Adjusting the controls

There are two main methods for adjusting the level, crossover frequency and phase of the Earthquake MiniMe to match a system.

?Method One: Typical: Listening and making adjustments to suit your taste.

?Method Two: Laboratory: By measuring the output and adjusting for a flat frequency response.

Satisfactory results can be achieved if you make the adjustments based on simply listening. This is Earthquake's preferred method as it allows the system to be voiced based on what sounds the best, whereas laboratory-flat frequency response can often be clinical and less than exciting.

The following procedure is for those who prefer a more methodical and scientific approach.

You will need a test CD with low-frequency warble tones, and a sound pressure-level meter.

Step #1

Disconnect the subwoofer and run the main speaker with a tone in its passband (80-100Hz). Measure the level.

Step #2

Disconnect the main speaker and reconnect the subwoofer. Set the subwoofer to its highest crossover frequency. Set the level control of the subwoofer to give the same sound pressure level with the same tone you used in Step #1.

Step #3

With both the subwoofer and the main speaker connected, measure the level of the tones at the available frequencies. Because the crossover is set too high, you will have a peaked response. Adjust the crossover control to get the smoothest response.

Step #4

Use the phase control to make the response even smoother. It has its biggest effect at the crossover frequency. You can iterate between the crossover and the phases controls. Keep your hands off the level control! It was set correctly in Step #2.

Step #5

Listen to the subwoofer. Resist all temptation to turn up the level control. Play something with really deep bass to confirm that your subwoofer is working.
