Thanks @2Brix @petetherock
Im not sure if these are diffusers as the wells seem to have the same depth.
The photo was taken at a Hong Kong Hi-Fi shop while I was travelling in HK last year. The room didn’t seem like heavily treated but the sound was truly astounding. These Rockport speakers produced some most uncanny imaging and holographic soundstage I had ever heard. The singer was so palpable, occupying a real human size space in the air. The experience was truly jaw dropping. Ever since then I acquired a pair of Audio Physic speakers which are also known for their imaging and soundstaging. I have been trying to duplicate the same experience in my room but I’m still not quite there after a whole years effort.
My current set up has bass traps in the corners, absorption panels at the primary reflection points on the walls and ceiling. See picture attached below. Some panels are sitting on the chairs temporarily : ). Once I decide on their final placement I will fix them on the walls.
Still trying to place some additional panels here and there but I’m not getting much depth not to mention a holographic soundstage. It’s getting a bit frustrating.
Any input is appreciated. Cheers.
