It maybe part the components quality part the subtle value fixes but we must not forget that George has speakers that let him hear things that our systems may well hide, and we probably can't relate directly to what exactly he hears more. I know because I had listened to them carefully since we had to judge and fine tune their 3way crossover we made. Those are large scale modular horns of the best ilk. Aided by high sens & power huge active subs. 4 way multi amplified system in total.

I got bigger improvement by changing these 2 resistors, something I didn' t expect to be really honest.
FT-3 comes across more mellow and K-72 a bit edgier when using tweeters in my experience but that may well be more info in reality that does not bother the Le' Cleach with the land mine size Great Plains driver you use almost over to 10kHz. It could be highlighting 3rd order nasties in one inch low crossed tweeters on the other hand. Which even the best are toys in dynamics VS THD comparison to such horns. So it can be working better for you. Those Z Foils are technically superior resistors indeed, but parts outlay must always go in tandem with the resolution that an installation can provide as a whole. I.e. logical in your case. So get/make the best speakers you can in good proportion to the room before spending lavishly in parts is a good rule of thumb for any of us IMHO. Orelli had great results too but look at his speakers and room treatment...Impressive. (#7849 & #7850).

Its all in the PDF linked from post #1. The mods you see I breadboard lately are not properly developed or confirmed positive yet. But some parts I needed are on their way.

Hi Ricardo,

here are the values I used :
R4=6,790K
C1=46,94nF
C2=15,080nF
C3=47nF
R14=46,93K
R1=180R

Salas, room treatment, I know, is on my shortlist for the winter!

Perfect.
Using your actual values I see a slight rise in the highs and a recession in the upper bass as in the graph.

You can experiment by lowering R4 to 6775ohm (by paralelling a 3M ohm) and then tune trebble according to your system by adding between 40p ~100p to C2.

You will reach the following result:

But if you like your sound, do not touch it... Your setup is very good... as is the result is 0.05dB off target
