round. Its free air resonance is comfortably below the
lowest frequency it is called upon to reproduce, and its
thermal design is correspondingly conservative, allowing a
continuous sine wave power rating of 150 watts continuous,
and 300 watts on program.
Both drivers share a massive magnetic structure
that generates a 14,500 Gauss field in the air gap, and a unique
bifilar wound voice coil minimizes non-linearity at the
maximum excursion. Both drivers share a moderately high
electrical efficiency that allows 107 dB SPL power output at
one meter distance with one watt input.
These drivers are not merely upgraded PA drivers
but are engineered from the frame upward to perform
reliably at high SPLs in their respective applications. They are
virtually indestructible, and their field failure record is
essentially zero when operated within their ratings.
