6" x 9" (25mm) Mittelton Lautsprecher
Designed to be used in two- or three-way systems, the GS690 includes a non-resonant injection-molded ABS plastic and fiberglass vented basket. For a 2-Way system, use a GS10 tweeter and a GS610C crossover. You can also use the GS690 with a GS42 and an active crossover, or with a GS10, GS40 and GS410C with an active crossover between the GS690 and GS40.
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.
