CT Sounds CT2X10 Dual 10″ Kerf Port Universal-Fit Car Subwoofer Box

By |2026-07-22T13:44:04+00:00July 22nd, 2026|

Product Description:The CT Sounds CT2X10 is a dual 10-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 9.45” cutout diameter make this pre-fabricated 10” 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 CT2X10 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 (2) flush-mounted black terminal cups. The terminal cups feature 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 cups creating a true plug-n-play product offering.

CT Sounds Single 12” 1300W Loaded Tropo Series Subwoofer Box – TROPO-1X12D2

By |2026-07-22T23:05:32+00:00July 22nd, 2026|

Product Description:The CT Sounds TROPO-1X12D2 is a pre-loaded single 12” ported car subwoofer box that takes the guesswork out of finding the perfect subwoofer and enclosure for your system. The bass package features our TROPO-12-D2 1300-watt max power 12-inch car subwoofer which comes pre-installed flush into the 1.25” front baffle using claw nuts and fasteners ensuring an air-tight seal. Additionally, the dual 2-ohm subwoofer is pre-wired inside the enclosure using 12 gauge ofc wire for a 1-ohm final impedance at the terminal cup. This is a true plug-n-play offering - simply run a +/- wire from the terminal cup to the +/- speaker terminals of your amplifier. The unique high-performance kerf-port, typically only seen in custom enclosures, allows the air pressure to exit smoothly and quickly creating extreme levels of responsive bass output. Furthermore, from the top to the bottom of the interior port walls is a 3-mm rabbet-groove that runs 80-mm into the port on the left/right interior port walls - this allows the premium black carpet to lay flush inside the port with zero-edge providing a smooth exit for the air and eliminating port-noise. Lastly, the enclosure was constructed using advanced joinery practices - dado joints connect the exterior left, right, top, bottom, and back wood pieces, 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 vibration. From the second you open the package, to the moment you pull the loaded enclosure out of the thick cardboard box, you will immediately recognize the craftsmanship and details that went into not just the secure packaging but the overall design of this product.
