How competitive are you with your system?

@mihorn @carlos269

I decided that in fact the upper midrange was a bit brash.  Rather than being in the upper end of the 10", it was in my tuning of the Heil.

I have developed a method of tuning the Heil AMT quite unlike any other yielding a totally different response.

I use a "reflector" behind the diaphragm that sends the rear wave forward meeting the front wave.  The result is that, using mechanical means, I can produce a fairly flat response from ~3,500 up past audibility.  The response drops like a rock below this, even if there were no crossover.  This is why the system sounds so detailed and open.

The distance of the reflector from the diaphragm controls how much signal is added from ~3,500Hz - >6KHz where the Heil would normally still be "coming in".

As the reflector is moved closer, you pick up more in this area, the slope below to the woofer is increased, and the peak in the 10KHz area is reduced.  We are talking on the order of >3 dB and the differences are easily notable.

Anyway, is was simply a matter of moving the reflectors back a fraction of an inch to tame the upper midrange where it meets the woofer (~1.4 dB reduction) and consequently add a bit more in the 10kHz area.  (Every compromise has a tradeoff.)

Competition always brings out the best, even if its with oneself based on forum comments. 

Wanna see what I'm talking about???

@toddalin This is a perfect example of how to use the audio recordings as a tool for making adjustments to improve the sound of one’s system. This is exactly how I use the audio recordings. Well done.

@devinplombier Sorry wrong again. First of all there is no system remastering real-time transfer function adjustment implemented on my OKTANG6 system, whose recordings I shared here.

Second of all the system remastering real-time transfer-function adjustment system that I developed and implemented on my WAAR system is 100% analog, it is all done in the analog domain so there is no DSP in the system.

After developing and implementing the real-time transfer-function adjustment system on my WAAR reference system I challenged myself to develop a new system for my OKTAN6 where I could fine tune the resultant sound by making adjustment through the adjustable transformer based crossovers, again it is all analog with no DSP involved.

What you hear in the audio recordings is the sound that the microphone captures at the listing chair position without any processing or adjustment. None is needed as the system really sounds phenomenal and that comes through even through the audio recordings embedded on videos and uploaded to YouTube.

You are in fact mixing two different systems based on two different concepts that I conceptualized, design, and implemented all on my own.

Sorry to disappoint you but most of my work is original and one-of-a-kind in nature.

Why would it disappoint me? To the contrary. There is plenty of room in this forum for independent thinkers who chart their own course.
