Hi @tt33 ,
The whole expalnation will take several postings - mostly to make it easier to respond to any questions that come up regarding the specific topic covered in the posting.
This is the First Posting and represents the Introduction:
The intention of these postings is to provide owners of Linn DSM streamers a precise and accurate method to extract the maximum performance from Linn Space Optimisation.
The method substitutes the key concept of the Linn method - specifically the use of the ‘Tune Dem’ method to evaluate the sound (i.e. “if it sounds better, it is better”). This concept is included – but only at the very end of this method – and only as a final check.
The reason why I consider this method superior (to the Linn approach) is because Space Optimisation uses Computational Fluid Dynamic (CFD) modelling - which in practical implementation has demonstrable limitations (and which Linn have attempted to mitigate):-
- Without acoustic measurement for confirmation, Linn SO (CFD) may inaccurately compute the centre frequencies of the predicted room resonances.
- Without acoustic measurement for confirmation, Linn SO (CFD) may inaccurately compute the decay (in time) of the predicted room resonances.
PS: Later, I may include a posting on the general limitations of Computational Fluid Dynamics - but that will be to help inform and educate for those interested - it is not necessary to understand to sucessfully apply the method.
Note: I should mention that personally I like a very ‘dry’ sound with very short reverbaration times. I have my own media room with lots of acoustic treatment fitted. Neverthless, the practical examples used thoughout will be for more ‘regular’ rooms.
