QF8 ? 8 inch dual cone 15 watt Speaker and Grill. The QF8 is a sensational, high sound quality dual cone speaker. Our goal was to achieve the sound of a ?co-axial? without the weight restrictions due to the heavy magnet typically associated with co-axial speakers. With its lighter weight, the QF8 is suitable for almost any ceiling and avoids any bowing of the ceiling. The QF8 features a 100 Volt line transformer with 15, 10, 5, 2.5 and 1.25 Watt taps.
