Just finished the system integration last night, into the wee hours , mighty impressive

I’ll be sharing soon how this is done and how I believe the best approach to EQ and full system integration should be done, amazing stuff !

Let’s get to the methodology behind, stats, quantitative measurements, analysis and actual listening

I haven’t done the actual listening, but quick listening, it’s promising. The numbers don’t lie

I will be interested to know more about your approach and measurements in EQ.

I've got my own way using REW for time alignment between mains and subs, but I'm always looking for better methods if there are.

I have to say that there are 2 parts of any audio system EQ. Basic start point (to being with) and then followed by calibration to preference(pepper and salt to your taste).

Hi Jag, this methodology that I use now is really good, I’m having 8 subs, and you will see how they all sum nicely. The key take away with this method is that the mains sum up with subs, blending at XO, it’s so much easier vs the distance tweak method I was using in the past.

The other notable benefits were impulse all aligned, then we have very less seat to seat variation, all the seats are equally good. Then comes a good decay rate, which I will share as well with the spectrogram, mighty impressive for 8 subs in a living room. These all automatically translates to good phase coherence as well.

Harmonic Distortion numbers were very very impressive too, <2% at 92db below down to 10hz...

Let me just jump in quickly here to prevent the topic from going OOT.

@Roni - You may want to start a separate thread or continue with your post on the Lyngdorf thread to expand your sharing/discussions on the audio calibration :)

Sure sure, once I’ve compiled the details, will share in that thread instead
