DC Audio Dual 15" Level 4 Ported Enclosure

Engineered specifically for the DC Audio Level 4 15" subwoofer, this ported enclosure delivers deep, controlled bass with a 7.0 cu ft net volume tuned to 32 Hz.

• Net Volume: 7.0 cubic feet. This airspace gives the woofer room to move at low frequencies, promoting deep bass without excessive compression.
• Tuning: 32 Hz. Sets the enclosure’s low-end response to reinforce strong, bass-forward notes while maintaining control at high output.
• Port Area: 101.4 sq in. A larger port area helps push air efficiently at higher power, reducing port compression for a cleaner bassão.
• Port Size: 19.5" x 5.2". Rectangular port dimensions are optimized for smooth air flow and consistent tuning across mounting variations.
• Cutout: 14.0". Precise mounting diameter to fit standard 15" drivers while preserving sealing integrity.
• Construction: 3/4" (18mm) Russian Baltic Birch – 13 ply. High-stiffness cabinet minimizes panel flex for tighter, more accurate bass.
• Front Baffle: 1" (24mm) solid front baffle – 17 ply. Adds rigidity at the woofer surface to reduce unwanted vibration.
• Bracing: 3/4" center baffle brace. Internal support reduces resonance and helps maintain consistent bass output.
• Finish: Carbon gray stain with polyurethane topcoat. Durable, show-ready surface suitable for high-end installs.
• Wiring: Pre-wired 10ga OFC with metal binding post. Easier installation with high-current readiness for powerful subs.
• Power Rating: Up to 3500W RMS. Designed to handle substantial continuous power without cabinet strain.
• Dimensions: Height 21.0", Width 40.0", Depth 22.2". A wide, balanced footprint intended for placement in a variety of vehicle trunks or cargo areas.
• Handcrafted in the USA: Built by hand in the United States with a show-quality finish and meticulous assembly.
