The 18XB1500v2 ferrite 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, double silicone spider assembly, paper cone with carbon fibers and die cast vented aluminium frame. Powerful, vented magnetic structure with double demodulating rings reduced power compression.The top and back plates are treated with special high quality epoxy electro-deposition coating, which extremely improves the corrosion resistance of the speaker. The result is high efficient transducer for bass horn applications, with the ability to handle high excursion with low distortion and reduced thermal power compression.
Features:
- 115 mm (4.5") high temperature sandwich voice coil
- 3000 W AES program power
- Powerful, vented 245 mm magnet structure
- Double aluminium demodulating ring for lower distortion and improved heat dissipation
- Two double silicone spider assembly for improved excursion control and linearity
- Water protected cone with carbon fibers
- Epoxy anti-corrosion coating of top and back plates of the magnet structure
