12" Coaxial Ferrite Loudspeaker, 2.5" LF + 1.75" HF voice coil, 300 W + 40 W , 99 dB +106 dB

 

12CX1_copy

KEY FEATURES:

  • 99 db SPL 1W / 1m ( LF ) average sensitivity

  • 65 mm ( 2.5”) high temperature voice coil ( LF )

  • 600 W AES program power ( LF )

  • Triple aluminium demodulating rings

  • Single magnet assembly

  • Silicon spider

  • Water protected cone

  • 1” exit HF compression driver

  • 44 mm (1.75”) HF high temperature voice coil

  • 80 degrees nominal dispersion

 

Application: Stage monitors and compact bass reflex boxes.

The 12CX1 is a 12" / 1" coaxial transducer designed for use in compact reflex enclosures and stage monitors with a nominal dispersion of 80 degrees. The low profile, smooth curvilinear LF cone provides smooth response within its intended frequency range and water prove protective coating, allowing application in a wide range of environments. The state-of-the-art 65 mm (2.5 in) LF voice coil has Kapton former, which together with high temperature resistant resin ensure high reliability by high power.

A triple aluminium demodulating rings on the magnet structure reduce distortion and inductance and improve transient response.

The 1" exit compression driver adopted is our D2544 model. The HF driver diaphragm assembly, using triple layer polyester dome this together with phasing plug improve linearity of frequency response in high end.

Because of design with single magnet assembly the speaker has light weight and compact size.

1. AES standard. Power is calculated on rated minimum impedance. Measurement is in 65 L box enclosure tuned 63 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.
