- Page 3 Infrasub-18 Description The INFRASUB-18 is a self powered sub woofer system employing a direct radiating 18” cone loudspeak- er in a sealed enclosure, and a 400 watt power amplifier mounted to an aluminum plate on the back of the enclosure. The circuitry also includes an INFRA dual integrator providing a flat acoustical response down to 8 Hertz, and Left, Center, and Right channel line level inputs and hi-pass filtered outputs.
- Page 4 The INFRASUB-18 Dynamic Filter threshold is not user adjustable. It has been factory set to 3 dB below the amplifier overload point. The maximum sine wave output power from the amplifier is 400 watts. With the Dynamic Filter detector engaged, the maximum sine wave output power is 200 watts.
- Page 5 How Loud at 8 Hertz ? While the INFRASUB-18 will reproduce 8 Hz, it is not audible nor does it have enough acoustical power for you to feel it. The measurements are taken at close range with sensitive instruments. To achieve a flat re- sponse, full amplifier power is used at the lowest frequencies and very little (<1 watt) in the upper frequen-...
- Page 6 The INFRASUB will send the Left, Center, and Right channel signals to the built-in hi-pass filters. The resis- tor network installed at Bag End sets the -6 dB frequency to 95 Hertz. The line level outputs of the hi-pass filters are available at the Left, Center, and Right channel RCA jacks. Send these signals back, via shielded cables, to the inputs of their corresponding power amplifiers.
