Atrend E12D B Box Series 12-Inch Dual Sealed Bass Boxes

R/T 770 Enclosure Series 12-Inch Single Sealed Bass Speaker BoxThe Atrend E12D is a dual sealed 12-inch subwoofer enclosure built for those who want clean, tight bass in a compact, rugged form. Whether you're installing a system in a daily driver or upgrading a work truck, this box delivers reliable performance and long-lasting durability.

Made in the USA, Atrend sub boxes are well-known for their solid build and acoustically balanced design.

Why Choose a Sealed Box?

Sealed enclosures like the E12D are all about accuracy. While ported boxes tend to boom, sealed boxes give you that quick punch—the kind of bass you feel, not just hear. If you're running clean power and quality subs, this type of box keeps your sound tight and true. It's especially effective in smaller cabins like trucks and extended cabs where cabin gain already enhances low-end frequencies.

Recommended Uses

  • Behind-seat installations in extended cab pickups

  • Under-seat installs in SUVs or cargo vehicles

  • Paired with low to mid-range RMS 12" subwoofers (200–600W RMS per sub)

  • Excellent for sealed box lovers who want tight, responsive bass

Installation Tips

When installing the E12D in a truck or custom build, make sure you measure the available mounting depth for your subs and check for enough clearance behind the enclosure. Using a foam gasket around the sub’s mounting ring ensures an airtight seal and improves bass response. Add polyfill to each chamber if you’re looking for slightly deeper bass without increasing box size.

Summary

The Atrend E12D is a great choice for serious audio lovers who need solid bass in tight spaces. With dual sealed chambers, sturdy build, and clean performance, it’s a plug-and-play solution that delivers. Whether you're an audiophile or a daily driver looking for more low-end punch, this enclosure is worth the upgrade.
