CT1X12 // Single 12” Kerf Ported Universal Car Subwoofer Box

The CT Sounds CT1X12 is a single 12-inch empty car subwoofer box engineered for maximum bass response and low-frequency reproduction. The kerf-style port, universal fit, poly-filled lined internal walls, and 11.34” cutout diameter make this pre-fabricated 12” subwoofer enclosure compatible with a wide variety of subwoofer brands on the market. Its kerf-style port, typically only seen in custom enclosures, will “unhide” the missing bass in your system and have your subwoofer playing deeper and more accurately.

The CT1X12 subwoofer box was constructed using some of the most advanced joinery practices - dado joints connect the exterior left/right wood pieces to the exterior back/top/bottom wood pieces by a groove, and miter joints connect the corners of the box by cutting the wood at a 45-degree angle. These joinery practices ensure maximum surface contact and eliminate any concern for vibration. Additionally, the recessed side panels further enhance the air-tight, vibration-free construction design.

To finish the equation, the subwoofer box is wrapped in a premium-grade black carpet with a flush-mounted black terminal cup. The terminal cup features 8-gauge push-terminals labeled with red & black stickers identifying positive and negative connections. Internally, the subwoofer box comes with 12-gauge speaker wires that are pre-soldered to the terminal cup creating a true plug-n-play product offering.
