Spinorama or not Spinorama... is this the question?
pls ask to Floyd Toole, best speaker is the one with flat freq response on axis and coherent off axis.
why?
because "those ones" shows highest correlation with educated listeners judgment
so what?
because we do not listen in anechoic chamber or soccer fields but we listen inside our houses, between walls, floor and ceilings. so speakers that has lower interaction with the room better reproduce the recorder message (music,sound,...).
so what rooms do?
Room introduces reflections that create picks and nulls in the freq response... coloration.
what we can do?
minimize room effect, (by improving spinorama is only one piece of the mission).
who do this better?
speakers that "DIRECT" sound to listeners and avoid to spread it elsewhere. Cardiodid? yes! Pro sound knows this since played in educated market.
we need to avoid early reflections and eventually (since we can't) have early reflection similar to direct sound.
if above is correct (science is based on verified experiments and theories) i derive the following:
Best (regardless of spinorama) Speakers are:
B&O 90
Kii three +BXT
Kii three
Dutch & Dutch 8C
...
...

among not Cardioid
JBL M2
Genelec ...
pls. agree or disagree but pls. explain why, your opinion count and will help everyone.
