Linn Konfig Space Optimisation & Space Optimisation+

Linn Space Optimisation is currently configurable using either the Konfig app or the Linn Account Manage systems.

Click the above picture/icon for more information of that version of Space Optimisation.

More details of what Space Optimisation can be found can be found at www.Linn.co.uk

What are the differences between the Konfig Space Optimisation and Linn Account (Kloud Konfig) Space Optimisation?

The new version of Space Optimisation uses highly sophisticated acoustic modelling to model the interactions between your speakers and the room; this acoustic modelling is based on the finite-difference time-domain method. A simple two-dimensional analogy to this method of acoustic modelling is of a fishing net laid over a pond; each knot in the net defines a discrete measurement location, so that when a stone is thrown into the pond, we can track the resulting ripple by measuring its height at each knot.

The spatial discretisation employed by this method of acoustic modelling allows the new version of Space Optimisation to correctly consider the effects of:

• non-rectangular rooms;
• the placement of features like doors and windows;
• And the location and rotation of your speakers.

Furthermore, the time-domain formulation of this method of acoustic modelling means that the new version of Space Optimisation can now reduce both the energy and decay time of any artificial distortions caused by the interactions between your speakers and the room, resulting in both a flat frequency response and a uniform decay time. :Finally, the new version of Space Optimisation has been designed to give a better balance of low- and mid-frequency energy.

What is the difference between Space Optimisation & Space Optimisation+?

This is applicable to both Linn Konfig and Manage System/Kloud Konfig

Space Optimisation is for NON-Exakt systems. This uses the direct analogue outputs of the Linn DS/DSM

Space Optimisation+ is for Exakt speaker. This is used for loudspeakers fed via the Exakt-link AND used with as a digital crossover.

The "plus" is to signify the more musical detail that is capable within the Exakt system and Space Optimisation due to timing control of each individual drive unit etc. (This is not possible with non-Exakt systems as the loudspeaker is only driven by one common audio feed per channel.)

Is the Linn Account Manage systems only available for the new Linn DSM's

Both Applications can be used for ALL Linn Products.

The only limitation is that the Linn DS/DSM must have Davaar64 to run Linn Account Manage systems]

Why don't you use a Microphone in Space Optimisation?

The aim of Space Optimisation is to remove the effects of your room, to uncover the unique acoustic characteristics of your speakers; after all, this is what you fell in love with when buying your speakers. To achieve this, Space Optimisation needs to understand both the interactions between your speakers and the room and the unique acoustic characteristics of your speakers; the unique acoustic characteristics of your speakers are then subtracted from the interactions between your speakers and the room, leaving only the effects of your room.

An acoustic measurement of the interactions between your speakers and room can have many sources of error which may affect the accuracy and repeat-ability of the measurement, including the choice of measurement stimulus, such as MLS or a log chirp; external noise, such as traffic noise and vibration; quality and calibration of the microphone, which can introduce distortion; and the microphone location, which can be sensitive to within a few centimetres. The use of acoustic modelling removes these sources of error: the model can apply an ideal impulse as stimulus; the modelling domain is free from noise; the model can use an ideal microphone; and the listening location is well-defined. It can thus be seen that acoustic modelling has a clear advantage over acoustic measurement in understanding the interactions between your speaker and the room.

The unique acoustic characteristics of your speakers depend on many factors, including the shape and size of the drive units and ports; the constructive and destructive interference between the drive units, ports and any cabinet-edge diffraction sources; and the angle between the listening location and your speakers. Therefore, a simple on-axis anechoic measurement of your speakers is insufficient information; what is actually required is an anechoic measurement with your speakers in the same configuration as you have them in your home. While some manufacturers do publish anechoic measurements of their speakers, both on- and off-axis, it is extremely unlikely that they will have performed an anechoic measurement of your speakers in the same configuration as you have them in your home. The acoustic modelling of such a scenario is, however, straightforward; the model can simply turn your room into an anechoic chamber to obtain the unique acoustic characteristics of your speakers in the same configuration as you have them in your home. It can thus be seen that acoustic modelling once again has a clear advantage over acoustic measurement in understanding the unique acoustic characteristics of your speakers.

From the above, it is clear that acoustic modelling is the best approach to Space Optimisation.

Can I use "Linn Account Space Optimisation" with my Exakt system?

From November 2019 you can now use Linn Account Space Optimisation with Stereo and Surround Exakt systems.
