P= Passive Radiator A= Active Driver

Fact: Subwoofers reproduce frequencies with wavelengths that are long in relation to the dimensions of most living rooms. Standing waves will boost or cancel various frequencies due to the interaction with the room boundaries. Moving a subwoofer in a room will change what you hear in the listening position a lot.

For maximum bass reinforcement, the MiniMe subwoofer system should be placed in the corner of your living room, with the subwoofers facing the wall. This creates acoustical coupling with the walls, which in turn leads to a 9 decibels of boost in the overall response of the MiniMe. Keep a 3" clearance between the subwoofer and the walls.

Fine tuning the MiniMe requires adjustments to the crossover point, volume control and the phase switch. These controls are located on the side of the enclosure. For ease of tuning we recommend that you turn the MiniMe around to expose the controls, and place it in position (corner). Set your stereo system to a moderate listening level and adjust the MiniMe accordingly. The MiniMe is equipped with a 24 dB / Oct. Low pass filter designed to eliminate vocals from entering the system. When tweaking, gradually reduce the crossover point setting to eliminate vocals from seeping into the amplifier.

Your Earthquake MiniMe is designed to be placed in a corner and this will produce optimum performance. Experiment with at least two corners then decide which is the best.

#1 is very good positioning.

#2 is also excellent but may shake the back wall too much and cause things on or along the walls to rattle too much. If this occurs, use the #3 position.

#3 Move the woofer approximately three feet away from the right wall and place it along the back wall as shown. This will substantially reduce the rattling of the back wall

and will still pressurize the room with lots of bass.

Although low frequencies are non directional, factors such as room reflections, standing waves, resonance, and absorption strongly affect your subwoofer's performance.

Also position the control panel so that it is not touching anything and can receive good ventilation.

Using Two Subwoofers

If you choose the use two woofers, the sound output will double (an increase of 5dB). Locate the woofers with one in each corner and experiment with the location and phase control to achieve the best bass response.

Always drive each woofer through the Left/Mon input even though you are driving one woofer on a right channel drive and the other with a left channel drive. If your pre-amplifier has a single dub/LFE output, use a 'Y' cable to split it into two outputs.

Remember to keep it at least two or three feet away from any TV screen, computer, VCR or magnetic tapes and discs. This will reduce the chance of the magnetic field upsetting the TV screen or erasing your magnetic media.
