I have been using the minidsp 2x4 with dual subwoofers and love it. However, I have recently noticed something awry.

When I recently evaluated my setup, I started thinking about the subwoofer distances, ie; the closest subwoofer should have the most delay, right?

Well, when I opened the plugin and double checked the distances vs delay, the closest subwoofer has the least delay and the furthest subwoofer has the most delay. I set them up according to the manual by measuring (with a laser) and inputting the delay according to the distance. Am I correct by thinking something isn't right? When I add distance to a subwoofer, it adds delay. Shouldn't it be shortening the delay as I add distance?

Am I being a little too straightforward here? Maybe I should be measuring, calculating and inputting the delay then ignoring the distance that it shows in the plugin once I calculated it?

I have dual subwoofers in a 5.2 setup . The subwoofers are not equidistant from the MLP.

Correct, the closest sub should have the most delay. Sounds like it would be good to review your distance and delay calculations. Info below is a summary of what AustinJerry posted in a previous post in this forum...
  1. Measure physical distance to each sub and write em all down, in inches
  2. Using the distance to your furthest sub as your reference point, subtract each sub's distance to get your "delta" or "difference" distance.
  3. Calculate your delay by dividing your "delta"by the speed of sound, then multiply that by 1000. So if your "delta" is 36 inches, it would be 36 / 13,512 * 1000 = 2.6 milliseconds
  4. Wash rinse and repeat for each sub, then enter these values into the miniDSP 2x4 plugin
