No one can hear a 1 millisecond delay from a subwoofer.There have been studies showing a 5 millisecond delay (subwoofer five feet further from ears than main speakers) is the minimum audible delay. Some experts suggest no more than three foot differences (3 ms) to be safe.
No one has ever presented any evidence that a one millisecond bass delay is audible by even one listener.
But ... most people CAN hear a room bass resonance that stays audible for roughly 200 milliseconds AFTER the sound from the subwoofer (or full-range speaker0 stops (-30dB attenuation assumed to be "inaudibility").
So if a one second delay bothers you, just move the subwoofer one foot closer to your ears to eliminate it!
