Preparation

Loudspeaker Installation

The Concept 50 loudspeakers are intended to be floor mounted only. We recommend you attach the support base during the unpacking process as in the diagram above, to avoid damage to the loudspeaker. However, you may attach it after the loudspeaker is unpacked, but you should protect the loudspeaker from damage by placing it on a soft cloth or similar. You must also take care to avoid damaging the drive units.

It is important to ensure that the loudspeakers stand firmly on the floor using one of the feet options supplied. The spike feet are designed to pierce carpet and rest on the underlying floor surface. The Ball-end feet should be used where there is no carpet and the floor surface might be damaged by the spike feet.

Whichever type of feet you use, the same procedure should be followed to ensure stable mounting. Install the feet as shown in the diagram above, ensuring they are screwed in fully. Adjust the feet until the loudspeaker is level and stable. Finally, lock all five spike nuts.

To avoid damage when spikes are fitted, do not drag the loudspeaker and take care to place it where it cannot cause damage or pierce mains cables etc. Used properly, spike feet will not damage carpets. For very soft wooden floors it may be advisable to use spike shoes or coins (not supplied) between the ball-end feet and the floor.

Concept 50 Isolation Base

The Concept loudspeakers are equipped with our custom suspension system, isolating the base from the main loudspeaker body. This isolating technology allows for a calculated amount of movement within the loudspeaker base so please do not be alarmed by this. On Concept 50 this can be locked if you wish to use your own isolation base, as shown in the diagram above.

Positioning

Foam Bung

Concept series loudspeakers are rear ported and designed to work best with at least 0.2m of free space behind them. Generally, the closer the loudspeakers are to the rear wall the more the bass frequencies will be reinforced until they overwhelm the overall sound. In this instance closing the rear port with the foam bung will tend to reduce bass, which is useful when domestic circumstances demand that the loudspeaker is used closer to a rear wall, as when wall mounted.

Ensure that the bungs are fitted snugly into the port but avoid inserting them too far. You will find the overall level of bass is reduced but bass extension and definition will be increased. The optimal position of the loudspeakers will only be found through experimentation and by making small adjustments during the first few listening sessions.

Loudspeaker positioning in a room is not an exact science. Even experts will find it necessary to experiment.

Try to achieve the best balance between bass quantity versus quality and vocal quality versus intelligibility.

Concept 30

The Concept 30 loudspeakers are ideally mounted on FS75 stands and can also be wall mounted on the WB75 wall bracket. Stand mounted loudspeakers should be treated as floorstanding loudspeakers except that the loudspeaker may be placed a little closer to the back wall.

Concept 50

The Concept 50 loudspeakers should be positioned at least 0.2m from a back wall, 0.5m from the side walls and placed 2.0 – 4.0 m apart and equidistant from the seated listener. Turning the loudspeakers slightly inwards will sharpen the stereo image at the expense of a narrower sound stage.

Concept 90

The Concept 90 loudspeaker should be positioned at least 0.2m from a back wall and central to a TV screen.

Connections

Terminals and Connectors

The Concept Series are bi-wireable. A bi-wireable crossover has four terminals. The upper pair of terminals connect to the treble (HF) speaker and the lower pair to the bass (LF) speaker. The crossovers are pre-fitted with removable links to connect the terminal pairs and configure the loudspeaker in single-wire mode. This allows you to connect the loudspeaker conventionally using one pair of cables.

Standard Connections

Connect the RED (+) terminal of the RIGHT loudspeaker to the RED, Positive (+) terminal on the RIGHT channel of the amplifier.

Connect the BLACK (-) terminal of the loudspeaker to the matching BLACK, Negative (-) terminal of the amplifier.

Repeat this procedure for the LEFT channel.

Bi-Wire Connections

To bi-wire: Prepare two twin cables for each loudspeaker. Unscrew all the loudspeaker terminals and remove both links. Now connect the treble terminals and the bass terminals to the amplifier following the procedure described in standard connections.

Standard Connections

Bi-Wire Connections

Running In

In common with many types of complex mechanical systems the Concept loudspeakers will not deliver their optimum performance until they have been in use for a certain initial running-in period. The correct performance of a loudspeaker depends in part on the compliance of the suspension materials used during manufacture and these will only attain their long term steady state once they are operating at the temperature and modulus of elasticity specified during the design phase. It can take several days for a loudspeaker which has been stored in a cold warehouse to finally reach room temperature and so we recommend at least 24 hours of normal use for the drive units to loosen up sufficiently for them to perform as the designer intended.

Aftercare

Cabinet Care

Clean cabinets only with a lightly dampened cloth. Do not use solvent based cleaning materials. Never use abrasives of any kind.

The cabinet surfaces will usually only require light dusting. Should an aerosol or other cleaner be used, apply the cleaner onto the cloth first and not directly onto the product. Test a small area first, as some cleaning products may damage the finish. Avoid products that are abrasive, or contain acid or alkaline agents. Do not use any cleaning materials on the drive units and avoid touching them as damage may result.

Grilles

Grilles should only be cleaned using a soft brush when necessary.

If using the loudspeakers with the grilles removed, remember to replace them if pets or children are present.

Drive Units

Do not touch the drive units as they are easily damaged when exposed.

Warranty
