Loudspeaker placement

Amphion products are more directive than traditional speakers and therefore the positioning in the listening room is an

easy task. They can be placed on a bookshelf, mounted to the wall or ceiling by brackets or placed on speaker stands.

Due to higher directivity speakers interact with the room less and reflections from ceiling, floor and walls are easier to

control than with traditional speakers usually and therefore first class sound quality can be achieved even in acoustically

challenging listening rooms.

The best sound quality is achieved when the speakers are placed far enough ( minimum 60 cm/2 ft ) from the walls and

corners of the room. Optimally the acoustical centre point of speaker is vertically at the same level with ears. Acoustical

centre point of speaker is in the middle of the waveguide and bass unit and thus in the midpoint of the speaker itself. If the

speakers are placed up to the wall or near to ceiling they should be tilted towards the listener so the line from the acoustical

centre point is pointed towards the ear.

The speakers should be positioned so that they are located at equal distance from listener and the distance between

speakers is approximate the same as distance from speakers to listener ( picture 2 ). The speakers can be placed so that they

are facing directly onwards, or they can be turned slightly towards the listener ( picture 2 ). In most cases the best result is

achieved by turning the speakers so that horizontal axis goes slightly outside of shoulders. Adjustment of horizontal axis

works as certain kind of treble level adjustment. Aiming speakers directly towards the listener to increases the treble level

and respectively turning speakers away from listener decreases the treble. Every listening room has its unique shape, volume,

materials and decoration, which all shape the acoustical properties of the room. Therefore the placement instruction can

act as a rough guideline only and optimal positioning is found solely experimenting and listening.

Mounting to a stand and wall bracket

Mount the speakers to the stand or to wall bracket always according to the instructions of the manufacturer. Speakers

can be attached to stands by using adhesive tape, blue-tack or screws. Wall- and ceiling brackets must be mounted by

following the instructions provided with the mounts. If you use screws, make sure that they are meant for MDF- board and

can handle the weight of the product. When drilling the holes for screws take care not to drill the holes through the wall

of speaker. Wall thickness is 19 mm ( 3/4").

Connecting to ampliﬁer

CAUTION ! Always make sure that the ampliﬁer is switched oﬀ before making any connections

with loudspeaker cables or interconnects.

The speakers are connected to the ampliﬁer via the connectors at the backside of speaker and by speaker cable. Right

speaker is connected to the right channel of ampliﬁer and left speaker to the left channel of ampliﬁer. Similarly the rear

speakers and centre speakers are connected to their respective channels. Spade lugs banana jacks are the most commonly

used connectors. Non-terminated cables can also be connected directly by stripping the insulation oﬀ the end of the

wire for about 10 mm ( 1/2") and setting the stripped plain wire into the speaker connector hole. Turn the connector top

open so that the hole aside the connector base can be seen. Set the plain wire into the hole and tighten the connector.

Do not use any tools for tightening to avoid damaging of connector. Connector which is market with black is ( - ) and red

connector is ( + ). Always connect ( + ) marked wire to ( + ) connector of ampliﬁer and ( - ) marked wire to ( - ) connector

of ampliﬁer.

NOTE! Note that ( + ) and ( - ) connectors, plain wires or cords does not touch each other at any situation – this can cause

damage to the ampliﬁer. Tighten the connectors carefully to avoid the cables from loosening and causing a short circuiting

of the ampliﬁer. Always read the ampliﬁer manual before make any connections.

Blocking the rexlex tube / venting hole

The speakers are delivered with foam plugs for blocking the reﬂex tubes / venting holes of the speakers if necessary.

The blocking of venting holes is recommended if the speakers are placed near the wall and/or the bass reproduction

is elevated. If the Amphion Impact– series subwoofer is used with the speakers the blocking of venting holes is always

recommended.
