The CVi-218S (Contra-Sub) is a portable, dual eighteen inch dedicated
subwoofer system designed to extend and supplement the low frequency
extension of CVi full range systems in live music and playback applications.
The CVi-218S features two high power, cast frame eighteen inch transducers
with 3” voice coils for extended use during high SPL applications. Steel
handles and pole mount cup are also featured for use as a base for pole
mounted full range systems. This configuration allows the two drivers to work
together in the same acoustic space to reduce distortion components caused
by driver mechanical non-linearity when the system is driven at high levels.
The result is cleaner, smoother low frequency reinforcement at higher SPL
levels.

Graphical Data NOTES:
1. Frequency Response: Variation of dB SPL versus frequency.
Normalized to 0dB SPL, 1/3 octave smoothing applied.
2. Horizontal Directivity: Variation of dB SPL versus frequency
and horizontal off axis angle. Normalized to 0dB SPL, 1/3
octave smoothing applied to reduce insignificant details.
3. Vertical Directivity: N/A
4. Impedance magnitude: N/A
