The VT4887A is a rugged, compact and lightweight enclosure housing two 8" woofers, four 4" midrange radiators, and two high frequency compression drivers. VERTEC’s advanced components provide extremely high power-to-weight ratio. Enclosure features foam-backed low frequency grilles, dense protective foam inserts for midrange apertures and fine steel mesh grille to protect high-frequency apertures. Speaker cones are treated with weather-resistant compounds. VERTEC arrays are rigid for maximum support strength, yet flexible in design and application. Rigging tubes made of hard-black anodized 6061-T6 Aluminum. Hinge bars made from premium-grade chromoly alloy steel, with epoxy powder coating over plated surfaces. Plated hinge pins and stainless steel quickrelease pin lanyards to resist corrosion and weather damage. The VT4887A’s suspension hardware relies on quick-release pins and end-mounted metal tubes to couple adjacent VT4887A’s together. Enclosure ships with integral front and rear hinge bar set. Protective grille cover/wheel board and soft cover ensure handy transport for rough road conditions, (purchased separately as VT4887-ACC).
