Details
A single S4S subwoofer system meets THX® Select requirements for a 3000-cubic-foot room. However, to meet THX Ultra2™ requirements for a
3000-cubic-foot room, two or more S4S subwoofer systems are required, using a total of four woofers. For every additional 3000 cubic feet of room
volume, it is recommended that one additional S4S system be added.
