Russound Ratio® High Efficiency Loudspeakers are designed to provide high acoustic output with low amplifier power. This makes them perfectly suitable for use with low-power amplified keyboards and volume controls amplifying sound quality. When ordinary speakers are used with low-power amplified keyboards, they have limited output. This is because the speakers are designed to handle higher power levels than other types of amplifiers. Due to their high efficiency, Ratio speakers are louder than conventional speakers when used with powered keyboards.
