The JBL SRX918S VT Vertical Transporter is a professional, heavy-duty dolly engineered to streamline live event logistics and maximize efficiency for touring crews, mobile production teams, and equipment rental houses. This rugged platform is designed to securely hold and transport up to three JBL SRX918S or SRX918SF subwoofer cabinets in a single vertical stack. With a compact footprint measuring exactly 30 inches by 30 inches, the cart conforms perfectly to standard truck-pack dimensions, enabling production crews to maximize cargo volume, simplify loading configurations, and drastically reduce overall setup and load-out times at the venue.Constructed from premium 18 mm outdoor-grade Baltic birch plywood and sealed with a highly durable, scuff-resistant DuraFlex finish, the transporter is built to withstand the rigorous demands of professional touring. The cart features integrated stacking guides that align the subwoofers flawlessly, allowing technicians to pre-configure their stacks in either standard front-firing or cardioid arrays directly on the cart before wheeling them into place. Equipped with four heavy-duty, smooth-rolling casters and an included 50 mm wide black ratchet strap to securely anchor the speaker stack, this transport solution guarantees safe, stable mobility over rough venue terrain.
