PMA napsal:Já bych s názorem že stačí výkonová charakteristika a frekvenčka ...
To ani nikto netvrdí, len som upozorňoval na to, že simulácie treba chápať komplexne.
V tom citovanom materiály sa tiež uvádza:
"Double-blind subjective evaluations of loudspeakers conducted by the author and his colleagues for 35 years have shown consistent preference for those having flat and smooth on-axis frequency response, accompanied by wellbehaved off-axis response—i.e., a smoothly changing or constant directivity index ([1] chapter 18). Changing the room has little effect on this observation"
a tiež:
"In this example, the poor off-axis performance dominated the in-room measurements and in listening tests caused audible timbral degradation. Equalization of the room curve will destroy the only good performance in the loudspeaker—the on-axis/direct sound response. Equalization cannot
change loudspeaker directivity; the remedy is a better loudspeaker"
a toto je tiež dôležité:
"The double-blind subjective ratings were essentially unchanged as the test was moved from room to room [59](this is elaborated on in [2] section 6). Listeners were able to separate the timbral signatures of the loudspeakers from the timbral cues added by the rooms."
Ak by sme sa snažili v prípade tejto konštrukcie o vyrovnanú charakteristiku v osi, tak garantujem, že by to bolo nepočúvateľné a ukričané v stredovom pásme v najkritickejšej oblasti. Bol by tam obrovský prebytok výkonu.
