DC Audio Single Level 4 12" Ported Enclosure is a purpose-built, 1.75 cu ft ported cabinet engineered specifically for the DC Audio Level 4 12" sub, delivering deep, controlled bass with a 33 Hz tuning.

• Net Volume: 1.75 cu ft — Provides the tuned airspace that the Level 4 12" sub needs to achieve deep bass without excessive box coloration.
• Tuning: 33 Hz — Sets the enclosure’s low-end extension and port behavior to produce articulate bass at high output levels.
• Port Area: 25.31 sq in — Sufficient vent area to move air efficiently at the tuned frequency, helping maintain linear response as you push the sub hard.
• Port Size: 13.499" x 1.875" — Slot port dimensions selected to achieve the 33 Hz tuning with minimal port noise.
• Cutout: 11.0" — Mounting opening sized to fit the target 12" subwoofer for a clean, reliable install.
• Construction: 3/4" (18mm) Russian Baltic Birch — 13-ply construction provides stiffness and durability to minimize panel flex and peak smearing.
• Baffle: Solid 1" (24mm) front baffle — 17-ply front surface enhances rigidity and reduces resonance transfer to the enclosure.
• Finish: Carbon gray stain with polyurethane topcoat — Durable, show-quality exterior that resists wear in a vehicle environment.
• Wiring: Pre-wired 10ga OFC with metal binding post — Simplifies installation with ready-to-wire connections and solid terminal hardware.
• Power Handling: Up to 1750W RMS — Supports high-power amplification within the enclosure’s design envelope for loud, musical bass.
• Dimensions: Height 15.0", Width 22.0", Depth 17.0" — External footprint to plan fitment in trunk or cargo areas.
• Handcrafted in the USA: Built by hand in the United States with zero exterior visible screw holes and fully glued with Titebond III for airtight integrity and durability.
• Lead Time: Built to order. Ships in 2-3 weeks.
