Your dealer is responsible for making sure that the system sounds exactly as it should and information given here is not intended to reduce this responsibility in any way. 1 2 2 3 2 Cables and Connections Please do not modify the standard interconnect cables supplied with your Naim equipment. [. . . ] The distance between the speakers and the rear wall is the aspect of positioning most likely to require adjustment as you become familiar with the characteristics of the loudspeakers in your room. 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 loudspeaker positioning until the system has been operating for at least one week. Now lift the Lower Cabinet, together with its foam endcaps out of the carton. Stand it on the floor, plinth lowermost, and remove the top foam end-cap. Now move each Lower Cabinet with the Tweeter Suspension Assembly attached into the appropriate position. Take care not to place them so close to the wall that the rear spikes foul any carpet gripper that may be fitted. Also leave some space for final adjustment of the Tweeter Suspension Assembly and for the connecting cables. Adjust the spikes so that the cabinets are upright (a small spirit level will help) and do not rock. Check again, once the lockTweeter Suspension nuts are tightened, that the Assembly cabinets do not rock on the spikes. Note: With thick carpet and underlay it can be difficult to ensure that the spikes are resting on the floor. Small slits cut into the carpet once the loudspeaker position is finalised will help. Pin Spacer 6. 4 SL2 Assembly Fit a Pin and a Spacer to the three holes in the aluminium top surface of each Lower Cabinet. There are two holes at the front and one at the back. Stage 3 The pack containing this manual also contains Cabinet Interface Pins and Cabinet Spacers. Fit a Pin and a Spacer to the three holes in the aluminium top surface of each Lower Cabinet. See Diagram 6. 4 Tweeter Adjustment Panel Upper Cabinet 6. 5 SL2 Assembly Take each Upper Cabinet in turn and carefully lower it onto the appropriate Lower Cabinet locating the Pins in the corresponding holes on its underside. At the same time as each Upper Cabinet is lowered onto each Lower Cabinet, the tweeter must be inserted through the back and front apertures of the Upper Cabinet. Now take each Upper Cabinet in turn and carefully lower it onto the appropriate Lower Cabinet locating the Pins in the corresponding holes on its underside. At the same time as each Upper Cabinet is lowered onto each Lower Cabinet, the tweeters must be inserted through the apertures of the Upper Cabinets. The loose fit of the Pins allows some adjustment of the alignment of the two cabinets. See Diagram 6. 5 5 SL2 Assembling and Installing SL2 (continued) It is vitally important for correct operation of SL2 that the Upper Cabinets are located properly on the Lower Cabinets, that the Pins are in place and that the two cabinets only touch via the spacers. The alignment of the Tweeter within the Upper Cabinets can be adjusted via either the two bolts connecting the Tweeter Suspension Assembly to the Plinth or the four screws that attach the Tweeter Adjustment Panel around the front face of the Tweeter. If the four adjustment panel bolts are loosened they should be re-tightened as securely as possible. As well as being adjusted to sit centrally when viewed from the front, and flush with the front panel, the Tweeter must oscillate freely without touching any part of either cabinet. Finally fit a Grille to each SL2 by aligning it with the top of the Lower Cabinet before pushing it gently against the fixing tape on the Upper Cabinet. [. . . ] Finally connect the amplifier output speaker cables with their custom Naim plugs to the input sockets on the back of the passive crossover units. Ensure that each 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 sockets. Intro 2 Connect the loudspeaker cables with their custom Naim plugs to the input sockets located on the rear of the Lower Cabinet. Ensure that each 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 sockets. 7. 3 Speaker Components Upper Cabinet Lower Cabinet PIP 8 axent, axess 8 Introduction and Positioning Naim loudspeakers are precision acoustic instruments that will only achieve optimal performance if installed and set up carefully.
