mijostyn i have anything against measurement....In electronic design they are the ground on which some standards can be built upon, and the are indications for the designer...
In acoustic i dont need them at all ....
My acoustic settings are perfect for my ears.... It takes a lot of time almost 3 months but it has been only fun.... Each few days i improved.... Now i had some music test file i know very well, each one of them with an instrument, orchestra, or voices i know well....
When all sound natural the puzzles is in placed solved....
Is your puzzle solved at all audible level for all timbre of any instrument with holographic 3-D in classical and well recorded jazz albums ? When the recording make it possible with voice or instrument coming on the side or the back?
Is your speakers better than 7 headphones on all count?
The mechanical equalizer is so poweerful that my "not ideal" position for the speakers is compensated for so well that this does not disturb me....
A 13 feet square room is not ideal one with one of the speaker in a corner..... Try to equalize that....
I use pressure distrubution zones and marked out pressure zones coming from tweeter and bass driver to pilot the direct waves with the reflections for each ear....
You cannot do that.....modification of the speakers response cannot be mechanical modifications of the room response....I modify the room for the speakers NOT the speakers for the room only .... And i modify also the speakers for the room but i dont use a narrow frequency response but a relatively large one.....
My solution is not esthetical and not for a living room anyway...
Certainly someone very crafty can design this to be a modern scupture grid but i am not crafty just imaginative...
Anyway i apologize for my rant and i wish you the best....
