I was 24 years old by a friend who made his own speakers and push me to buy Tannoy dual concentric gold... Thanks to him...
He know and read about engineering design of speakers and amplifiers with one of his other knowleageable friend..
But never investigate acoustic...
Then like him i never investigate acoustic like most audiophiles all my listening life till a few years ago...
I then discovered the huge power of acoustic treatment but way more powerful the power of mechanical acoustic control in a dedicated room ..
Things has not changed in audio threads most people talk about electronical or electrical measures and they have no idea that most of the S.Q. come from the room/speaker relation like my first mentor...They think that the capacitor choices is more important than the room ... 😁😊So important they are they are secondary compared to the acoustic settings power...
The electronic is like the brain engine, the room/ears is like consciousness, it is the driver of the engine...
He is dead i wish he was living and could listen the sound of my room now...
Because what we listen to is completely at 80 % speakers/room dependant...You can contest my number and take it to 70 %...The essential fact will not change...
