The aforementioned Vandersteen 2CE Sig IIs are another must audition in this price range but are not as efficient.I'd take it even farther, the 2Ce Sig II is a must-audition up $5K. I drove mine to satisfying SPLs with my Ayre AX-7 (60 W into 8 ohm, 120 into 4 ohm). I only heard clipping if I tried to reproduce The Who at concert levels. Anyhow, the 2Ce is superbly balanced in it's price category without any substantial weakness.
