Podrobný popis

Koax. reproduktor 12"/1,4", 450/90W, 101/110dB, 40-20000Hz, X-max 5,5mm, vyzař.úhel 60°, hmotnost 5,9kg

• The CX12N351 is a top class coaxial design that provides an excellent frequency response linearity withvery low distortion.
• The CX12N351 is powered from an integrated high power neodymium magnetic structure that guarantee high dynamic and sensitivity for both components.
• The mid-bass section features a 3,5" inside-outside voice coil design that provides a very high power handling, especially in comparison to a standard 3" voice coil.
• Thanks to an integrated demodulation ring the mid-bass section gets a fastest time response and lower distortion.
• The compression driver use a 2.5" diaphragm with a 1.4" throat featuring several state of the art technologies. The diaphragm and suspension are formed from 0.05 mm thick pure titanium
