3500 Series

SUPER SONIC

The 3500s are some of our most sonically accurate sub-drivers. This accuracy comes from a low moving mass, ultra-high energy design that uses a crazy strong motor combined with long gap/long coil topology, that you’ll find on our legendary 9500 and 9900 subwoofers.  Like their big brothers, the 3500 Series subs come with V-ROM surrounds, multi-layer spiders, 800-degree thermoset voice coils, and cast aluminum frames. All of these features combine to make the 3500 Series a brutally musical addition to our USA built lineup.

The 3500 Series features our Evolution Subwoofer Package (ESP). ESP equipped drivers sport a deeper frame than standard subs and an exclusive surround and cone designs. ESP subs are truly built to maximize performance in their designated size class.

The 3500 Series comes standard with an oversized dry finish black composite dust cap, red logo, and treated pulp cone, but it can be optioned out with alternative composite dust caps, composite cones, powder coated frames, supercharging, and a multitude of logo options to give your sub a personalized look and/or added performance for a specific application.
