Listening Room & Home Theater Size & Ratio Calculator
Quick Answer
Avoid square rooms (Length = Width) or dimensions that are whole-number multiples of your ceiling height, which stack low-frequency standing waves at the same bass frequencies. Classical acoustic room ratios—such as Louden (1 : 1.4 : 1.9), Sepmeyer (1 : 1.28 : 1.54), and the Golden Ratio (1 : 1.27 : 1.62)—spread axial modes evenly below 200 Hz.
