TroubleMaker. The name says it all. After causing trouble in the competition lanes and exceeding global expectations, we gained the knowledge necessary to tweak these subs and achieve the best results. After years of research and development, we designed a new technology in SPL competition subwoofer motors and restructured the whole line. With authentic red Kevlar cones, voice coils made in the USA, and a secret compound formula for the glues and resins, we combined the highest quality materials into our classified design. The result; a monster subwoofer that can handle up to 30K watts in burps and exceeds all specifications desired by competitors around the world.
