TRU SPEC ELITE Prefab Dual 8" Subwoofer Enclosure Sundown X

The TRU SPEC ELITE Prefab Dual 8" Subwoofer Enclosure is a pre-fabricated dual-8" box built for Sundown X and other high-performance 8" subs, delivering a precise 2.00 ft³ net internal volume tuned for deep bass with a 32 Hz ported response.

• External dimensions: 30.00" W × 13.00" H × 19.50" D — a compact footprint that accommodates two 8" drivers while preserving substantial internal airspace.
• Cutout: 7.45" cutout diameter — standard mounting hole size for common 8" woofers with secure installation.
• Material: MDF construction — dense, rigid panels that minimize panel flex for tighter bass articulation.
• Material thickness: 0.75" — thicker panels contribute to overall stiffness and durability in a prefab enclosure.
• Net Internal Volume: 2.00 ft³ (after factoring displacement for two subwoofers) — provides ample airspace for two 8" drivers within a single enclosure.
• Displacement: 0.26 ft³ total for both subwoofers — accounts for driver intrusions to yield real usable volume.
• Tuning frequency: 32 Hz — sets the ported response to extend lower into the bass range with controlled port air movement.
• Port area: 32 in² — port size paired with the tuning helps manage air velocity and efficiency at low frequencies.
• Baffle design: Double mounting baffle and triple flush baffle — improves mounting accuracy and reduces unwanted surface vibration.
• Internal bracing: Strategically braced everywhere with 45° braces — minimizes resonance and maintains panel rigidity during heavy bass hits.
• Compatibility: Designed for Sundown X 8" and many other high-performance 8" subwoofers — provides a reliable install path for two 8" drivers.

In a car audio build, this enclosure supports two 8" subs with a tuned, ported chamber for deep, controlled bass. The 2.00 ft³ net volume, 32 Hz tuning, and 32 in² port deliver extended low-end response while the thick MDF and extensive bracing keep the structure rigid under dynamic bass, making it a practical choice for high-performance 8" sub setups.
