Description
The FBT VN 4000 is a complete active PA system built around two Ventis 112A active top speakers and two Subline 118SA active subwoofers. As the largest package in the VN series, it delivers a combined 4200W RMS and provides a powerful full-range system with substantial low-frequency performance, strong mid/high clarity and a coordinated set of core accessories included. The package includes the loudspeakers, subwoofers, telescopic poles, pole carry bag and padded covers for the tops and subs.
The system uses a four-box format, pairing 12" Ventis active tops with 18" Subline active subwoofers. This gives the VN 4000 a larger and more capable system footprint than the smaller VN packages, making it suitable where a more substantial active PA solution is required. The Ventis 112A tops handle the main vocal, midrange and high-frequency output, while the Subline 118SA subwoofers provide the extended low-frequency foundation.
Each Ventis 112A top speaker features a 12" low frequency woofer and a 1" B&C high frequency compression driver in a birch plywood cabinet. The 12" format provides a strong balance of output, vocal clarity and full-range musical detail, while remaining manageable as a professional active top cabinet. Each speaker includes integrated bi-amplification, with 700W RMS for the low frequency section and 200W RMS for the high frequency section.
The Ventis 112A cabinets are built from birch plywood with a scratch-resistant finish and full-face grille. Each cabinet includes an integrated handle, M10 suspension points and a 35mm top-hat, allowing the speakers to be used above the supplied sub poles or deployed separately where required. This makes the system more flexible than a fixed-format package, as the top speakers can also be used independently for smaller setups.
The Subline 118SA subwoofers provide the low-frequency performance for the VN 4000 package. Each subwoofer uses an 18" driver powered by a 1200W RMS Class D amplifier, giving the system a much deeper and more powerful bass response than packages based around smaller 12" or 15" subs. The 18" format is well suited to users who need strong bass extension, higher output and a more complete full-range system.
A key advantage of the VN 4000 is its ability to operate as a full four-box system or be separated into smaller configurations when required. The complete setup can be used where maximum output and low-frequency extension are needed, while the individual tops and subs can also be deployed in reduced formats for smaller spaces or lower-output requirements. FBT describes the VN 4000 as a powerful full-range system that can be broken down into smaller setups when needed.
The included telescopic poles allow the Ventis 112A top speakers to be mounted above the Subline 118SA subwoofers in a conventional sub-and-top layout. This provides a clean and professional system arrangement, helping position the top speakers at a more suitable height for audience coverage. A carry bag is supplied for the poles, keeping accessories organised during storage and transport.
Padded covers are included for both the top speakers and subwoofers. This adds practical value to the package by helping protect the cabinets when the system is stored, moved or transported. For users specifying a complete system, having the correct covers and poles included helps reduce the need to source essential accessories separately.
The system is substantial but still modular in handling. Each Ventis 112A weighs 20.6kg, while each Subline 118SA weighs 44.5kg. This should be considered when planning transport, storage and setup, but the separate cabinet format keeps the system more manageable than a single large integrated PA solution.
Please look at the individual product pages for full specification on each component. Signal supplied separately.
