For instructions on how to use this calculator, please watch the below video.

If you do not quite understand the concept of Time Alignment make sure to start the video at the beginning for a concise explanation.

Speaker Measurements

Please input measured distances from each speaker to the listening position in inches (to one decimal point), below. The more precise the measurement the more accurate the results will be. If you enter values for the crossovers, then that method will be used for the TA calcs. Leave them blank and the more 'traditional' method will be used.

Will this be a 2-way or 3-way?

3-Way 2-Way

Is this a Pioneer setup?

No Yes

Moving The Stage

This is to be done only after you feel your focus is correct, but you simply want to shift the stage.

For example, you've tuned the EQ and set levels and delay. However, if you still feel the stage is skewed so that the center is toward the right some distance. You enter the distance you wish to shift the stage and the calculations below will give you approximate numbers so that your time alignment isn't off from your levels, otherwise causing you to lose the focus.

Move stage inches

Adjust the following:

Left time delay ms
Right time delay ms
Left level by db
Right level by db
