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:
Quantum floorstanding speakers: 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.
Quantum 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: 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, while the
enclosed hard rubber spikes are used for the shelf and centre speakers. The spikes are
screwed into the threaded bushes on the bottom of the speaker.
MAGNAT QUANTUM 600 LOUDSPEAKERS AS A FRONT OR REAR LOUD-
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. 3)
Quantum 603: if possible, the cross-over frequency for the front and rear channels
should be adjusted to approximately 80 Hz in the AV receiver's set-up. Otherwise all the
recommendations made in the previous chapter also apply.
MAGNAT QUANTUM 607, 605 AND 603 – BI-WIRING AND BI-AMPING
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 Quantum 600 loudspeakers support both
conventional connection and operation in bi-wiring and bi-amping modes. There are four
screw terminals on each speaker. The inner pair are for the tweeter (high frequencies),
the outer pair for the woofer (low frequencies). The factory-installed cables 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. 4a), bi-wiring (Fig. 4b) and bi-amping
(Fig. 4c).
