The ELEMENTS E 115 Sub D is a new, high-performance system subwoofer that uses state-of-the-art controlling and amping technologies to take the audio performance and adaptability of the successful Elements series to a whole new level. The 15" high-power woofer is driven by a 1500-watt power amplifier, whilst a second 900-watt power amplifier is available for driving up to three E 835 mid/high units. In addition to the remarkable performance, the new network-compatible subwoofer has the same elegance and visual appeal as the rest of the ELEMENTS series, which is a real hit among discerning musicians, rental companies, DJs, installers, and presenters at corporate events.
