Sigma S215
3-Way Active Speaker 2 x 15“/1.4“, 1400 W
Many venues demand high SPL and low-ranging response. However, a 
fullrange enclosure is often the only viable option for some of these 
applications. Loaded with two 15“ woofers designed to handle consi-
derable loads, the S215 is the solution of choice for such scenarios.
The S118 is a powerful, active 18“ subwoofer housed in a bassreflex en-
closure. Designed specifically to provide low-frequency support for high-
performance S115 fullrange speakers, it packs a mighty low-ranging bass 
punch. S118 and S115 enclosures have the same width so they are easily 
stacked to set up professional-grade PA systems.
