PART NUMBER: 11118F0408
Application : High Power Bass
The 18XB1201 is new version of 18XB1301 . It is ferrite bass loudspeaker is specially designed to deliver very high impact bass response, with exceptional high power capacity. It incorporates an 4” sandwich voice coil with split winding , double silicone spider assembly, carbone paper cone and die cast vented aluminium frame. New powerful, vented ferrite magnetic structure with triple demodulating rings which reduced power compression and dramatically reduse THD. 18XB1201 is with reduced Mms which gives very fast response. The result is high efficient transducer for subwoofer applications, with the ability to handle very high excursion with ultra 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.
