Designing a compact line array speaker system without sacrificing audio quality, Better Music Builder Engineering Team introduces the R4/R8 Line Array Speaker System.

Having a compact design, the R4/R8 Line Array Speaker System can be used for a much greater list of applications 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.

Audio quality was not deprived off the R4/R8 Line Array Speaker System with the cabinet housing size. The R4 Drivers are four 4” with an included ribbon and the R8 consists of two 8” subwoofers. The R8 amplified enclosure provides 300 Watts RMS to the 8” woofer and also provides 4 x 75 Watt RMS out to the R4 drivers.

The R4/R8 Line Array Speaker System features one of the best complete protection packages Better Music Builder has ever introduced with built-in cooling fan, overload protection, short circuit protection and temperature protection along with an overload indication LED display.
