Product Overview
The Tru Spec dual 10-inch sub-up, port-back enclosure provides 2.50 ft³ of stated total net airspace for a compatible pair of drivers. Its double flush baffle and 35 Hz tuning distinguish it as a specific enclosure configuration rather than a universal fit for every 10-inch subwoofer.
This is an empty enclosure only. No subwoofer is included.

Why Choose This Product?
Consider this version when your two-driver plan calls for the stated 1.25 ft³ per subwoofer and the upward-facing layout suits your vehicle. The 30.00 x 16.50 x 15.88-inch dimensions differ from the Sundown SA-specific dual 10-inch model.
Installation & Compatibility Notes
- The quoted net volume uses the supplier's 0.24 ft³ total driver-displacement allowance. A different driver displacement changes the final available airspace.
- The supplier uses approximately 0.12 ft³ per 10-inch driver as its reference for this two-driver configuration. Verify your selected pair's actual displacement.
- Measure the intended vehicle space and its access opening. Check basket and motor clearance, mounting depth, terminals and cone clearance against the actual driver. No vehicle-specific fitment is claimed.
- A maximum mounting-depth measurement is not provided in the supplier description. Confirm clearance for your exact subwoofer before purchase.
- Leave the port opening unobstructed and confirm the driver manufacturer's recommended ported volume and tuning. Secure the enclosure appropriately for the vehicle installation.
Frequently Asked Questions
Are subwoofers included?
No. This listing is for an empty ported enclosure only. The 2 compatible 10-inch subwoofers are selected and purchased separately.
Does matching the nominal subwoofer size guarantee compatibility?
No. Confirm the exact model, cutout, mounting depth, basket clearance, displacement and recommended enclosure volume. A 10-inch size label alone is not enough to establish fit.
Which direction do the subwoofers and port face?
The driver mounting positions face upward and the port faces the back. Check clearance above the subwoofers and around the port in the planned installation.
