The HRTF panner uses significant memory for the responses and requires a fair amount of processing to implement. For low-end mobile devices, this can be an issue. Since the default panner model is HRTF, the creation of the panner can cause the responses to be loaded. The default has been changed to equalpower, which doesn't consume significant memory and is much less intensive in processing power.
