Slim, I think you should have serenity_now come and tune your room and system. You should see the science he did with his room.

He also built his own 170 lb each monolith of a speaker. He'll have that room so tightly designed, you'll be able to graze with 1 cm resolution with no change in response.

And of course I need to come there too because serenity_now is not a professional engineer like me. You'll need his design stamped by me. I'll stamp the design using the blood that trickles out of my ear drums.
