Audible stereo-bass spatial effects occur mainly above 80 Hz

Evidence

The model assumes devices or channels that are tuned to particular interaural delays. These devices, which exist only for frequencies below 1500 Hz, are assumed to be arrays of channels each tuned to a different characteristic interaural delay. Each channel then acts as an interaural delay filter. It transmits whatever signal arrives at its characteristic delay without attenuation, but attenuates more and more those signals that arrive with delays that are increasingly different from the characteristic delay of the channel. — Professor Dr.-Ing.
