Hello,
I would like to introduce DIY community to new solution which is not so new for professionals. It was at the AES convention in October 2006 when professionals were introduced to it. And now it is widely used for studio monitor tuning to get the most accurate reference possible which allows recording producers and sound engineers to do their job two times faster as before.
Many years ago we had just two „knobs” - LF HF to adjust some device’s sound to our preference – turn knob, listen to result. Turn again; listen again ... and so on.
Then, when electronics became more advanced, we had 10 knobs (1 octave EQ) and we had more space for our creativity – turn and listen.
Then, when electronics became much more advanced, we had 31 knobs (one third octave EQ) and some kind of analyzer with about 31 bands usually. Now are able to see analyzer results, not just listen to them. And we now see, turn, listen... and so on... And we „know” that not every dip that we see on curve is supposed to be equalized.
Everyone who has tried to do such a job knows that it is infinite job ...
Another story is with „power” domain measurements introduced to world in far 2004-2006.
With power domain measurement curves you don’t need to decide which of the dips are qualified to „do not touch” and which are supposed to be corrected. Everything on curve is valid.
This tends to create CAD of EQ – Computer Aided Design of EQ.
We can get highly trustable curve of Sound Power Frequency Response or Sound Power Density Response (for closed environments as car interior).

And by use of CAD of EQ (APL Workshop software) can create EQ filter based on SPFR – SPDR measurement: Acoustic Power Lab :: SPFR

Now tuning process is – measurement, equalizer design, listen to result, add some preference (parametric EQ) listen to result and that is it.
And you can start from such result:

You have full freedom to decide how much to follow measured curve and how much to introduce your own.
But CAD will free you from routine job to recreate curve by use of some parametric EQ and it will free you from decision “do” or „do not touch” and allow you to use your creativity to find your own sound.
In such way APL with a help of Sergey received two gold’s in EMMA 2013 European championship’s „heaviest” classes: http://aplaudio.com/conc2/awards/
Costs: APL Workshop software -320 euros, and APL1 FIR equalizer unit- 400 euro.

If you are representing tuning studio you just need one copy of software to install and setup any number of APL1 units.
There is APL EP1 VST plugin available for „Car PC” users for 150 euros.
APL Workshop software demo and APL EP1 VST plugin is available to take a look over APL equalization solution without hardware and for free.
Alexander Martyanov ((his nick is „martyanov” here and he is two times EMMA European champion Sergey’s engineer)) has 4 year experience of APL installations into SQ competitor cars. His build log is available here: http://www.diymobileaudio.com/forum...-gen-honda-crx-uncompromising-sq-install.html
