Why Choose This Product?

This version is worth considering when a single 12-inch subwoofer calls for the listed airspace and 35 Hz tuning. Its 30.00 x 16.50 x 15.88-inch external dimensions offer a different layout from the model-specific Elite XXL enclosure, so check both fit and acoustic requirements.

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.
  • 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 1 compatible 12-inch subwoofer is 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 12-inch size label alone is not enough to establish fit.

Which direction do the subwoofers and port face?

The driver mounting position faces upward and the port faces the back. Check clearance above the subwoofer and around the port in the planned installation.
