TREO Engineering is proud to offer a pre-loaded enclosure that is specifically made for TREO TSi12.8 subwoofers. The TREO TSiBox12-8 is a ported enclosure pre-loaded with two TREO TSi12.8 subwoofers. Installation is a snap because the woofers are wired in parallel inside the box so there is only one set of speaker connections on the outside of the box.

There is no sacrifice in sound quality or output thanks the TSiBox12-4's high-efficiency ported design. The pair of polished aluminum three inch ports are flared on the end to reign victorious in the battle against port noise. The premium-grade black carpeting matches the classic cosmetics of TREO subwoofers.
