Better Music Builder (M) designing a compact line array speaker system without sacrificing audio quality, our Engineering Team introduces the R-10 & R-18 2-Way Line Array Active/Powered Speaker System.
Audio quality was not deprived off the R-10 & R-18 Line Array Speaker System with the cabinet housing size. The R-10 consists of one 10” woofer with an 2” tweeter and the R-18 consists of one 18” subwoofer. The R-18 amplified enclosure provides 1200 Watts to the 18” woofer and also provides 300 Watt RMS out to the R-10 driver.
With main inputs and microphone inputs being balanced XLR type connection, the R-18 assures the best audio quality throughout the components, providing no unwanted feedback. With the added line outputs an additional R-18 or power amplifier can receive audio signal directly form the R-18, no need for splitting cables and tangling frustrations.
Having a compact design and coming with portable flight cases, the R-10 & R-18 Line Array Speaker System can be used for a much greater list of applications with easily transportable such as at the house of worship, events, theme parks, auditoriums, schools, restaurants, malls, expositions, and many other venues. It also allows users to configure the system on a computer via software.
