doubt, by any standard, is a used Merlin VSM - which is not often thought of as a rock speaker, but I think does rock quite well, even though it only goes down to 30hz or so - how much rock music actually has deep bass in the recording? Unless you are listening to electronic, I'm not the deepest bass is an essential part of typical rock recordings. Aerial speakers are also the best.

Linaeum66, precisely - bass traps made a HUGE difference for the better, along
with side panels to the sides and front of the speakers to absorb side
reflections - this was at least, if not more of a change, than any equipment
change I have made.

A fellow AGON'er recommended and I used stuff from www.acoustimac.com,
much cheaper than audiophile specific stuff that comes with a fancy theory to
explain the price difference. This company generally sells to recording studios
etc. (professionals) where pricing and sanity are required.

No matter what speakers you have, two bass traps in the rear, and two panels
on the sides should make for a better sounding room - you can do more than
that, but that is a good basic start.
