The VT4887 is a compact, lightweight enclosure housing two 8” woofers, four 4” midrange radiators, and two high frequency compression drivers. Advanced components provide the highest power-to-weight ratio of any speaker system in its class.

Enclosure features foam-backed low fre- quency grilles, dense protective foam inserts for midrange apertures, and a fine steel mesh grille to protect high-frequency apertures. Speaker cones are treated with weather-resistant compounds. Rigging tubes made of hard-black anodized 6061-T6 Aluminum. Hinge bars made from premi- um-grade chromoly alloy steel, with epoxy powder coating over zinc-plated surfaces. Cadmium-plated hinge pins and stainless steel quick-release pin lanyards to resist corrosion and weather damage.
VERTEC arrays are rigid for maximum sup- port strength, yet flexible in design and application. The VT4887’s suspension hard- ware relies on quick-release pins and end- mounted metal tubes to couple adjacent VT4887’s together. Enclosure ships with integral front and rear hinge bar set. Protective grille cover/wheel board and soft cover to ensure handy transport for rough road conditions, purchased separately as VT4887-ACC.
