Sweet Spot vs Speaker Dispersion


Well-Known Member
I was wondering where these two subjects intersect, and how one affects the other? Correct me if I am wrong, wide dispersion speaker gives a wider sweet spot but are not as focused in imaging. High directional speakers can have better imaging but sometimes can cause such a small sweet spot, you get the head in a vice syndrome.

I know some electrostatic speakers like Acoustat that are not curved. Can be very directional, with an almost holographic imaging effect. Which I think Flint said he disliked that effect as it was not based in reality, I thought it was very cool. I could swear their was a trumpet coming way off to the side of the speaker. That is what started my love of planer speakers, however if you were off axis about 30degrees or so the sound really dropped off a lot.
Opps forgot about this from my soundstage vs imaging thread by SH:

The sweet spot is dependent on the acoustics of the room and the dispersion of your speakers. Horns will have a more focused and predictable sweet spot than more omnidirectional speakers, which will have a more diffuse and room-dependent sweet spot.
