We called it Eris because it’s been designed from the ground up to be part of the family; it compliments the voicing and frequency response of the modern Eris classics.

Of course, they’ll play nice with other monitors, too, but if you’ve got a pair of Eris in your home or studio already, the Eris Sub8 is the single best subwoofer you can get to put a little boom in your room.
