AMPERE AUDIO 2.5 6.5 INCH

The AA-2.5 RVE was designed for 500w rms per driver. The lead wires are formed into the spider layers which further enhances durability and eliminates lead slap/breakage problems. The frame is cast aluminum with a sandblasted, powder coat finish. A large 2.5” copper coil in the motor reduces energy storage from inductance, with the side benefit of lowering distortion for “faster” response.
