I'm with Randy, as soon as I saw that picture the W series was the first thing that I thought of all it would need is some minor work to close off the opnings to the correct size of the mounting bracket. They would look incredible with that set up. The other option would be the T series, in-wall. I was thinking the T80 and simply remove the panels at the bottom of the columns to get them mounted,, if there is enough depth to handle a a ~20" depth. Either way I beleive these would give you better overall performance as the rear port on the M22 will not be much of a factor and most likely alter the sound of the M22. Since you have already ordered them it will be interesting to read your opinion of them placed in that area. Just remember you can always send them back and trade up to the 'W' series.
