Rolski,

Thanks for the room dimensions. Assuming your speakers are tucked in the corner as you indicated, it might be very helpful if you could move your couch 60 to 120 cm toward the front wall. It will get your head farther away from the back wall which can help with the bass response among other acoustical issues you're probably dealing with.

The height of your ceiling and the "flimsy" doorways work to your advantage in allowing energy to escape or diffuse.

Simply try putting a chair between 305 cm and 365 cm from your front wall and listen before you ask if you can move the couch.


Regards,
Bill
