Basshead Supply Single 15" 3.5 Ported Enclosure

Handbuilt single-15" ported enclosure tuned to 31 Hz, designed for 15" drivers requiring deep, punchy bass with precise control. Built in the USA from Russian Baltic Birch, it features a clean exterior with zero visible screws and airtight joints for long-term durability.

• Net Volume: 3.5 cubic feet. This internal air space supports robust bass performance from a single 15" sub while maintaining structural integrity and controlled excursion.
• Tuning: 31 Hz. Port tuning at this frequency emphasizes deep bass extension and transients, delivering punch without excessive rumble at typical listening levels.
• Port Area: 50.38 sq in. A larger port cross-section helps move air efficiently, supporting sustained low-frequency output with lower port velocity noise.
• Port Size: 15.502" x 3.25". Rectangular port dimensions balance air velocity and output to minimize port chuffing while maximizing bass under load.
• Cutout: 14.125". This mounting hole diameter is compatible with most 15" drivers, ensuring a snug, sealable fit.
• Construction: 3/4" (18mm) Russian Baltic Birch - 13 ply. Dense, rigid walls reduce cabinet flex for cleaner bass and better transient response.
• Baffle: Solid 1" (24mm) front baffle - 17 ply. Extra thickness reinforces sealing and minimizes front-baffle resonance for tighter midbass.
• Finish: Carbon gray stain with polyurethane topcoat. Durable, show-ready appearance that stands up to wear in a vehicle or showroom.
• Wiring: Pre-wired 10ga OFC with metal binding post. Ready-to-wire design simplifies installation and provides a solid, low-resistance connection.
• Power Rating: Up to 1750W RMS. Designed to handle high-power subs without compromising enclosure integrity or bass control.
• Dimensions: Height 17.0", Width 30.0", Depth 20.0". External footprint provides a substantial internal volume while fitting in typical trunk or cargo spaces.
• Handcrafted in the USA: Every enclosure is built by hand in the United States, with a focus on precision and quality control.
• Exterior screw-free finish: Zero visible screw holes on the exterior for a clean, showroom-quality look.
• Glue and joints: Fully glued with Titebond III for airtight integrity and long-term durability.
• Ready to install: Arrives ready to install—just wire up your subwoofer and enjoy.

In a car audio build, this enclosure excels in single-sub setups where space is at a premium but you demand deep, controllable bass. The combination of 3.5 cu ft net volume, 31 Hz tuning, rigid Baltic Birch construction, and a clean, screw-free exterior makes it a purpose-built solution for TROUBLE-free, show-ready installations.
