T218 Sub Bass Loudspeaker


T218T218_1T218 • OVERVIEW

The Opus T218 is a 2000W, dual 458mm (18”) active

reflex loaded sub bass speaker. Their special design
results in a highly efficient 140dB peak SPL and very
high definition at low frequencies.

Very high forward gain and reverse attenuation ensures that very little sound escapes from the rear
of the cabinet, allowing extreme bass impact whilst avoiding outside environmental noise problems.

In touring systems there is little or no FOH sound at the monitor position.
The T218 is an ideal compliment for Opus 9 Series main cabinets.
