With 100 watts RMS power handling and 300 watts peak power handling, the GB40 is built to deliver strong, controlled output when paired with a recommended crossover.
Built for Clean, Accurate Sound
The GB40 uses a treated paper cone, a 1" voice coil on a fiberglass former, and a milled flat single-layer CCAL voice coil to support smooth, precise performance. A copper inductance and distortion-reducing pole piece cap, along with the neodymium motor and bucking magnet, help the speaker deliver clean sound with less unwanted distortion. The flat progressive Nomex spider, nitrile butadiene rubber surround, and proprietary vented cast aluminum basket all work together to support dependable operation in demanding in-car environments.
