If you check your receiver settings after some sort of 'auto setup'(Audyssey for example) and it sets the subwoofer further than seems correct. Don't automatically assume it has made an error.
May 05, 2017 If one sample is 1/48,000 seconds then one sample at 48kHz is equal to 0.02 milliseconds which is equal to 0.2858 inches. Use odin to unlock phone. So, if our DSP samples at 48kHz, we can delay the signal in increments of about ¼” to compensate for one speaker being farther away than another one. So, why does this matter? There are a couple of reasons. This creates a stream of pulses at the carrier frequency. Within each period of the carrier, the duty ratio of the PWM pulse is proportional to the amplitude of the audio signal. In the example of Figure 7, the audio input and triangular wave are both centered around 0 V, so that for 0 input, the duty ratio of the output pulses is 50%.
- The propagation delay is the time taken by a signal to propagate over a unit length of the transmission line: Where: V is the signal speed in the transmission line; In vacuum or air, it equals 85.
- Use this calculator to discover the delay needed between two sets of loudspeakers. Just measure the distance between them and hit Calculate. Having the correct delay will prevent noticable echo on your sound system. Essential for live sound and conferences. This calculator uses the theory Published on Wikipedia amongst others.

Most high performance subwoofers use state-of-the-art micro processor controlled amplification these days. This tends to increase efficiency, longevity, and overall sound quality for reasons I will dive into at a later date. For now I'm going to focus on DSP enabled amplification and how this relates to the distance setting in your receiver. The correlation is fairly simple. The DSP(digital signal processing) will impart a signal delay usually measured in milliseconds. A common delay would be 5 milliseconds. The speed of sound is (roughly) one foot per millisecond. So a 5 millisecond delay will cause your receiver to set the distance setting about 5 feet more than the physical distances involved.
It may seem counter intuitive at a causal glance but the larger the distance setting, the LESS of a delay the subwoofer signal gets. Example. You have two subwoofers in the room and one is 3 feet from the seating position and the second sub is 10 feet from the seating position. The second subwoofer(10 ft away) will have its output arrive approximately 7 millisecond later(remember, one foot = one millisecond). We cannot 'speed up' the speed of sound(this isn't star trek) so we have to delay the subwoofer closer to the seating position as needed.

The distance setting is important as a correct setting will ensure a seamless 'blend' between the subwoofer and your main channels at the seating position(s).
