Original Opus SB218 subs but with a full exterior make over. Dual 18" drivers. New hard wearing hot applied scratch & water resistant paint. New internal wiring with NL4 connectors and new carry handles. New foam front with 3 original Beyma drivers and 1 driver replaced with Eminence Sigma Pro 18 but can't tell the difference between both cabs. Used recently. Sound great. 1000W 4ohm but recommend a 1200W amp.
