There should be a clear line of sight between the loudspeakers and the listening position. Any sound-
absorbing or reflecting obstacles in the path will distort the sound. When you install the loudspeakers
the following distances should be maintained:
floorstanders: at least 20 cm away from the rear wall and at least 30 cm from the side walls. This will
prevent excessive emphasis of the bass range.
Bookshelf speakers: shelf loudspeakers should also be as free-standing as possible, the distance to the
sides and rear to walls and items should be at least 10 cm, the tweeters should be located at ear height.
Spikes (floorstanders): you should use the supplied spikes when setting the speakers up. This isolates
them from the supporting surface, preventing unpleasant resonance effects. You can choose between
metal and hard rubber spikes for the standing speakers. The spikes are screwed into the threaded
bushes on the bottom of the speaker.

The front loudspeakers are positioned at ear height on the left and right as equidistant from the television
as possible. The rear loudspeakers are placed at ear height or a little above on the left and right besides
or better behind the listening position. (Fig. 4)

The connector panels on the ELEMENTA speakers are equipped with 5 terminal screws, enabling
bi-wiring/bi-amping in addition to conventional connection to an amplifier. The upper terminals are
connected to the treble and mid-treble side of the crossover and the lower terminals to the bass side.
An additional connector terminal enables a 2dB treble boost option.
Bi-wiring means using separate cables to carry the high and low audio frequencies. Bi-amping takes this
idea one step further and uses separate power amplifiers as well as separate cables for high and low
frequencies. Bi-amping in particular produces an additional improvement in sound reproduction quality.
For conventional connections, metal bridges are installed as standard to make the +2dB treble
adjustment active. The bridge can be switched to the linear setting by unscrewing the corresponding
terminals. (Fig.5)
The terminals have to be removed for bi-wiring and bi-amping mode. Fig. 6 and fig. 7 show the
connection to the amplifier(s).
The right treble setting depends on the room, the positioning of the speakers and, of course, personal
taste. The +2dB setting is recommended for rooms with heavy upholstered furniture and curtains, for
example, which have a muffling effect.

Bi-wiring means using separate cables to carry the high and low audio frequencies. Bi-amping takes this
idea one step further and uses separate power amplifiers as well as separate cables for high and low
frequencies. Bi-amping in particular produces an additional improvement in sound reproduction quality.
The special connection terminals of the ELEMENTA loudspeakers support both conventional connection
and operation in bi-wiring and bi-amping modes. There are four screw terminals on each speaker.
The top pair are for the tweeter (high frequencies), the lower pair for the woofer (low frequencies). The
factory-installed metal strips connecting the positive and negative terminals are for conventional 2-wire
connection and must be removed for bi-wiring and bi-amping operation. The pictures below show the
correct set-up for conventional operation (Fig. 8a), bi-wiring (Fig. 8b) and bi-amping (Fig. 8c).
