Celestion - AN2775 20W 8ohm - Compact Full Range Loudspeaker - Neodimio

Features

- Compact and lightweight, full-range neodymium loudspeakers

- Advanced Finite Element Analysis techniques used for acoustic, mechanical and electromagnetic modelling

- Ideal for applications such as portable line arrays where actively controlled wavefront (beam steering) is used

- Delivers wider dispersion to higher frequencies than many equivalent compact, full-range drivers on the market

- Chassis purpose-designed for maximum free air movement, with square mounting frame to facilitate close coupling of multiple units

- Stiff and light aluminium cone remains rigid to higher frequencies, delivering a smoother response in the critical listening band

- Half roll elastomer surround provides damping for unwanted resonances and sustained centring control at extremes of excursion

- Designed to be weather resistant for outdoor applications

Note

(1)Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.

(2)Measured on axis at 1W, 1m in 2pi anechoic environment.

(3)Xmax derived from: (voice coil winding width-gap depth)/2.
