Why pay more? The GRS 3FR-4 is a great replacement driver for the widely-used, 3"-size full range drivers found commonly in home theater systems, table radios, “sound bars”, and multimedia speaker systems, among many other uses. It’s also useful as a replacement for 3" woofers.


A sturdy stamped steel frame with “pincushion”-shaped mounting flange supports a robust ferrite ceramic magnet, and the coated paper cone with foam surround delivers clear sound that you might not expect from a driver this affordable.
