Powerful 18″ Active Subwoofer – 2500 W RMS, 143 d B SPL

VHA 118.2SA Processed Bass reflex Active Subwoofer – 1×18″ – 2500WrmsThe ground-stacked VHA118.2SA is an exceptionally powerful and versatile subwoofer that sets a new standard for SPL to size ratio. Comprising a single 18″ long excursion B & C woofer, the birch plywood, bass reflex sub, features a 2,500W Class-D amplifier module with 143dB SPL and offers a selection of six entirely rewritten preset algorithms. Processed Active Subwoofer – 2500w RMS – 140dB SPLFor larger spaces, the ground-stacked VHA118SA is an exceptionally powerful and versatile subwoofer that sets a new standard for SPL to size ratio. Comprising a single 18” B&C woofer, the birch plywood, bass reflex sub again deploys a laminar air-flow for refined performance, while its 2,500W Class-D amplifier module offers a selection of six entirely rewritten preset algorithms.The design of the VHA118SA has produced a unique low-end module that is capable of generating extremely high levels of SPL for prolonged periods. Using BEM finite element simulations, FBT has optimised the woofer’s load volume, while careful study of the grille and the assembly’s protective fabric have minimised acoustic impedance for a net improvement in performance compared to previous models. The addition of the VHA118SA extends the overall system frequency response to 30Hz, while the sub can support fully ground-stacked configurations courtesy of special integrated mounting hardware.
