"Res 4 is an excellent loudspeaker for medium scale events and installations offering exceptional sound quality.
It is a 3-way mid-high loudspeaker enclosure perfectly suited for use in medium sized applications. Dimensionally identical to the Res 5, this is a powerful and efficient mid-high enclosure which is designed to be operated as part of a four way system with addition of F-Series bass. The sonic quality of the Res 4 is exceptional. With simplified enclosure design, the Res 4 represents great value for money. Dedicated accessories also enable it to be flown and arrayed in fixed installations."
