The Axi2050 is a high power, high-output driver which reproduces a frequency range of 300Hz-20,000Hz without the need for a midband crossover. The Axi2050 delivers an exceptionally coherent signal, particularly in the critical listening band; and an extended frequency range: enhancing clarity and speech intelligibility, as well as reproducing music more dynamically and with greater coherence.
In contrast to most existing high-sensitivity, wideband drivers which are designed with two separate diaphragms, the Axi2050 uses a single, large diameter, sculpted, circumferentially axiperiodic, annular titanium diaphragm. This breakthrough technology enables the device’s remarkable wideband output, as well as providing a number of other significant advantages.
The result of more than five years’ research, the Axi2050’s patented diaphragm design consists of many curved, axiperiodically symmetrical elements which adds immense strength to a very thin and light sheet of titanium. Consequently the shape of the mechanical vibration modes are tailored so they do not couple with the acoustic modes; enabling the device to deliver a very uncolored performance by avoiding resonance peaks.
This single diaphragm has a diameter large enough (more than 175mm) to reproduce frequencies as low as 300Hz, while still having a small enough moving mass to facilitate high frequency reproduction. And the diaphragm's large surface area and axial flexibility enables the generation of very high SPL, even at low frequencies.
"We are very pleased to have the NAMM 2019 debut of the Axi2050. The R&D team at Celestion worked for several years using mathematical tools and modeling software in optimizing the design of the ultimate, single diaphragm compression driver,” explains Ken Weller, Marketing Manager at Celestion. “As a result, the Axi2050 driver is able to deliver absolutely optimum performance over a very wide frequency range.”
According to Celestion, the Axi2050 delivers unrivaled intelligibility and perceived audio performance, particularly in the critical listening band. The large, single diaphragm device also features a high sensitivity output of 140dB (measured at 1W on a plane wave tube), with 115dB-120dB (anticipated) on an appropriate large format, 2-inch exit horn, plus 150Wrms (AES standard) of power handling capability.
The Axi2050 is now production-ready and also offers a fully scalable technology. More information on the Axi2050 is available here: https://celestion.com/product/174/axi2050/
Celestion will attend the 2019 Winter NAMM with two booths: #7602 located in in Hall C, and #18100 in the Pro Audio Hall (ACC North, Level 2).
