So, where does one go to listen to cinema speakers (other than the cinema)? I've been toying with the idea of upgrading the speakers in my own screening room for a while, but haven't done anything yet. This isn't like buying home stereo speakers, where it's fairly easy to find a dealer who will let customers play a familiar record/CD on different speakers in a controlled environment, and where most speakers are small enough to be easily exchanged or re-sold if the result in one's home is not satisfactory.
I've heard lots of cinema speakers in cinemas, but I have a hard time correlating sound quality with speaker brand/model. There seem to be more differences in the room and system setup than in the loudspeakers themselves. I've heard both good and bad sound in theatres with Altec, JBL, and Electro-Voice speakers. I've had relatively little exposure to the QSCs (they are too new for most of the places where I have worked).
In general, I have been unimpressed with PA speakers used in cinemas. I have done this on a couple of occasions, and I agree with the comment about the importance of keeping the crossover point outside of the vocal range. Many portable PA speakers that sound great with music will completely fail in the dialogue intelligibility area, which is the most important function of cinema speakers.
The best cinema sound that I have heard was at the Cinerama Dome in LA in 2000. I hope that the system there still exists and still sounds good.

I agree that SOME 3-way systems sound worse...but the QSC's for one do not.
The main reason I prefer three way designs is very simple and stated in QSC's description of their 3-way systems, the crossover point is, at BOTH ends, outside of the "meat" of the dialog frequencies. Thus only the midrange driver carries the main workload for dialog. This reduces the problems caused by poor time alignment, lobing and and response errors at the crossover points.
That, to me, makes a three way system the ONLY proper choice for the majority of cinema sound systems. (Just look at the F-T Screening room.) And to my ears, a properly set up three-way system sounds clearer than any two-way system I have encountered in the 30+ years I have been doing this.
BUT, and this is important, the ROOM design and treatments can easily make or break the sound quality of ANY speaker system, two-way, three-way or any way.
