I've auditioned the Legacy line-up twice - largely because there were qualities I liked a lot about them and some that I really didn't. I understand why so many people are happy with the speakers, they are definitely a "rocker's speaker" and I'd recommend anyone to audition them. But, with that said, I didn't end up buying them.
First, I felt the Focus was the sweet spot in the line-up. I didn't like the new Empire speakers - they were not natural sounding to me. And, the Whispers are just not a real-world speaker for my home (speakers too big).
I thought there were significant benefits of the Focus versus the less expensive speakers, particularly in the area of mid-range and vocal transparency.
If you love rock, love moving a lot of air, this speaker will immerse you in the sound. And, if you want a fairly revealing mid-range, then the Focus may be the speaker for you.
My problems had to do more with coherence and the boom. But, everything is a trade-off. If you end up getting them, enjoy.
By the way, I ended up going a very different direction than the Legacy. After auditioning Thiels, Revels, B&W's, Ariels, Dynaudio, etc. over a two year period I narrowed my search down to Revel and Harbeth's. If you like the full sound of the Legacy, you may love the Revels (which I did), and I strongly recommend them. But, I ended up with the Harbeth's 7ES. It's a much smaller speaker, but I love the mid-range. I heard the Red Rose the other weekend in NYC and found them an even more revealing speaker. I loved them, but they were another $1,000 more than the Harbeths ($2,400).
