Sundown Audio SA Classic 15" 1000W RMS 2-Ohm 2.5" DVC Subwoofer CLASSIC-15-D2
This Listing Includes:
- (1) Sundown CLASSIC-15-D2 Subwoofer
The Sundown Audio SA Classic 15 D2 subwoofer is a heavy-hitting 15-inch driver designed for enthusiasts who want big power handling, deep excursion, and flexibility in box design. Rated at 1000 watts RMS and 2000 watts peak, the SA Classic 15 D2 delivers serious low-frequency output while keeping control and sound quality in mind.
At the heart of the SA Classic 15 is a custom 2.5-inch voice coil built into a low-distortion motor with a large aluminum Faraday ring. This helps smooth the acoustic response and reduce inductive distortion, especially at high power. A robust double-layered Nomex spider and SPL competition-grade paper cone are designed to survive aggressive daily listening and competition-style abuse.
The high-strength cast aluminum frame provides a rigid foundation for the motor and moving assembly, while integrated venting helps keep the coil cool. High-temperature voice coil wire, stitched-on XL tinsel lead wires, and spring-loaded terminals add up to a durable, installer-friendly subwoofer ready for real power.
The SA Classic 15 D2 is optimized to work in multiple enclosure types. Sundown recommends a 3.5 cubic foot ported enclosure with 35 square inches of port area tuned to 35 Hz for strong, musical bass. For a tighter response and a smaller footprint, a 2.5 cubic foot sealed enclosure works well. For advanced builders, detailed 4th-order band-pass specs are provided, including a 1.5 cubic foot sealed chamber and a 4.5 cubic foot ported chamber with 90 square inches of port area and a 6-inch port length, allowing you to squeeze maximum output and bandwidth from the driver.
Whether you are building a loud daily driver, a demo vehicle, or a budget-friendly competition system, the SA Classic 15 D2 combines value, power handling, and deep excursion in a flexible package that performs in many box designs.
