I heard the new speaker at CAF. Bass was tight and punchy. I did think the highs could sometimes be a bit much. I don't want to say bright but some of what I heard edged into that territory. Perhaps it was the recording or the associated equipment. I did hear another speaker using a concentric driver which didn't sound like this. Of course that was with different electronics but I thought it sounded much better than the SP 10. It also costs more than double the price.
