Audiofrog GS40 GS Series 4" Midrange Car Speaker (Pair)

Designed to be used in two- or three-way systems, the GS40 includes a non-resonant injection-molded ABS plastic and fiberglass vented basket. The 1” copper voice coil wound on a Kapton® former provides high power handling. A parabolic propylene cone ensures long-term reliability and provides the right compromise between compliance and stiffness for flatter high frequency response. The ferrite motor includes a neodymium bucking magnet atop the pole piece for increased motor strength and sensitivity. Terminals are secured by a small PC board integrated into the inside of the basket.

The GS40 is optimized for use in passive systems with the GS10 tweeter and GS410C passive crossover network. It can also be used in active systems or in a three-way system with the GS10 and GS60 midrange. For a combination of active and passive three-way system, use the GS40 with the GS10 and GS410C and a GS60.
