Ampere Audio AA-Encore 15″ D1 – 2500w RMS Subwoofer


SKU: AA-ENCORE-15 Category:

The Ampere Audio AA-Encore 15″ is our newest line up for subwoofers and all built in house. The Ampere Audio AA-Encore 15″ was designed for 2500w 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. One of the thickest 3” coils on the motor reduces energy storage from inductance, with the side benefit of lowering distortion for “faster” response.
