While I can't comment on the HF section of the 4622, the LF section (4639) is definately not as good as the 4670's LF section (4648) in terms of repsonse (flatness and deepness of bass). The 2380 horn used for the 4670 is not the best horn in the world and it has almost no control below 1KHz. If you have the depth, I'd put the JBL 4675 (bi-amped natch) up against all of the speakers listed above. It is the best sounding, most reliable and widest/smoothest response. The 8340A is a fine surround speaker featuring good response, great sensitivity, decent power handling, and pleasing sound. Furthermore it is lightweight and easy to install.

I would say the 4675 would not be a good choice for the steel and glass box...in such a situation, one is looking for "control" to minimize the room's contribution. In these situations, a horn-loaded speaker almost always is a better choice.As to the extra row of seats...is there any wonder that exhibitors compete for bankruptcy? Compromise the sound on ALL films so they can boast about seats they only fill periodically and when the percentages are not in the exhibitor's favor. One thing I have noticed on the 3-way version of the screen arrays is that their high-end drops like a tank above 12KHz. Does the 4622 suffer as well? It uses a different horn/driver (3" diaphragm) If it outperforms the the 2380 then it might make a good top-end to the 4648 LF cabinet in smaller rooms (the 2446 is a tough driver to beat in sheer output).

hi SteveI also admire the 4675C ! and I hope JBL doesn't stop them. It's also a sort of heritage ( but much better some say ) to the 1960's Altec Voice of the Theater i think ( I have seen these in a "normal" home theater! ) I would even go as far as installing it in large (12x6m+) home theaters behind microperforated screens (4-5meters screens ) on the 8340A, it seems thus the consensus is that's it a good surround.
