Beyma 12BR70

Beyma 12BR70 - 12" 125W 8 Ohm

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.
