group delay

Hello ASR, I've heard that integrating ported subs is very difficult due to increased group delay and phase rotation compared to a sealed design. Also the ported design makes roll off sharper in order to achieve the lowest usable output for less excursion and power My question is what kind of...

Hey community, I’m resetting my strategy for deploying multiple subwoofers in my setup. Information sources include fellow members' testing (@Nuyes I measured 10 Subwoofers) and spreadsheets (@sweetchaos Subwoofer Comparison). Also using Audioholics, Buttersworth, and Erin’s to identify those...

I saw this post: https://audiosciencereview.com/forum/index.php?threads/new-ex-machina-arcturus-3-way-active-studio-monitors.47186/post-1688924 The speaker has a symmetrical step response. I hear people call it pre-ringing, but it's what has to happen if there's a low frequency cut off and the...

Hello, I have moved my system to the longwall + 15inch Subwoofer and found out that major issues in the bass region have been solved. To get some perspective here is my old thread. In this new setup, I am trying to figure out measurements such as excess group delay (GD) and minimum phase...

This have the best stereo width and depth of field from all speakers i hear. Seem because the group delay have few diffrences. there is a gap at 10 khz when it is around 15 degreee offaxis hear it get more. the group delay i have measure at 8 cm distance because only below 12 cm it give correct...

Er, actually, this thread should probably be in the psychoacoustics area. Can a mod move it? Introduction and observation: Following the fairly well received post on the relationship between group delay and spatial effects in headphones, I thought I'd start a new thread on the matter, gathering...
