Ideal Subwoofer Placement
What is it for? Calculates the placement that best balances room modes for one, two or four subwoofers; try it by dragging the subwoofers.
Room and Listening Information
Edge positions: Subwoofers usually cannot be placed in the middle of the room. This option limits the candidates to a perimeter strip that stays 50 cm inside the walls — it gives the best positions that are practical to implement.
Placement Map — Drag the Subwoofers
The colors show how evenly the bass will be heard at every point in the room with the subwoofers in their current positions — green = flat, balanced bass, red = dips/peaks, uneven bass.
Your goal: By dragging the subwoofers and changing their number, make your listening position and its surroundings as green as possible. The color of the rest of the room matters less — the calculation also weights your main seat 3 times more than the surrounding points.
Click and drag a subwoofer to move it (it snaps to a 25 cm grid).

Estimated Bass Response in the Listening Area (20–180 Hz)
Method and limitations: The calculation is based on a modal model that assumes a rectangular room with rigid walls; the contribution of each subwoofer is summed and evaluated over a listening area around the seat rather than a single point — this is the core approach of Welti and Devantier's multiple-subwoofer research at Harman. The model does not account for furniture, doors/windows or wall construction, so it is not a substitute for real measurement. We recommend using the positions it finds as a starting point and verifying them with software such as REW.
