The sealed design prioritizes sound quality and space efficiency, making it an excellent solution for daily drivers, overlanding builds, work vans, and custom audio upgrades where clean integration is a priority.

    Designed for flexible installation, the S2-SB8-DT includes dual terminal inputs for easier amplifier matching and wiring configurations. Included mounting hardware supports convenient under-seat installation, including select Mercedes Sprinter Van applications, and it is also compatible with the optional KTX-EBKT Universal Mounting Bracket for up-firing and side-firing configurations.
