Key Features
4",full-range neodymium loudspeakers,Compact and lightweight
88dB sensitivity in 1w/1m,40W power handing
25mm(1 inch),copper voice coil wire and polyimide voice coil bobbin,can endure high temperature.
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.
