Group Delay Correction?

pandaemonium9 · 29th December 2007, 08:55 PM

Can anyone point me to info or a schematic for group delay correction? I don't have a bad problem with my sub, but, hey, it's a hobby, and I want to play with my sub! I'm playing with a RSS315HF-4 and a Bash 300 amp (nice for modifications!), in a vented box. Maybe I should use something like low and high pass filters and digital delays, and then remix them?

group delay correction? Try a "Linkwitz transform".

Do you mean that you want to make an active circuit to adjust the phase response of your subwoofer at the higher end of its range to get it in phase with the satellites?
