Description

The aluminium cone on this driver is extremely rigid yet well damped, making the bass and midbass region very clean and low in distortion. When used with a well-designed crossover, an extremely flat frequency response can be achieved that is clean well into the midrange region.

Features

  • Great looking and sounding woofer
  • Cosmetic stamped steel frame
  • Flat frequency response in passband region
  • Impressive output capabilities when used in MTM designs
  • Very low distortion
