- 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
- Double silicone spider assembly for improved excursion control and linearity
- Water protected cone with carbon fibers
Application : Power bass
The 18XB1500 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 result is high efficient transducer for bass horn applications, with the ability to handle high excursion with low distortion and reduced thermal power compression.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 180 L box enclosure tuned 43 Hz using a 40-400 Hz band limited pink noise test signal applied continuously for 2 hours.
2. Program power is defined as 3db greater than AES Power Capacity.
* Linear Mathematical Xmax is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg is the gap depth.
