Oberton 15MB35 - 15" 700W 8 Ohm (Ferrite)
15MB35 loudspeaker combines good linearity and efficiency with high power handling capabilities, with use of 88 mm aluminium voice coil and silicone spider. It features aluminium die cast frame, vented ferrite magnet structure with two demodulating rings. 15MB35 is suitable for application in a wide variety of enclosure types and particularly as LF driver in 2- or 3- way boxes. New 3.5" voice coil reduces power compression at high power handling compared with classic 3" voice coil.
