just got my new YST-SW315 to replace YST-SW105 I was runnig with the SW-315 I aready had. They sound great togeather.Room is only 17X13X8 more than enough bass for that sise area.They also blend in well with fronts studio 100 v5s.I know there not svs,hue, velodyne etc;but they do sound pretty good especially for the price.
