phase

I'm planning adding a subwoofer to my system, but I don't want to use external DSP. Are there any guides I should follow in order to phase (/time) align the subwoofer to the mains solely by positioning and through the sub's own dsp settings (crossover, phase, etc.)? Can it be done? Thank you

During the last days I've been using a sine wave generator ("SineGen") to find peaks in my headphones and equalize them. Yesterday I noticed that this software has an option to adjust the phase of the wave, and I decided to try it out. I did several tests moving the slider with my eyes closed...

Some recent posts at gearspace made me write this post. I would like you to refer to this post from Paul Frindle (if you don't know him, look him up! He is – amongst many things – the engineer behind many iconic SSL analog mixing consoles and the legendary Oxford OXF-R3 digital mixing console)...

Today I saw a video talking about a phase shifted square wave. In that video, he show cased how a square wave and a 90 degree phase rotated square wave sounds like, which sounds the same in frequency perspective of course. But interestingly, the phase shifted square needs more dynamic range to...

Hi clever nerds :) In a continuos search for better sound, I wonder how to interpret the phase diagram in REW. Can you tell me how a correct phase should look like? This is a recording from my room from en experiment. I used the in-line RCA crossover (built in) fixed 80 Hz 12dB/oct. in my...

I did a small experiment with a little python code. I generated two pairs of signals, for each of them the first being a square signal, and the second signal with the same absolute frequency spectrum but with different phase. I did the first one in a non linear way, by adding a phase delay of...

If I'm not mistaken, single driver headphones and IEMs are known to be minimal phase systems and thus can be completely described with impulse response and distortions plot. But what about IEMs with a bunch of drivers inside with a crossover network? I don't know which order XO is usually used...

Saw this guy post on Reddit: This was for an exam and he said that the constant phase turned out to be the correct option. Any guesses why? I would have said Option 2, as the phase is lower in the bass, thus the EPDR would be closer to the raw impedance of the speaker, whereas a high phase...

I am trying to fine tune the phase for a Rhythmic L12 and a near field setup. The subwoofer is behind the listening position. Subwoofer is crossed over at 80hz via the amplifier crossover. Posted is a snapshot of the RTA using Pink PN with a sequence length of 64k, full range. Also included is...

A high phase angle (45°) results in an amplifier becoming less efficient, dissipating more heat, so it needs to draw more power to make up for that loss in wattage. If a speaker is low impedance and high phase, it really taxes the amp and many amps will not be able to draw enough power to...

I have been working on a tutorial on what phase is. This is one of those mysterious topics that is foreign to many. As I got into it, the text became longer and longer and as such, I have not been able to finish it. :) In the interim I thought I do a search to see if there are any good video...
