Quested S8R

2-Way Active Monitor

Description

The S8R is the largest of the S Series monitors. With an 8” low frequency transducer coupled to a double
flared front loaded port design means reduced turbulence. This design also allows for easy placement of
the S8R in compact spaces. The on board amplification delivers 370W RMS split with 220W RMS to the
8” LF and 150W RMS to the silk dome tweeter. Attenuation to the input sensitivity along with low and
high frequency is available on the rear panel. The operating range is 53Hz – 20kHz with a +- 2db
tolerance and a -6dB cut off down to 41Hz. The S8R is suitable for use without a sub for the majority of
monitoring applications. The S8R can also be partnered with the SB10R should further base extension be
required down to 27 Hz.
