Killer Floor Standing Speakers under $4000 for Rock?

tommy - Ohm offers a 120 in-home trial. While you will lose the round-trip shipping, it’s still a good way to audition speakers. My taste in rock music differs a lot from yours, but I can crank my Ohms up really loudly, and they do not lose their grip on the music, or allow the upper-mid/lower-treble range to blare and dominate the sound. That’s one reason I kept them after my own in-home trial. I have heard many speakers over the years (I am active in my local audio club), but nothing that I would dump my Ohms for that were not much more expensive. The closest I have heard would be the Golden Ears. While they are sold only through dealers, you might be able to arrange an in-home trial with a dealer.

Your amp is a little under powered (not even rated at 4ohm) and using extreme high efficiency speakers usually risks compression and lack of balance  (sound dull) at higher levels. 

You might want to rethink your strategy for clean loud rock. 

I had the 14s2 which has 10 less watts but pretty much the same and It was at its best when played high, very distortion free at all levels but if you find a speaker with less efficient drivers and it doesn't give you that bass slam, use it as a pre amp and tie a 300 watt monster to it and that should make most speakers come alive.As for speakers the ones Chayro recommended look like they are ready for business.

Second the mentions of Klipsch and JBL. I have L100's and I can best describe them as "danceable." Prices seem to have taken a dip in recent months. Given that so many old rock tunes from the 70s were mastered on them, they make it sound so true.

i find my Druids to be more detailed, and the JBL's to be more fun. Iove my Zu's and their offerings so really well with all kinds of amps and components. The little brother to the Druid, the Soul series with identical drivers, was a setup I heard at a show. It was running off a Peachtree Nova and MacBook, it left more of a joyous impression on me than the 60k two part Van Der Steens across the hall that were hooked up to all kinds of Audio Research components.

Of course "rocking" and "lively" are just other words for nonlinear coloration and distortion, but my brain told me what it liked.

also, Klipsch and Zu's aren't afraid of corners if the room is treated properly.

Golden Ear Tritons 3+ 2 or 2+ or 1s you won't be disapointed.
