The Alpha 65 performs just as well with instrumental music as with electronic music and is characterized by its great versatility. This model is composed of a 6.5" (16.5cm) woofer/mid-range speaker with a polyglass cone loaded in a large laminar port associated to a 70W amplifier and of a 1" (25mm) aluminum inverted dome tweeter (35W amplifier). Alpha 65 has a frequency response of 40Hz to 22kHz (+/-3dB).
