The speaker is now ready to be removed from the box. Have an assistant help you lift
the speaker clear of all packaging. Stand the speaker on the floor, taking care not to
damage the foot.
The protective polythene bag can be slippery, so great care must be taken. Once
both speakers have been stood up the bags can be removed and the packaging
stored for future use. The packaging is essential for shipping the system safely.

The Subject of Room Acoustics
Acoustics is a complex subject and this text should be treated for what it is, a simple
but informative guide. For a more in depth understanding you would need to refer to a
whole range of texts on the subject. The most important outcome of this should be a
greater appreciation of the role played by the room and surroundings on the overall
sound of the audio system. The air contained within the room is the link between the
output of the loudspeaker and your ear. How air behaves is dependant upon the
attributes or character of the room. It follows that a better understanding of basic
acoustics and what facets cause the most influence in the room will assist in making
decisions about the way in which the room and subsequently the system can be
improved.
Room types fall between two extremes. A room can be ‘dead’ on the one hand (full of
highly energy absorbent materials and complex diffusing structures) or very ‘lively’ on
the other (few reflective surfaces and a high proportion of very reflective, hard, non
absorbent surfaces). As so often is the case a balance of materials is commonly
preferable to one extreme or the other. The correct balance is the goal for the end
user.
Room attributes that can be easily changed
The contents of a room will impact upon its overall acoustic character. As you would
expect hard surfaces like glass and concrete tend to reflect a broad band of acoustic
energy. Complimentary materials that are soft and thick in section such as heavy
natural fibre curtains will tend to absorb a broad band of frequencies.
What are standing waves?
When sound waves reflect between two parallel surfaces, the distance apart being
equal to half the wavelength or less, dependant upon wave size, resonance modes
referred to as ‘standing waves’ are created.
