Quantum 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.
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 (Quantum 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.
MAGNAT QUANTUM LOUDSPEAKERS AS A FRONT OR REAR LOUDSPEAKER
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)
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 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. 5a), bi-wiring (Fig. 5b) and bi-amping (Fig. 5c).
MAGNAT QUANTUM CENTER 72
The QUANTUM CENTER 72 loudspeaker visually and acoustically ideally matches the other
QUANTUM 720 models. The loudspeaker is placed immediately on or under the television set. Otherwise
please adhere to the general recommendations outlined in the previous chapters.
MAGNAT QUANTUM 7230A
The QUANTUM 7230A active subwoofer visually and acoustically ideally matches the other loudspeakers
in the QUANTUM 720 series. Please refer to the separate operating instructions supplied with this
product.
CONNECTING TO AN AV RECEIVER
Figs. 6 and 7 show two different methods of connecting to AV receivers.

HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All MAGNAT loudspeakers are designed and built for optimum sound reproduction with the tone controls
in the central position – i.e. with “linear” amplifier output. Turning up the bass and treble controls too far
delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the
speaker units!
