Good question TIA,
The CS2 actually has a wider and taller usable sweet spot than conventional speakers due to its use of the large waveguide that provides a controlled radiation pattern over an approx 80deg angle. The benefit is that the off-axis frequency response curve is almost the same as the on-axis response. Speakers with dome tweeters or ribbons typically become very beamy in the high end of their response which means the frequency response curve of the speaker that is bouncing off boundaries (walls, floor, ceiling) is very different from the on-axis curve you are hearing in the direct field. These treble devices also exhibit a dispersion pattern that is too wide in the lower end of their operating bandwidth. This causes too much reflected energy to be in the listening window compared to direct field energy. Both of these issues taken together have a serious negative influence on response linearity as well as creating soundstaging and imaging problems.
Additionally, the CS2 has a low crossover point of 1kHz which eliminates the normal transition point to a tweeter in the upper midrange with its attendant problems such as abrupt dispersion pattern changes and passive crossover induced gremlins. We use an active, electronic crossover with very steep 8th order filters to reduce interaction between drivers.
All said, the CS2 sounds very live all around the room and provides a wide useable listening window for multiple listeners.
