J&M® performance XT series is the best and most powerful speaker available for the GL1800 06-17 and F6B fairing. It has a complete redesign for 2016, the high-output fairing speaker upgrades are manufactured a full 10 mm’s larger in cone diameter than stock, while still retaining the same exact dimension mounting hole pattern and electrical spade lug size/polarity, to make installation a snap. Rated at 3 ohms impedance and 140 watts maximum power, they feature a very thin, hard, injection molded polycarbonate cone, titanium colored dust cover, super flexible rolled edge, high sensitivity voice coil and dual-donut design high flux strength Neodymium magnet structure, to provide for maximum air movement, along with superior bass and midrange response. Fits the GL1800 06-17 and F6B fairing (except Euro Model GL1800). Pair.
