8.1 Connection

If the 

axent

 or 

axess

 are to be used with Naim amplification, 

Naim loudspeaker cable will produce the best results and is 
necessary with some amplifiers. Cable length should be between 
3.5 metres and 20 metres (11.5ft and 66ft). Your local retailer 
will be able to make up cables of the appropriate length.

Connect the loudspeaker cables with their custom Naim plugs to 
the input sockets located on the rear of the enclosure. Ensure 
that the positive plug - identified by a rib on the side of the 
cable and a tag marked “pos” on the side of the connector body 
- is inserted to the red input socket.

8.2 Tweeter Adjustment

The 

tweeter 

is mounted on an adjustable suspension plate. It 

is important both that the tweeter “bounces” freely on the plate 
and that it is held in line with the front panel of the enclosure.

If the tweeter does not bounce or it is not held in the correct 
position (i.e. the plate appears bent), the plate can be adjusted. 
Carefully remove, one at a time, the appropriate fixing screws 
and gently bend the appropriate arm or arms of the plate to 
correct the bend. Replace the screws, tightened as lightly as 
possible to ensure security, and re-test the “bounce”. Repeat 
the exercise if necessary. Diagram 8.3 opposite illustrates the 
tweeter suspension plate correctly and incorrectly adjusted.

8 Introduction and Installation

Naim loudspeakers are precision acoustic instruments that will only achieve optimal 
performance if installed and set up carefully. Please read these instructions before 
installing and using the loudspeakers. Please also retain the packaging for future 
use.

The performance of any loudspeaker will be influenced by the room in which it is located and 
even small changes of loudspeaker position can significantly influence the sound. Alignment with 
the listening position and proximity to room boundaries will in particular influence the subjective 
performance. The position of a centre channel loudspeaker tends to be influenced by the type 
and location of the associated video screen. However, the influence of the room boundaries and 
alignment to the listening position should still be taken into account.

The 

axent

 and 

axess

 are designed to reproduce full bandwidth, full power signals and are intended 

to be positioned centrally just below the screen. If the location of the loudspeaker results in too 
much bass some adjustment of low frequency equalisation via the AV processor may be necessary. 

Best results from 

axent

 and 

axess

 are likely to be gained if they are directly coupled to the floor via 

a rigid, spiked stand. Both speakers are equipped with spike location pads on the underside to help 
enable such mounting. If however the screen stand is also to carry the speaker it is advisable to at 
least decouple the screen, perhaps with compliant pads, so that vibration from the speaker does not 
disturb the picture.

The 

axent

 and 

axess

 are magnetically shielded. However, the extreme sensitivity of some CRT tubes 

to low levels of magnetic flux may mean that, in rare cases, the shielding may not be sufficient. 
Should your screen suffer picture distortion caused by the proximity of a centre speaker contact your 
dealer or installer for advice.

Loudspeakers, like many hi-fi components, will take time to stabilise and “run-in” and can be 
expected to improve with use even over a period of weeks. For this reason it is prudent not to finalise 

axent

 and 

axess 

positioning until they have been operating for at least one week.
