Thank you Gleen! I've seen you've been very responsive and useful in other threads as well so really I do appreciate your contribution!
I watched both videos and read some stuff around as well but put simply there is not much I can do to my room. Is a room intended for living not as a control room so for example in the upper corners of the wall behind the speakers I have spotlights and neon lights extruded from the wall (and the room door as well). On the wall facing the speaker (behind my seat position) I have the bed (on one corner) and this big wardrobe covering the entire wall up to the ceiling with the wardrobe "doors" opening until they touch the lateral walls. Also on one of the lateral walls I have a big windows so I cannot but stuff there as well.
I thought of some improvements I could do to the room but... really I surrender to the idea this is not possible.
Bass is not much of an issue at the moment... I mean... I don't hear much bass, maybe beacause of the NS-10 speakers or maybe the room but I don't have this "bass" build-up effects, maybe the opposite.
Anyway since I have this issue in setting up traps or such (by the way the room is quite full of stuff that breaks angles, spaces and walls, is quite small wih a big soft bed and many fornitures) that's the reason I was wondering if an ARC-like system could be of enough use or maybe it's best investing that money on a good pair of headphones, coupled with a VRM-like system...
I really wish I had a spare room in my house to dress up like it should
I'm not a full time "engineer" it's just a spare hobby that goes together with many others so maybe I do a song then for 3 months (or years) I don't even open my daw.
