Oberton 18NXB1601 - 18" 1600W 8 Ohm

The 18NXB1601 neodymium bass loudspeaker is specially designed for horn application to deliver very high impact bass response, with exceptional high power capacity. It incorporates an 4.5" sandwich voice coil, two double silicone spider assembly, paper cone with carbon fibers and die cast vented aluminium frame. Powerful, vented neodymium magnetic structure with massive heatsink and double demodulating rings reduced power compression. The result is high efficient transducer for bass horn applications, with the ability to handle very high excursion with low distortion and reduced thermal power compression.
