125-130hz boost problem

[Nyal Mellor]

Nyal,

THANK YOU...100% support John's updates. I had actually blown off the REW update notice putting it in the "I'll do that soon enough" category. I will now update right away.

Ironically, I just last week used the Group Delay to determine secondary space cause/effect of a gentleman's room: having data from each speaker individually and both, the Group Delay shows clearly these issues. The relationship of the Group Delay from V.4 had me thinking of how to properly apply EQ. John is a leader.

Very exciting.

Yes it is exciting. Giving the new algorithms a good work out is also still in my 'to do' as well Jeff! Anything to make setting EQ up (where it is required) a quicker and better process than the multifaceted process of manually looking at FR, time decay, adjust, look at FR, time decay, adjust....you know how it goes

This article is also very interesting reading. It's been in my bookmarks for about 5 years. I love the story told within it. http://digitalcontentproducer.com/mag/avinstall_art_equalization/

Thanks Nyal for the link. Great lessons from the foundational "heavies".

While offering resources, Phillip Newell's Loudspeakers book covers all of this topic in incredible detail and forward thinking knowledge. He proposed a LF measuring technique similar to STI used in large room speech intell study where you are graphing the deviation of the response against the input (source signal). This, he counters, tells what the freq response doesn't...how the details and transients are being presented at the measuring position. It is a fantastic book for most anyone here at WBF.
