help with speakers that rock, pleeze

Ever thought of just getting a pair of matched subs? Set them right at the base of the Sparks and roll them in at about 50-60hz, and you should get some of the low end that will open up the stage on those speakers. I've got Sparks and love them without a sub, but I'm in a much smaller room, 15 X 12. I've tried Maggies, even the larger AP Tempos, and the Sparks are better to my ears. I think it has to do with the dispersion of the 3/4 tweeter.

Another vote for the Legacy Focus 20/20.

Change your speakers. They are "Norah Jones" style speakers and they are not capable to rock in such a large space.

Budget?

Ive owned the Focus 20/20's, best speakers Ive ever had. If you can afford them, buy them. They are loud, and rock. They also sound better with jazz then anything Ive heard. After you realize what big speakers with large bass drivers sound like, you realize how much we over pay for small, wimpy speakers. And I speak for the many floor standing flagship speakers as well.

I imagine the CLS-215's are worth a listen. If the tweeter isnt harsh or brittle, it may be a great bargain if you dont have the funds for $2500 used 20/20's.

If money isn't an obstacle, take a peek at Eggleston Andrea IIIws, or just the IIs. At that point or just before it, the Whispers from Legacy should definitely fill the bill... but amp change is going to be a must then.
