RoomPerfect took years to develop and there are over 50 elements protected by the patent. 20 years ago, Peter would be setting up room correction systems at shows and often it would take him all night to get the results he was happy with.
He started by taking a measurement at the main listening position but found this didn’t capture the room or the speakers with any accuracy. Move the mic an inch and you can get a very different measurement of higher frequencies.
This is why their unique measurement process was developed. If you don’t use it, you will definitely get worse results from RoomPerfect. If you like it then use it ,but I can 100% guarantee it will give measurably and sonically inferior results than using the process Lyngdorf recommends.
The initial measurement with the mic firing at the speakers, from the main listening position aims to capture the sound of the speakers and the characteristics of the room. This is because you would expect someone’s voice or a loudspeaker to sound different in say a bedroom or a bathroom because the rooms are different sizes and have different acoustics. As such its vital the system understand both the sound of your speakers and of your room.
This measurements allow RoomPerfect to create a target curve that s unique to your speakers in your room. Whatever frequency response your speakers have, RoomPerfect is unique in preserving it.
The second thing that’s very different with RoomPerfect measurements process is that you then measure across the full width, length and height of the room. If you room was 20m long, you should take a measurement say 18m from your speakers. All of your room’s acoustics impact on sound quality at every point in the room. Without understanding all of your room, you cannot get the best results at the main listening position or anywhere else.
Please use the system as Lyngdorf recommends, they know what they are doing and if it gave better results with all measurements taken at the same position, they would say so.
If you haven't watched the video posted early in the thread by Peter, you really should.
