Front speaker placement, trying wider placement.

Check out Acoustic Fields. He just posted a new YTV that you should find very helpful

The wider stance moves you forward in the venue and makes the listening position more critical. Moving your head just an inch will corrupt the image. You also dramatically decrease the volume or power at the listening position as it drops off at the cube of the distance. The B+Ws are not directional so you need absorption on both the side and front walls as well as the ceiling or you will be missing detail and again corrupt the image.

So b&w create lots of reverbs?  They do fill room with less of the narrow focus that other spkrs may have.  
Moving head one inch to change sq seems absurd.  Very poor speaker design if true.  Too little dispersion seems awful.

@tweak1, not a big fan. I think his thinking is more aimed at studio situations. He talks as if all loudspeakers are the same and they excite the room in the same fashion. This is definitively not true. There are many speakers that are not omnidirectional that can be placed close to a wall without ill effect. He believes in putting subwoofers in the middle of the room up on stands or hanging from chains trying to avoid "room gain."
Solid floor and walls are essential in a listening room. Subwoofers are 6-9 dB more efficient in corners which means they do not have to work as hard lowering distortion. Frequency response anomalies can be best managed by room control. Low E on a bass guitar is 40 Hz. Just because the room pushes 40 Hz up 6 dB does not mean that the harmonics and side bands which tell you what kind of bass instrument you are listening to, are up 6dB. If you have a lot of harmonic distortion sure but, that is another problem a good system should not have. I get the sense he is selling his expertise and acoustic treatment.
I love the room he uses as an example, the one the client uses for "storage." It has every acoustic treatment known to man stuffed in there.
Fortunately, It is being used as an example of what not to do.
