Indy M is a great sounding, high power midrange and midbass designed to slay the competition! Using custom designed coils and spiders tuned to each exact model we were able to develop for excellent reliability and performance while implementing measures to increase the frequency response. These are great for small or large door builds in the car or studio in a 2 way mid top box with an appropriate tweeter and crossover. The large high temperature voice coil with integrated Faraday ring on the VC is supported by a dual roll treated cloth surround and a heavy duty cloth spider. A dimpled textured surface to the cone acts to increase the effective piston area in turn moving more air, creating more SPL. For keen enthusiasts looking for a lightweight and accurate sounding speaker the Indy M offers musicality and tough mid bass performance. It also has excellent detailed documentation making it easy to set up and use, as well as allowing the construction of more advanced projects.
