It is the reason why the best headphone and the only one i like is a Hybrid with a dynamic cell specialized in bass and a electrostatic cell specialized in higher frequencies over 4,000 hertz the cross over slowly decreasing point for the two cells..And a grid of Helmholtz tuned resonators inside to clean bass and mid bass... it work so much well that none of my past 9 headphones compared one second to the K340... All are under my bed for eternity or for computer use... 😊
The AKG K340 can make a soundfield more defined and clearer than my speakers because of what atmasphere explained so well...
My room dedicated acoustic so well it was tuned , was limited by my Mission Cyrus speakers under 50 hertz...And their tweeter limitation and roll off..
When i lost my dedicated room i was sad... When i optimized this headphone i enter in sonic heaven anew but with no more too much acoustic limitations... A well optimized modified AKG K340 rival any headphone today... It is the only successful hybrid headphone where one of the cell is not only a super tweeter as the dharma was..
Any designer in audio is an artist not only a scientist... because he must work and jugg with many trade-off at the same times... The designers who are not artist are not the great one , they apply a recipe...
