The Prime Tower is a reference-grade speaker with pinpoint accuracy, exceptional tonal balance, effortless bass response, and all the qualities of the best high-end floorstanding speakers available. It's truly an impressive achievement for two-channel audiophiles or surround sound home theater systems alike, especially considering the reference configuration performance value.
Carefully crafted for acoustic excellence, the 4.5-inch midrange driver is mounted in its own dedicated, fully-sealed compartment to ensure a smooth, accurate, and clear midrange without coloration. The cone material is extremely light and rigid and maintains a flat frequency response with excellent handling in the fundamental midrange frequencies.
Dual 6.5-inch woofers deliver deep, articulate bass effortlessly to set the mood and accentuate the bass impact of instruments, bass lines, and movie sound effects. Each woofer has a separate internal compartment in the cabinet with its own custom port tuning frequency. The result is deep, powerful and accurate bass that is heard and, more importantly, felt.
The Prime Tower speaker's 1-inch aluminum dome tweeter is lightweight, efficient, and rigid, reproducing crystal clear clarity at loud volumes. The clarity offers a sense of complete transparency, while delivering an "airy" presentation and incredibly revealing highs so female vocals and dialogue always sound crisp and smooth.
