The Penton Audio is a full-range weather-resistant mini speaker measuring just 6" x 9" x 6". Available in black or white, models include a constant voltage transformer, full-range 20-watt, 5" coaxial loudspeaker and a mounting bracket. As with most Penton products, it is strikingly handsome. Visually identical, the JD20X16 is 16 ohms. This model's shaped frequency response reproduces music with high accuracy, featuring polypropylene cone with rubber surround, high-temperature voice coil and a tweeter with Mylar diaphragm and neodymium magnet. Concealing a 70.7-volt transformer with screwdriver-adjustable taps, its ABS housing has UV inhibitors for long life without noticeable deterioration. For added strength, its grille screen is CRS and has an epoxy coating. Secured with a stainless-steel set screw, its patented aluminum mounting bracket allows attachment to single gang or double-gang box (patent applied for). The entire model is finished in your choice of white (-W) or black (-B). Connection is via chrome-plated push terminals.
