Always great to hear how to improve your sound. And, it is simply loudspeaker positioning that is the answer. Unfortunately, it does take years of experience to understand how to improve the sound so I will give you a good insight.
Listening and testing take years to know exactly where to place the loudspeakers. And, have written this “How to improve sound ” article to help you understand. It is easy to do but what a difference it really makes by positioning and repositioning those loudspeakers.
The system I am writing about was set up in Vilnius, Lithuania and the loudspeakers made by “WOLFVONLANGA” open baffle design
The article will describe some of the faults I found in the original Speaker system set up and also the corrective steps are taken. Initially, the sound had a score of 5/10 but after the adjustments, we finished with a score of 10/10. The system had been running and burning in for a month and I was invited over to my friends to listen and tell him what I though of the sound from the system.
I took this picture as I entered the listening room, which could be used as a reference for making any necessary adjustments.
The loudspeakers were large and looked so impressive with the design and construction. I liked the look and the feel of everything and was really expecting to be literally “blown away” with the sound!
The music coming from the system was nothing like I expected to hear in any way shape or form. My friend told me he had carried out tests using his computer “set up” and was interested to hear my thoughts.
The sound I heard was completely wrong and was way out of balance. The bass was booming and overbearing. The vocal appeared from two-thirds of the way up the wall. There was nothing happening in the middle of the sound stage.
The details were just appearing from the far walls and there was no feeling whatsoever in the music. The sound was lifeless and flat without expression. Also, it was apparent that when a note was played it was quickly cut off.
After the CD finished, a Rod Steward LP was put on the turntable. This was done to let me hear how vinyl sounded in the system. When I heard the sound my words were “Rod what has happened to you?” Why did Rod sound so thin and was half-way up the wall!
This was the initial position of the loudspeakers when I arrived.
The left speaker was just too far away from the rear wall. And also too far away from the right-hand speaker. The toe-in angle was wrong, causing the reflection, and the hole in the middle. Also, the loose boomy bass and the vocalist appearing two thirds up the wall.
The first task was to move the speakers 25 centimetres nearer to the rear wall and 25 centimetres closer together. Luckily the units were on wheels and easy to move and also the initial position I chose turned out to be very good.
`The move was large compared with the room size.
I want to point out sometimes it is only necessary to move a loudspeaker just a few centimetres. And then fine-tune by moving just a centimetre or even a half centimetre.
One of the things I found necessary was the small adjustments that were needed. This was because the open baffle had a critical adjustment to sound direction. Which, was a major player in how to improve sound quality!
By moving the toe-in angle on the loudspeakers a very small amount, it was possible to have the vocals exactly where they should have been and this was “centre stage”.
The loudspeakers had to have a very small toe in. Which, was about one centimetre off centre which was enough to make the sound dispersion correct.
The loudspeakers ended up with exactly the same measurement from the left driver centre to the right driver centre. This measurement was the same as the measurement from the listening position to the centre of the loudspeakers. By doing this it is possible to create the “sound triangle”. The “sound triangle” is something that should always be used because in most systems it gives the best results.
The initial adjustments had been completed. And we took it in turns to sit in the listening position to hear the results. A few more small adjustments were made and the system started to sound great. The bass was tight, The vocals were centre stage and the sound-stage excellent. The system was now up to 9/10. But something was not sounding quite right. If you remember, I said the notes seem to be somehow cut off and there was a certain lack of life to the music.
At this point, we decided to try different cables to see if there would be any difference in the sound. My friend took a set of interconnects and loudspeaker cables (which were the new 1.3-meter Interconnect and the new 5-meter speaker cable he received only a few days earlier) from his Tannoy system and connected them up.
I am even impressed with my own cables. Because it was all that was needed to bring the system to life! The music was now alive with feeling and presence. My friend put on Rod again just to hear what he sounded like. Rod was real as if he was in the room with us and the sound we heard was now a full 10/10!
Everything sounded great and I even found myself singing along with Rod as the harmonies came in! They say there is a first time for everything and I think the sound from the “WolfvonLanga” system really got into me!
How to improve the sound quality of your system can be addressed in just two ways.
The first step is to reposition your loudspeakers. This is something that is often overlooked and people spend thousands on their systems. And, are not getting the full enjoyment. Often, because they have not been told about the importance of this basic procedure.
The second step is to use audio cables suited for the purpose. Meaning, the cables are transparent and does not add or subtract from the original signal.
