Configuring your system to work with your
X-Ref 10 DSP Powered Subwoofer
No special configuration of your system is required for it to work perfectly with the
Emotiva X-Ref 10 DSP Powered Subwoofer. Most bass management systems will cross
over between the main or satellite speakers and the subwoofer at between 80 Hz and
120 Hz (80 Hz is the THX™ standard crossover point). The X-Ref 10 DSP Powered
Subwoofer is flat to above 200 Hz, and so will work perfectly with any crossover setting
your bass management system chooses to implement.
If you are configuring a preamplifier with bass management (like our Emotiva
USP-1) to work with satellite speakers, then choose the crossover point recommended
by the manufacturer of your speakers (this is often 80 Hz for “satellite” speakers). If
you are using full range speakers, then experiment with crossover points at or below
80 Hz until you achieve a pleasing result (the goal is to choose a point at or above the
frequency at which your main speakers sound strained or start to roll off in frequency
response).
If you are using a preamplifier without bass management, and you have full range
main speakers, then you will be using the X-Over (crossover) configuration on the
X-Ref 10 to configure the X-Ref to cut off at or about the frequency where your main
speakers stop producing sufficient bass, and the Volume configuration on the X-Ref to
match its level to that of your main speakers so the overall sound is continuous and
smooth - with no sudden jumps in output level. Simply try different frequencies until
you achieve a pleasing result.
