Components
Low Frequency-Bass
material is reproduced by a powerful,
long excursion, 12-inch loudspeaker having a 3-inch diam-
eter edgewound copper ribbon voice coil operating in a
magnetic field of 10,400 gauss. The magnetic assembly,
energized by an Alnico V magnet, weighs 6.75 pounds: free
air resonance is 22 Hz. The surface of the cone is coated
with an exclusive damping formulation that provides mass
and density to optimize bass performance, prevent spurious
resonance and provide smooth performance extending into
the midrange region.
