The H65A features a hard-anodized black aluminum cone and a die-cast aluminum alloy basket, minimizing unwanted resonances for clear and detailed sound reproduction. The 1" aluminum dome tweeter with a neodymium magnet ensures extended high frequencies with minimal distortion. The 18dB/octave crossover includes Rear Acoustic Fill (RAF) outputs, allowing for additional speakers to be connected without affecting impedance load, enhancing the stereo image and soundstage.
