B&W 702s or Revel F208s

I would stick to the Revel over Focal. The Aria 936 can't match the Revel lower bass response, doesn't have as well damped cabinet, and presents a bit a load on a partnering amp. The Revel IMHO, is step up from this Focal model.

For those who use Revel F208s, for stereo / music only, do you guys use them with subwoofers or just them? Thanks

You won't need an additional sub with the F208's with the output going nicely down to the 20's in rather well. It's front ported, so it makes some aspects about rear boundary wall distance a bit less of a fuss. You also have a boundary compensation adjustment on the back that will slightly shelve the bass if needed. You would prefer to pull them out from the back wall like any speaker, but a boomy sounding bass is not going to as much of a concern as a rear ported design.

Due to the wide dispersion, try and steer clear of side walls as it will really hinder the imaging and sound stage. As with many speakers, the upper treble does fall off to the sides and toe in can be used to dial in the upper treble.   

I just borrowed the F208 from my friend for an in-home audition.

@mmeysarosh would 10” from side walls be OK? I have them over 2 feet from the back walls, so that should be OK.

also, tweeter to tweeter I have them 7.5 feet apart. Is this sufficient? I sit 8’ from the center image 

thanks!

Just to clarify, I'm assuming you mean the edge of the speaker being about ten inches from the side wall, which is generally too close to a side wall to prevent first reflections from the wall from image smearing.

What happens in this case is that the first sound you hear is the direct radiation from the speaker as it has the shortest distance to you in travel. Then sounds that are reflected from nearby walls, such as side walls and the walls behind you seated position. Our brain can differentiate from the direct radiation and reflected if the time between when they reach your listening point is far enough apart. This takes lengthening the overall distance the reflected sounds must travel until it reaches your listening spot. In general, you need at least about 5ft of extra travel distance to make this work. As you mentioned, the distance where you sit is 8' ft. In affect, we would like to see the first reflections to hit 13' ft in total travel distance to your listening spot over its two axis. What we would like to see is at least 3' feet of distance from the acoustic centers to the sidewalls. The same can be said for the rear wall behind your listening spot. You would want that wall about 3' feet behind your ears at your listening spot.

This often doesn't work in many living arrangements so the best alternative is to place acoustic diffusing or absorption at certain points in the room to improve the room acoustics. There are plenty of options our there and some can even be used as decor.

As for your distances between the speakers and from your listening spot, those are generally fine. I'm just wondering if room is rather small for something of this size or are we just close to one wall on a single side.
