  • 15" bass and mid-range speaker driver unit providing 98dB sensitivity and 

Frequency response and impedance curves

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. Continuous Power Rating is defined as 3dB greater than the AES rating
  3. Tested as per the EIA-426-A standard
  4. Measured on axis at 1W, 1m in 2Π anechoic environment.
  5. Xmax derived from: (voice coil winding width-gap depth)/2.
  6. Small signal parameters measured after unit subjected to pre-conditioning signal
