A good solution which you should follow even if you have a gap, is to tilt the speaker. You should do that anyway by pointing the speaker to the sweet spot (doing so means that the best sound of the speaker, the direct sound, is heard by the guy paying for it). By tilting it you are reduce the bouncing back and forth. You can hear the effectiveness of this in the above test.
Would it be better to lose the enclosed cavity of wall therefore possibly reducing the response of the speaker or following your advice to reduce the comb filtering effect? I could build an MDF box for the speaker and place it at an angle in the wall. Either way, thanks a lot of the useful info!
