I've been working on my room for over a year from zero knowledge about acoustics to what I know today with the help of Audiosciencereview forum which triggered the whole thing for me. I think I've reached some kind of a milestone to share the BEFORE and AFTER comparisons of how Room Treatment, DSP and more subs can change the overall room acoustics. It all started when I had an untreated room with a couple of Revel M16 speakers, a single Yamaha subwoofer and no DSP.
My room is a weird shape with multiple open spaces to corridors and 2nd floor. It has a very high (6 meters at the highest point) vaulted ceiling with protruding beams. The speakers are NOT equal distance from the side walls also.
Here is a quick sketch of it:
This is how the room sounded with 2 speakers, a single sub, no treatment, no DSP (1/24 smoothing) BEFORE:
RT60 (Topt) BEFORE:
Waterfall BEFORE:
I've been working on the room and acoustics throughout the year without prior experience.
Eventually I purchased 2 x SVS SB-1000 Pro subwoofers to accompany my Revel M16 speakers. Placed the subs at the back corners as best sounding spots in my room. Removed the old Yamaha sub. Installed and tuned DSP Parametric EQ manually. Installed a bunch of velocity and pressure based acoustic panels and bass traps. In total 10 broadband pressure based 3 inch, 80kg/m3 rockwool DIY bass traps / acoustic panels, 8 foam based Auralex LENRD bass traps (all the way from floor to ceiling) in problematic corners and 2 Auralex freestanding sound deflectors. I did not block early reflections because I didn't like the sound without the reflections. Revel M16 can boast outstanding off-axis response. It's a sin to block their horizontal reflections. The sound stage expansion is audible without any measuring equipment. I don't care about vertical reflections against the ceiling becuse it's so high and it's vaulted, it just redirects the sound waves elsewhere. The carpet on the floor takes care of the floor reflections to some extent for me.
Here is the room treatment distribution as it is today and as I like it:
There is an air gap between all panels and the walls. I like reflections, hence all sound absorbers are in the corners, except for the deflectors which simulate equal distancing from the side walls.
The sound is adjusted across the 3 seater lounge via DSP EQ as an average best between all 3 seats. There is no central seat as a matter of fact. It has just 2 wide cushions so one is seating either on the left or on the right.
This is how the room SPL looks NOW (1/24 smoothing):
LEFT SEAT
CENTRAL SEAT
RIGHT SEAT
RT60 (Topt) AFTER
Waterfall AFTER:
Hopefully someone will find this experience and comparison graphs useful. I learned all about it from the forums only. I tuned the system to how I liked it best, only later to realise that it actually resembles the popular House Curve. Well I just trust my ears above all in the first place.
