37Hz Dual Slot Port Power in a Compact Design

Built for U.S. car audio enthusiasts who crave fast, tight bass response, this enclosure is precision-tuned at 37Hz to deliver energetic, punchy low-end performance for everyday listening. Its dual precision slot port system improves airflow efficiency, reduces distortion, and produces louder, cleaner bass output with impressive clarity. Designed with a 7 1/8” cutout, it’s perfect for compact subwoofer setups while still delivering strong, impactful low-frequency performance that hits far beyond its size.

Lightweight Power with Tight, Accurate Low-End Performance

Engineered for clean and controlled bass, this enclosure features an optimized 1.46 FT³ air chamber that enhances accuracy while delivering strong output efficiency and tight low-frequency response. Built from durable 5/8” high-quality MDF, it provides solid structural strength and reduced vibration for consistent performance even during heavy bass use. Despite its rugged construction, the lightweight 35 lb design makes installation quick and easy, offering the perfect balance of portability, durability, and sound quality.

Airtight Engineering with Pro-Grade Connectivity

Designed for a clean and professional install, this enclosure is wrapped in rugged trunk liner carpet that delivers a factory-style finish seamlessly blending into modern American vehicles. Its industrial sealing and bonding system uses premium Titebond silicone reinforced with Titebond wood glue, ensuring airtight construction for maximum bass efficiency and long-lasting durability. Equipped with dual spring-loaded terminals, it provides fast, secure, and reliable wiring connections built to support demanding high-performance audio systems with ease.
