Kal: if you will indulge me. I have a room size nearly identical to you with two openings to adjacent spaces: 4.9ft wide behind the speakers, plus 7.8ft in one long wall. I am likely to buy Blade 2.That should apply to all published graphs/illustrations.
What happened if you moved a Blade closer to a wall than 1m/39ins? Thank you in advance.
BTW it is wonderful to see comparison data 'using @pierre’s fantastic site here' (via post #49) of Blade 1 and Blade 2.
