How the subwoofer placement calculator works

Room layout and subwoofer positions visualize summation and cancellation patterns, helping you find placements that reduce nulls and smooth low-frequency response at the listening position.

Key terms

• Boundary gain - extra bass when a sub is near walls or corners.
• Phase summation - in-phase sources add; out-of-phase create cancellations.
• Crawl test - moving a sub while listening finds smoother in-room bass.

Frequently asked questions
