The Colossal Sounds Mammoth subwoofer is an absolute power house. This ultimate subsonic driver is unmatched in performance and output. This SPL subwoofer was designed and engineered to withstand brutal, all day torture while maintaining incredible output and efficiency.

Featuring a high temperature 4″ flat wound 4-layer voice coil, throw everything you have at the MA-Series as long as your vehicle can handle it. We engineered a grade Y35 ferrite motor with triple 1″ stacked magnets, a custom top plate for an extended flux field and a drilled bottom plate for optimal cooling. By using a non-pressed paper cone with a glossy carbon fiber dust cap and combining it with our dual-layer 100% nomex spider pack with triple sewn in heavy duty lead wires, we are able to maintain complete cone control and accuracy across all frequencies and power ranges. Encased in a cast aluminum basket optimized for cooling, the MA-Series subwoofer can be heard well before seen.
