I have played around with room acoustics over the last few months doing my own thing using some second hand acoustic panels and some I made myself .
Bearing in mind my system sounded very good with no treatment at all, the improvement with my unusual acoustic treatment is huge and very worthwhile.
A HiFi enthusiast recently came to look at some speakers I am selling, he has a valve hybrid amp and sonus faber speakers and uses a modified Cd player with a valve output stage.
He had a breif listen to my system and within a minute of the first song he turned to me with a shocked expression on his face and said, " I have never heard a system ever in my entire life in which the speakers completely dissapear and leave a three dimensional image of just the music, real music right in front of me wow, I have read about this sort of sound in HiFi magazines but have never experienced it not even at hi end HiFi shows, can I take your system home with me PLEASE."
To say I was chuffed would be an understatement. *biggrin*
Some pictures of my latest treatment positioning.
Electro what is the wooded slat things in the corners? Whats your goal with them?
All your mid range and high freq fire forward only and by the time the reflect back in your size room they will be well down of volume mate??
Thats where your bass collects as thats omnidirectional from the speaker ??
I guessed you might ask me that *smile*
As you know when you came round some months ago there was a large bass null in the middle of the room and much of the bass was collecting in the corners of the room behind the speakers .
Logic dictates that bass traps in the corners would make a substantial improvement but when tried it the sound was far worse, the image dissapeared and the bass was thin and weedy in comparison. So I tried floor to ceiling bass traps, even worse.
So I scratched my head for While took the whole lot away and started again.
It then struck me that low bass frequencies are very large so if I put the traps either side of the corner and not directly in the corner the bass would not fit into the void and it would be forced out into the room rather than absorbing it.
The results were stunning, huge powerful, even, clean deep bass spread all round the room and the image came back with a vengance.
I then added the panels back in at the first relection points and a couple more bass traps to the left and right of my listening position which made a subtle but worthwhile improvement.
The treatment on the floor came about by accident after my wonderful sons thought it would be great fun to run into my room and push over my cylindrical traps and after shouting at them I realised that the sound was better with four of them on the floor next to the wall so after a bit of moving about and fine tuning that is where they stayed.
The next step was to hang heavy curtains over the wood and glass bi folding doors that are 7 to 8 feet behind my listening chair, this really cleaned things up and the imaging was vastly improved.
Finally after looking at pictures of treated room I noticed that many rooms have diffusers on the wall behind the speakers so I thought I would bodge some up out of some old louvre doors in the garage.
I put them in the usual place and they made little or no difference which dissapointed me so I slid them across the wall stage by stage into the corners and suddenly the whole sound sprung up into a new level of detail and focus, I then took the apart and made them floor to ceiling which was the icing on the cake and that is where they stayed.
I am sure you think I am totally mad and unscientific but the sound speaks volumes. *good*
