S8R

S8R

S8R by Quested Monitors

The S8R is a self-powered, 2-way active monitor.

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.
