Celestion blows the Big Red Horn

The Big Red Horn has a 2-inch throat exit with a 90° x 45° radiation pattern

Celestion has unveiled the Big Red Horn with the Axi2050 wideband axiperiodic compression driver. This bespoke horn, constructed using a fibreglass compound and available in alternative colour options, has been specifically designed to optimise the Axi2050’s wide bandwidth performance. The Big Red Horn has a 2-inch throat exit with a 90° x 45° radiation pattern and cut-off frequency of 400Hz.

As for the Axi2050, it is built to reproduce a maximum frequency range between 300Hz and 20kHz without the need for a midband crossover. Rather than employ two separate diaphragms, the wideband axiperiodic compression driver uses a single annular titanium diaphragm that is large in diameter (175mm) and circumferentially axiperiodic. The diaphragm comprises several curved, axiperiodically symmetrical elements, adding strength to what is a light, thin titanium sheet. Due to its unique shape, mechanical vibration modes are tailor-made to not couple with the acoustic modes, which allows for the avoidance of resonance peaks, resulting in an uncoloured performance.


Also new is the CDX14-3040 neodymium magnet compression driver. This features a 1.4-inch exit and 3-inch voice coil. The edgewound coil copper clad aluminium voice coil reportedly delivers 75Wrms of power handling and has a sensitivity of 106.5dB from 500Hz to 20kHz. The CDX14-3040 is Celestion’s third large-format compression driver to include a 3-inch single-piece titanium diaphragm and surround.
