Is DEQX a game changer?

Bruce previously sent me his files and Larry windowed at 24ms and 98% smoothing. My own outdoor measurements are windowed at 26ms & 0% smoothing because measuring 'anechoically', the plots are clear and have almost no reflections or impulses other than the speaker itself - it's an almost flat line until a clear and tiny reflection at 26.2ms which repeats every 3ms until fading away at 36ms

However the windowing I quote is based on reflections made by Bruces' setup and will be different for yours. To be safe, I would suggest you try to look for a clear smoothish area after the main impulse and before the first obvious reflection. However, that may be difficult with a somewhat confused indoor measurement

Drewan ... in your opinion, did Larry "time align" tame my beasts pretty well? Ditto room correction?? What is the significance of "windowing at 24 ms"?? What is better ... a long or short ms time frame? Or is the question a non sequitur??

@Al ... just an fyi. Maybe Drewan can weigh in a little, but my general recollection is that my room wreaked havoc up to 500 Hz. Plus, my speakers weren't all that flat north of 500 Hz.

Another point. Larry basically cut the S8's woofers out of the picture. He used my subwoofer to do the heavy lifting below 120 Hz.

Part of the problem related to the room for sure. But also, the mid and tweeter drivers are wired in reverse polarity as compared to the woofers. So he reversed the overall polarity of the signal and matched the time alignment of the mid and tweeter drivers with the subwoofer. The S8's woofers are only working from 120 Hz to about 230 Hz. The sub is picking up the load from 13 Hz to 120 Hz.

That's why I described the DEQX as turning my signal into a pretzel in order to tame my system.

Drewan, if you have my e mail address, send me a PM and I will send you the latest files which reflect Larry's most recent "fine tuning" adjustments that he did on December 4, 2014. Same offer to you Al.

@Al ... just a final thought. You will soon learn how the designer of your speakers wired the cross over when you do the signal impulse test. As I mentioned, Paradigm reversed the polarity of the mid and tweeter drivers as compared to the woofer to achieve phase coherence at the cross over points.

I'm sure Richard Vandersteen would cut his hands off before doing such a thing.

Sounds like a good idea to use acoustical absorbing devices to reduce the magnitude of reflected sound that would reach the calibration microphone otherwise. Would seem to be a positive step towards reducing effects of room acoustics.
