6 Considerations
• Two smaller subwoofers are better than one larger one. There is less localization and more uniform bass sound with two subwoofers.
• Do Not place the subwoofer too close to the listening are. It will feel like you are being pounded with a pillow.
• Do not place the subwoofer in the rear of the room unless you are installing more then two subs. The first two need to be in the front plane.
• The front firing, front ported FLSUB makes the perfect unit for custom built-in cabinet. Insure proper ventilating with a small fan.
• Do not obstruct the sub speaker or the slotted port. To produce bass a great deal of air has to be moved.
• Make sure the front edge of the sub is even with the front edge of your cabinet. If not a tunnel sound will occur.
• Do Not use harsh cleaners on the FLSUB cabinet. Use mild soapy water. A wax like Pledge will renew the shine. Check the label!
• As a minimum use a quality 2-22S shielded wire when prewiring in the wall. Avoid running next to any AC power lines.
• Connect the shield on only one end to prevent ground loops that can cause hum. Connecting the shield on amplifier end is preferred.
• When pre-locating the subwoofer make sure you have a 110VAC or 230VAC outlet next to the jack. The FLSUB requires AC power.
• Every surround sound home theater should have at least one powered subwoofer. Two is an improvement.
• Many receivers must have the Sub Out signal enabled. This is accomplished in the receiver menu. Check receiver instructions.
• Install an ILS120 Surge Protector or equivalent surge protection.
• Some homes have uneven ground potentials that could cause hum in the amp. Try a two prong ground isolator to solve this problem.
