Custom Rotomolded Heavy-Duty Plastic Speaker Cabinet & Subwoofer Box Shell with Molded-In Brass Inserts for Professional Audio OEM/ODM

Engineered for rugged live sound, outdoor events, and high-performance PA systems, our Custom Rotomolded Plastic Speaker Cabinet Enclosure provides an acoustically optimized, tour-ready, and weatherproof housing solution for professional audio speakers, active subwoofers, and portable sound systems.

Manufactured from high-density, impact-resistant polyethylene (LLDPE/HDPE) via advanced rotational molding, this seamless, thick-walled cabinet eliminates structural vibration and air leakage common in traditional wood enclosures. The enclosure features precision molded-in brass threaded inserts around the front driver mounting flange and rear connection ports, ensuring airtight driver seating and vibration-proof assembly.

Designed with acoustic internal ribbing and ergonomic side handles, this durable speaker housing offers exceptional resistance to physical shocks, water, UV rays, and extreme temperatures. We offer complete OEM/ODM custom molding services, including internal acoustic chamber optimization, custom port cutouts, horn flare integration, and custom color options.
