The self powered Quested S8R MKIII Active Monitors are ideally suited for every genre of music

Quested S8R MKIII Active Monitors (Pair)

Two class A-B amplifiers, with a linear power supply, are capable of delivering a total of 370 Watts RMS making the S8R the most powerful 2-way monitor currently available. Twin doubled flared ports in a compact reflex,enclosure help keep the dimensions to a minimum. The abundant headroom in the amplifiers and resilient drive units makes for a monitor that is ideally suited for every genre of music from Heavy Metal to the electronic music of today. A perfect choice when a full range response is required without the use of a sub-woofer. Being phase coherent with the other models in the S-Series the S8R 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.
