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.
