Features

  • 15" bass/mid-range driver offers 250Wrms (AES standard) power handling and 100dB sensitivity
  • 2.5" high-temperature copper voice coil wound on polyimide for increased reliability
  • Compact and lightweight neodymium magnet assembly
  • Smart use of venting and specially designed heatsink for reduced thermal compression
  • Effective flux management enables increased sensitivity

8Ω Frequency Response

Product Graph
  1. Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.
  2. Measured on axis at 1W, 1m in 2π anechoic environment.
  3. Xmax derived from: (voice coil winding width-gap depth)/2.
  4. Small signal parameters measured after unit subjected to pre-conditioning signal.
