Center location Installing the subwoofer closer to the center of the front wall will still provide adequate bass, but will tend to be less “heavy” and somewhat tighter. This is ideally suited for: • For rooms smaller than 00 square feet • Dedicated music listening rooms. Center location for one subwoofer Using Two Subwoofers If you wish to use two subwoofers, the sound output will double. Each subwoofer will need its own dedicated Sunfire HRSIW8 amplifier. Locating the subwoofers on the front wall, with one towards each corner will provide more flexibility in crossover points, without causing localization that can happen with subwoofers located on side and rear walls. Sunfire preamplifiers and receivers feature multiple subwoofer outputs for these applications. If your preamplifier has a single sub/ LFE output, use a Y cable to split it into two outputs, one for each amplifier. Corner location for two subwoofers User's Manual... -
