This 4-ohm sub is the single-voice-coil cousin to the TS-W1241DVC. Aside from that difference, the TS-W1241C boasts the same exceptional features, specs, and performance. Examples? A fearsome 1,000 Watts of music power (max.), Pioneer's Voice Coil Cooling System for lower sub temps and extended sound quality, and an aluminum insert that increases the rigidity of an already super-strong cone. If you're looking for a combination of skull-bombing power and precise musical control, the TS-W1241C is a great choice.
