The Exotic F8 is a full range 8-inch driver designed for
smooth, wide frequency response, high sensitivity, and low distortion. The
special paper cone is embedded with papyrus fibers to optimize stiffness and
damping. An optimally matched whizzer cone extends high frequency response
beyond 10kHz. A special foam rubber surround reduces mass by 40% compared
with conventional rubber surrounds, resulting in higher sensitivity and
excellent damping properties. A totally new and proprietary spider design
dramatically improves the performance of this critical suspension part. By
combining an extremely open weave with a new resin formulation, all noises
normally created by the friction of the threads rubbing together are virtually
eliminated. Additionally, the open weave is highly acoustically transparent,
minimizing the reflections and resonances associated with conventional spider
designs.
A high
temperature copper voice coil is wound on a rigid, non-conductive glass fibre
former. The magnet system uses an Alnico V ring magnet for high sensitivity,
excellent stability, and low distortion. A copper cap on the pole piece,
combined with an under hung voice coil reduces non-linear distortion to a
minimum. New H2 lead-out wires eliminate noise due to roping and
resonances.
The frequency responses above show measured free field sound pressure in 0,
30, and 60 degrees angle using a 60L closed box. Input 2.83 Vrms, microphone
distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in
infinite baffle based on the parameters given for this specific driver. The
impedance is measured in free air without baffle using a 2V sine signal.
