I shared a flat in London years back with a friend who had a pair of SL3s and later swapped them for the slightly smaller Aerius i. They were not bright to my ears, in fact I really liked the top and mid, but the bass was truly awful. They really behaved like two totally unconnected speakers, the change over from panel to moving coil bass unit was glaringly obvious and they seemed utterly incapable of playing in time or in tune as a result. I hated them, but I would like to hear the full range ML stat, the CL2Z or something as taken in isolation from the flubby bass driver the panels of both speakers were IMHO something special.
