Ampere Audio AA-4.0 | 3800w Premium Subwoofer

The AA-4.0 Series is our newest line up for subwoofers and all built in house. The lead wires are formed into the spider layers which enhances durability and eliminates lead slap/breakage problems. The frame is cast aluminum with a sandblasted, powder coat finish. A large 3” Copper coil in the motor reduces energy storage from inductance, with the side benefit of lowering distortion for “faster” response. Large 199 mm triple-stacked, high-energy Y35 ferrite handle the heavy lifting and bring QTS down to a level where the subwoofers can be used in small vented or sealed enclosures.
