This 1' horn driver may be small, but it packs a big punch, providing 200 watts peak power. It's all because of the 21 oz. neodymium magnet with titanium diaphragm, ultimately achieving a frequency response of 2000 Hz to 20 kHz. The 1' flat aluminum voice coil provides rich mids and sweet highs. 205-type terminals, 8 ohm impedance. Fits horns with 1 3/8' x 18 TPI threads.
