Main features:
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 efficient passive cardioid sub to date!
Integrated flying tracks on both sides and pole mount adapter.
"Best from both worlds" combining fast horn punch with warm infrasub rear reflex side.
Extremely accurate and dynamic low frequency reproduction due to symmetric twin horn channel design with double long excursion 18” neodymium cone drivers, one each side.
