So he should do what particularly since he's not likely to change rooms?
Given that the - 3dB point with the main speaker is 80 hZ, I would want to optimize corner loading, first. I would not recommend expensive solutions (including the best available equipment) in a room with so many likely sources of destructive interference.
Given the volume of the room and the multiple corners, I'm doubtful the mains are placed optimally and the Hegel amp has sufficient headroom to generate higher SPL.
My guess (and it's just that- a guess) is that the setup is quite new and the OP is disappointed with the performance in this unusual room.
Color me doubtful that meaningful bass material below 40 Hz is likely given the first two side wall lengths.
