Don't forget about the importance of the Ultralam baffle that is used on the x2 and x5. It goes a long way in keeping unwanted resonance and coloring of the music. Before I purchased my X5's I had heard the x2 as I was prepared to buy those. But there was just something that wasn't quite right. Granted, it was at someone's house and perhaps the supporting equipment wasn't right, or maybe the placement and room acoustics could have been better, but I ended up buying the X5's and, after trying a couple different amps and working with room treatments and placement, I couldn't be happier. I will also tell you this, I haven't owned a pair of box speakers in almost 30 years, and never will. Dipoles and OB's do it for me.
