As mentioned earlier, I purchased M106 because I would love to a) eventually stand-mount them in a 2ch rig or b) trade them in on F206/208, and philosophically I'd rather buy excellent gear that can be useful right now and also later.
Thus far, I've been resistant to add a subwoofer partially due to the fact that my room constraints won't allow for optimal placement. There's a large fireplace that protrudes from the front wall to the left side of the TV, and the right side of the TV is visible upon entering the condo, so I've resisted putting something on that side of the TV cabinet. (You'll note a rather odd looking traffic-cone-colored toy to the right side of the TV cabinet in one of the pictures I snapped this morning - an indicator that this room is very much shared with a 30lb human). I think the left side of the TV cabinet is the only spot where I could "sneak in" a subwoofer.
Also attached the Anthem room report for the M106 for anyone who is curious about the response with this current setup.
Thanks again everyone for the input and comments so far. It's really helpful to hear from the community.
OK, can definitely see some of your challenges
. BTW, the ARC report shows very good response before and after calibration - which pretty effectively demonstrates how good the Revels are even straight out of the box. The ARC report talks about bass response post-bass management. Is bass management "on" in your Anthem? If it is, it needs to be turned off since you don't have a sub. If it's on when it shouldn't be, some of your bass is getting "shaved off" and the speakers could sound a bit anemic.
Here are some "speaker placement 101" ideas that you could implement that could really help with soundstaging and imaging, but I'm not sure how attainable they are in your room:
Ideally your speakers will be at ear level. Due to the wide dispersion of the Revel designs, this is slightly less critical than with some other brands. However, lowering the speakers so that they are more in line with your ears is a good idea. It will also bring them more in line with the center speaker. If it is impossible to move the speakers down, you can try tilting the speakers downward so the tweeters are firing more directly at your ears (an old mix studio trick).
Ideally your speakers will form an equilateral triangle with your listening position. This is one of the most important things you can do to help broaden your soundstage and get more of a sense of spaciousness. If you are sitting about 12 feet back, your speakers should also be about 12 feet apart. This appears to be the biggest challenge in your room. And, while this will help tremendously with music listening, it will also mean that the speakers will be quite wide in relation to the size of your TV. This could be a bit distracting when watching movies.
I don't know if any of the above helps, as I can see how the room layout may prevent implementing some of the above ideas.
The best place for a subwoofer is where it gives you the most even bass response. That could end up being a variety of different places in your room. If you are up for it, you can always try the Audioholics subwoofer crawl:
Sometimes the best location is not anywhere near the other speakers
