Quested S8R 2-Way Active Monitor

The Quested S8R Two-Way Active Studio Monitor is a powerful yet compact studio monitor system that works just as well in larger control/mix rooms as it does in more confined spaces. The S8R does this with a double flared front port system, reducing turbulence.

With 370 Watts RMS total power via it's onboard amplifier, the Quested S8R provides an impressive operating frequency range of 43Hz – 23kHz offering impressive bass extension while retaining a neutral frequency palette.

The Quested S8R, like all Quested monitors, is built in the UK and comes with the company's 5-year Warranty. Get in touch to arrange a demo.

Product Description

The Quested S8R is the largest of the S Series monitors. Its 8” low frequency transducer coupled to a double flared front loaded port design means reduced turbulence, making it ideal for placement in confined spaces. The on-board amplifier provides 370W RMS in total – 220W RMS to the LF driver and 150W RMS to the silk dome tweeter.

Attenuation control for input sensitivity and individual LF and HF fixed level control exists on the rear panel.

With an operating range from 43Hz – 20kHz (+/- 2dB) the S8R perfect for the vast majority of monitoring applications. If low frequency extension is required the S8R can be partnered with the SB10R sub cabinet, taking the system down to 27 Hz.
