Well, since you asked:
sure you can't for all rooms, why would ya? Because sometimes a studio has more than one configuration, and when things are moved around, it becomes a different room with different response characteristics. Also, unless you've got a resident passive crossover genius on staff, there's no way the typical studio can put the same kind of monitor in each of its studios, control rooms, or mixing rooms with just a middle of the road stock crossover and extract the best from the speaker or get consistent room-to-room response.
i'm sceptic to try to correct room problems via some kind of equalizing and stuff, not for all listening positions. Room "problems" meaning what? The primary utilization of these monitors is in professional environments which will have had some thought given to room design and construction. These rooms will have different sonic characteristics no doubt, but not the kinds of problems you'd find in virtually every home environment. There aren't going to be big openings into a kitchen or a vaulted ceiling open to the second floor or a giant double doorway between two large rooms or hard tile floors in a studio environment. In the professional environment the sonic differences will be easily addressable through calibration to get consistent room-to-room response.
i'm talking in home industry. These are not home speakers intended for the typical "put it anywhere and power it with anything" consumer. They're Master Reference Monitors for professional applications.
maybe this graph is what it's all about (listening axis response inluding room reflexions): That's what it's all about in the space where it was measured, which is unlike any space in which it will be installed. These kinds of graphs are useful to compare speakers with each other if the measurements are done in the same way and under the same conditions. But once the speakers are moved out from that testing environment they are placed into a world that's very unlike where they were tested. What the graph does tell us is that the speaker is capable of that response, but it's up to the user to create the conditions that will make it possible. JBL/Harman is saying, "We can give you that if you use our whole system to set it up in your environment. If you don't, it'll still be pretty good, but it won't be as good as that."
zorg43x, these final comments are not directed at you. They're just general observations.
Since AVS has some accomplished pros who both lurk and post here, there might be 100 or so folks who have the background, experience, equipment, funds, and hopefully the free time to create something pretty close to what's in the M2 system as recommended. I bet 5 -10 of them could even improve on it. I doubt that any of them would give it to me for free. This stuff is expensive because it costs a lot of money to develop over a long period of time, then there's manufacturing costs, distribution, marketing, support, the list is long. So for something with this much potential to be priced as it is is remarkable to me.
AVS also has tens of thousands of enthusiasts who believe that a couple of google searches, advertorial opinions by people with clear conflicts of interest, and comments by people with a lot of posts carry more weight than hundreds of thousands of dollars of research, published AES papers, and peer-reviewed studies.
I'm in neither camp. I know I'm neither an accomplished pro who can make any significant contribution to the science that is before us, nor am I a witting tool for shallow analysis of complex ideas just because I can get a dummies version on Wikipedia or a watered down oversimplification from someone with a competing interest or a blast of hot, opinionated air from someone with 10,000 posts. I like to appreciate the honest, hard work of others who are better and smarter than I am in their field, and I like to learn why they do things the way that they do. Then I like to listen to it the way they intended and decide if I like it or not.
