This 12" bass loudspeaker has been specifically designed to deliver exceptional low frequency reproduction, with high sensitivity and extremely low distortion. It incorporates a curvilinear cone attached to a rubber surround, in order to provide suspension stability and to allow maximum excursion linearity. By combining a powerful magnet construction with a cast aluminium basket, the 12BR70 achieves high power capacity, and consequently, contributes to reduce the thermal power compression.

Key features:
  • 125 WRMS power handling
  • Sensitivity: 93 dB @ 1 W @ 1 m
  • 2” copper voice coil
  • Extended controlled displacement: Xmax ± 8 mm
  • Low resonance for low frequency extension
  • Flat frequency response and low distortion
  • Rubber surround
  • Die cast aluminium basket
  • Ferrite magnet
