I have got three pair os speakers, the salk Song towers, sierra 1 and Selah tempesta.
They all sound wonderful, but what i found is that the sweet spot and center image differs.
For example, both the song tower and sierra are very easy to set up and can have good center image, even if they are close to walls and poorly placed.
The tempesta has the best sound quality but i find them to be harder to get a wider sweet spot and center image. It seems like they need to be brought out from the front wall to get a good center image, but even though the sweet spot seems to move to the speaker rather then staying in the stage.
Any thoughts? What make a speaker have good image and wide sweet spot and less fussy about placement?
