DC Audio Dual 12" Level 4 Ported Enclosure

DC Audio Dual Level 4 12" Ported Enclosure is a handcrafted, 3.0 cu ft ported enclosure tuned to 33 Hz, built specifically for the DC Audio Level 4 12" sub to deliver deep, controlled bass. Made in the USA, it features a clean exterior with zero visible screw holes and airtight joints formed with Titebond III for long-term durability.

• Net Volume: 3.0 cubic feet — provides the internal airspace needed for the Level 4 12" to breathe at deep bass frequencies, supporting strong low-end extension.
• Tuning: 33 Hz — targets responsive, low-frequency output with a focus on deep bass without excessive midbass boost.
• Port Area: 43.2 sq in — larger port area facilitates air movement at high output, helping maintain enclosure efficiency at volume.
• Port Size: 13.5" x 3.2" — dimensions chosen to balance tuning and port velocity with the enclosure size.
• Cutout: 11.0" — accommodates the Level 4 12" sub mounting hole diameter for a secure fit.
• Construction: 3/4" (18mm) Russian Baltic Birch — 13-ply plywood delivers rigidity and reduced panel resonance under high power.
• Baffle: Front 1" (24mm) solid baffle — adds stiffness to prevent flex and maintain consistent alignment of the woofer.
• Bracing: 3/4" center baffle brace — reinforces the enclosure structure against internal panel movement when driven hard.
• Finish: Carbon gray stain with polyurethane topcoat — durable, show-quality appearance compatible with custom installs.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies installation and provides robust conductor paths for high-power use.
• Power Rating: Up to 3500W RMS — supports high-power Level 4 configurations with ample headroom.
• Dimensions: Height 15.0", Width 31.5", Depth 19.0" — size to fit typical trunk or cargo compartments while maintaining performance.
• Handcrafted in the USA — built by hand in the United States with careful craftsmanship and tight tolerances.
• Airtight Integrity: Fully glued with Titebond III — reduces leakage for predictable bass response over time.
• Ready to Install — arrives wired and prepared for sub connection; no additional exterior modifications required.
• Lead Time: Built to order; ships in 2–3 weeks — plan accordingly for production and delivery.

This enclosure is ideal for a dedicated, high-power dual 12" setup where the goal is deep, confident bass with a rigid, air-tight enclosure that maintains performance under demanding playback — all while presenting a clean, show-worthy exterior.
