BROADBAND DIRECTIVITY MADE SIMPLE
S-series - the second generation of Passive End Fire Technology

 S18F and S18R

"S28 split in two"

S18 is unique combination of a horn-loaded S18F subwoofer and reflex-loaded counterpart S18R working together as a dual 18" passive cardioid subwoofer featuring Passive End Fire Technology.

Low frequency directivity control with ONLY ONE amplifier channel required - no bi-amp presets required!

Patented Passive End Fire Technology hybrid enclosure design for the most flexible passive cardioid sub system to date!

"Best from both worlds" Extremely accurate and dynamic low frequency reproduction!

Two S18F horn-loaded units option with one S18R reflex unit gives even more punch or "kick" with even better rear reduction.
