VTX S25 is a compact, high-output, cardioid arrayable line array subwoofer element designed to provide high impact, high quality sound reinforcement of sub-low frequencies for a wide variety of live music and A/V support applications. Patented Differential Drive® low frequency transducer technology and BSS® Audio OmniDrive HD V5 processing provide uncompromised sound quality while simplified suspension hardware and JBL HiQnet Performance Manager software provide efficient transport, fast setup and precise configuration. Whether ground-stacked, suspended beside or behind V20 or V25 arrays, or employed in hybrid arrays with VTX V20, the VTX S25 can be deployed in either front-firing or cardioid mode. For cardioid configurations (multiples of 3 S25 enclosures with 2 front-firing S25 : 1 rearfiring S25) 15-25 dB broadband SPL rejection can be obtained behind the array.
