The S8R MkIII from Quested is a two-way active near-/mid-field reference monitor that features two class A-B amplifiers with a linear power supply, capable of delivering a total of 370W RMS. This monitor has a twin doubled-flared port in a compact reflex enclosure that helps save space. The large headroom in the amplifier and resilient drive units make the monitor suitable for multiple genres of music.
The S8R is an ideal choice when a full range response is required without the use of a subwoofer. Being phase coherent with other models in the S-Series, it can be used in combination with them in multi-channel systems. Typical applications include full-range monitors in medium-sized control rooms, near-/mid-field monitoring in larger rooms, programming rooms, and components in multi-channel systems.
