This enclosure is designed for show-quality, high-power DC Audio installations, delivering deep bass with tight control in a ported configuration. The 8.5 cu ft internal volume and 31 Hz tuning promote substantial low-end output while maintaining stability at high excursion. The rigid Baltic Birch construction, thick front baffle, and internal bracing minimize cabinet flex and resonances, preserving the subwoofer's transient response. Pre-wired 10ga OFC wiring and metal binding posts simplify wiring, while the glued, airtight build with Titebond III ensures long-term durability. The carbon gray finish provides a durable, visually clean enclosure ready for showroom or trunk installs. Lead time is 2–3 weeks from order.
