We develop the SP9 with experience of the “grand music hall” SR11, same crossover structure but simplified balanced armature to achieve mastering-grade balanced and precision with reasonable cost. SP9 Continues SWEEAR’s Reference class top tier technology, that uses multiple advanced electrostatic, BA and dynamic drivers, and new gen. quad-bore of IPP micro-acoustic. We developed a new extremely high frequency BA that perform clearly separation and rapid response. Like SR11, the electrostatic drivers give the ultimate transparency and layered soundstage.
