The VTX F18S 18" High Power Subwoofer from JBL is a compact, high power, cardioid-arrayable single subwoofer designed for use with the VTX F12 and F15 Loudspeaker. For small to medium format front-of-house applications, single or multiple VTX F18S Enclosures can be used with VTX F12 or F15 Enclosures in subwoofer / satellite mode. The VTX F18S Subwoofer is also suitable for drum, DJ, or side fill monitoring since it has been strategically dimensioned to physically integrate with either VTX F12 or F15 Enclosures.
Specifically designed for demanding tour sound applications, the VTX F18S Subwoofer features the 2269H Differential Drive 18" transducer which provides high-output yet low-frequency performance. For flight case conditioning, the subwoofer depth is equivalent to the depth of two VTX F15 Enclosures, allowing a single flight case to be used for both models with dimensions that are truck pack-friendly.
The basic cardioid building block consists of two enclosures front-firing to one enclosure rear-firing and with appropriate processing up to 20dB of rear rejection is obtained, significantly reducing low frequency spill back onto the stage for the performing artist. Four convenient handles are provided and multiple M10 mount points (4 per side, 4 top and bottom) allowing for installation flexibility for either portable or fixed installation. For drum monitoring, M10 mount points can be used with supplied attachment plates that allow VTX F12 or F15 enclosures to be physically secured to the F18S (F12 horizontal with F18S vertical or F15 horizontal with F18S horizontal).
