Anyone have any experience with them. I am finishing my basement and starting my first home theatre. I am very new to this, but after researching I started auditioning tower speakers this weekend. I listened to Athena's(FS2's), Polk RTi8's, Klipsch RF2, and 3, and Sapphire ST2B's. The Sapphire's have built in subwoofers and I loved their sound significantly more than the others. However, I researched for a few weeks and have never heard of them. Anyone else have any expericences with these?
