Why Choose This Product?
Choose this layout when an upward-facing 15-inch driver and rear-facing port suit your installation plan. The 34.00 x 14.00 x 22.00-inch footprint, 35 Hz tuning and 52.00 in² port area provide clear comparison points for your chosen driver.
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 gives 0.15–0.25 ft³ as a typical 15-inch driver displacement range. Your selected subwoofer may differ, so verify its 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 1 compatible 15-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 15-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.
