Combine soundbar with in-wall rears - good idea?

The biggest problem I see you running into is how the room is setup. You can easily run a front surroundbar and 2 in wall rears. I just checked the polk audio site and with there surroundbar which is a 5.0 speaker they recommend:


Good - Hook up two rear channel speakers to the surround channels in the usual way but connect nothing to the rear channel inputs on the Surround Bar. In this case the Surround Bar is being used just like a conventional L/C/R sound bar. You will get all of the audio performance of SurroundBar for the front Left, Center, Right channels and the conventional rear channel performance from your hard-wired rear channel speakers. The surround drivers in the SurroundBar are simply not used in this option.

Better - Hook up the rear surround speakers as in 1) above but also connect the surround channels of the receiver to the rear channel inputs of SurroundBar. The hard-wired rear surround speakers must be 8 ohms or greater for this option. This option will give conventional rear channel performance plus the wrap-around soundstage of SurroundBar, which will fill in the sides of the soundstage.

Best - For the best alternative, if you have a 6.1 or 7.1 receiver, hook up either a single rear channel speaker or two surround back speakers to the "surround back" speaker outputs of the receiver. Then, hook up the rest of the channels, including the left and right surround, to the SurroundBar as usual. It combines the ability of SurroundBar to deliver continuous wrap-around soundstage with solid rear imaging from the single hard-wired rear speaker(s)

So as long as you have a capable receiver that can do Audyssey Multi EQ or something similar to adjust everything if you dont plan to to do it yourself ya should be fine.
