Location The suggestions below will typically result in outstanding performance. However, although low frequencies are non-directional, factors such as room reflections, standing waves, resonance and absorption will strongly affect your subwoofer’s performance. Since your Sunfire subwoofer is designed to be professionally installed into your wall, engineering services from your authorized Sunfire dealer and/or outside acoustical resources should be considered to ensure optimum performance.
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 200 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.
Installation Read and follow all instructions and all important safety instructions in the HRSIW8 amplifier manual. Here follows a summary of the amplifier installation notes: • • • The amplifier may be rack mounted using the supplied rack ears. It will fit into a standard 1U, 19 inch rack space. Allow a minimum of 1 free rack space above and below for ventilation. This is very important. The amplifier may also be placed on a shelf, supported on its feet.
System Configuration HRSIW8 Amplifier HRSIW8AMP Connect balanced or unbalanced inputs to the SUB/LFE line-level output of your home theater preamplifier or receiver.
Subwoofer Installation Read the details on page 7 to help determine the best position for your subwoofer in the room. The subwoofer can be wall mounted vertically, centered between vertical wall studs. This is the recommended (and easiest) orientation to install. Horizontal mounting into existing construction will most likely mean cutting a vertical stud. This installation should be done by an experienced and qualified carpenter, to prevent weakening the wall structure.
Wiring The HRSIW8 amplifier has two binding posts for connection to the HRSIW8 subwoofer. 1. Install the speaker wires following all local codes for low voltage electrical wiring installation. Use class 2 wiring, and 12 gauge is recommended, 16 gauge is the minimum. 2. Follow common low voltage practices like avoiding high voltage electrical wiring, or if this is not possible, try crossing them perpendicularly. This will reduce the chance of picking up hum or other interference. 3.
2. Screw in the six clamp screws. As the screw turns clockwise, a clamp rotates out and presses onto the back of the sheetrock to hold the subwoofer firmly in place. Tighten the clamps so they are snug, but do not overtighten, as they could damage the sheetrock. Final steps 1. Add the grille to cover and protect the woofers. 2. The grill can be painted if desired, and this best done when it is not attached to the subwoofer. 3. Enjoy your new subwoofer.
