Details

About this product.

Design

A single 21 in neodymium driver has a 4 in ISV voice coil, a large-displacement suspension and a composite-reinforced, water-repellent cone. It delivers clean, undistorted low end at very high SPL.

Driver technology

The motor uses a high-grade neodymium magnet in a structure optimized for thermal and magnetic efficiency. A straight-ribbed composite cone and Double Silicon Spider (DSS) give ultra-linear piston action and full mechanical control. The 4 in (100 mm) Interleaved Sandwich Voice coil (ISV) adds thermal stability, durability and a very high force factor.

Cabinet and use

The phenolic birch plywood cabinet has a pole mount socket, stacking feet, flush handles and heavy-duty wheels. It pairs with any ED point source or Axiom line array loudspeaker. Its small size fits tight venue spaces.
