Optimus 1150 (400-1155) Features Faxback Doc. # 7645 The Optimus-1150 Lacquered Walnut Speaker System is a dual-woofer, two- way, bass reflex system. It has an excellent low-end response and yields greater efficiency and lower distortion when compared to accoustic- suspension or single woofer systems. A 3-inch wide dispersion tweeter provides higher sound pressure levels per watt, allowing you to use lower powered receivers or to drive you existing high-powered amplifier more conservatively. This means that the amplifier is less likely to clip or distort, which results in cleaner sound. The speaker cabinet is solidly contructed and is finished in lacquered walnut veneer. The removable decorative grille is acoustically transparent. (LB/all-09/20/94)
