DO "one-point-source" type spkrs ZINGALI need To

Hi, I am wondering if the so called "One-Point-Source" type spkrs, like Zingali floor-standing spkrs, need to be Toe-In ?
I assume that the need for spkrs Toe-In is only applicable to the conventional spkrs
THANKS in advance

Toe-in isn't so much something you "have to do" with directional speakers, but something you can take advantage of with some. See
Zingali's have seperate bass drivers to go with the horn loaded midrange/tweeter driver. You still have to experiment with toe-in. I have single driver Lowthers and they sound different with different amount of toe-in
