5. Running In
The performance of the speaker will change subtly during the
initial listening period. If the speaker has been stored in a cold
environment, the damping compounds and suspension materials
of the drive units will take some time to recover their correct
mechanical properties. The drive unit suspensions will also loosen
up during the first hours of use. The time taken for the speaker to
achieve its intended performance will vary depending on previous
storage conditions and how it is used. As a guide, allow up to
a week for the temperature effects to stabilise and 15 hours of
average use for the mechanical parts to attain their intended
design characteristics.

6. Aftercare
The cabinet surfaces will usually only require dusting. We
recommend you use a soft microfibre cloth. If you wish to use
an aerosol or other cleaner, apply the cleaner onto the cloth, not
directly onto the product, and test a small area first, as some
cleaning products may damage some of the surfaces. Avoid
products that are abrasive, or contain acid, alkali or anti-bacterial
agents. Do not use cleaning agents on the drive units. Avoid
touching the drive units as damage may result.
