Line Array Speaker vs Point Source Speaker


.
Is there any inherent advantage to either of these speaker designs?

"The so called 'point source' is an attempt to construct a
microphon in the 'reverse': as a sound source. The only one
that works or that I know of is the Manger midd/high speaker. The Kef and the TAD are actualy a compromise."

The CLS Walsh type drivers in OHM Acoustics Walsh line speakers actually approximate a very wide dispersion (pseudo omni) point source extremely well in most setups, especially in but not limited to the horizontal plane.

The key difference between a well executed line source versus point source is mostly in the geometry of the sound dispersion pattern which is a primary determining factor for imaging and soundstage.

Whether point or line source works better in this regard has largely to do with size, shape and perhaps liveliness of your listening room, the location of the speakers within it, and your location as the listener within it as well.
All of the line source speakers I have heard in my life sounded better and played with less distortion to my ears than any point source speaker. Line sources are better but they are much more expensive. The best usually is.
The speakers I use and sell have single drivers...they just happen to be very large and are designed to operate as full range virtual line sources.

Agree, expensive line source designs with multiple drivers are probably best in general for larger rooms where you want to go loud with lower distortion.

For smaller rooms, fewer drivers and designs that simulate a point source more work better in general. Some with larger drivers like the larger OHMs in particular can work very well in larger rooms also.
