Positioning is important
It really does pay to experiment with the positioning of your Obbligatos. The difference
between “acceptable” and “fantastic” audio reproduction is often only a question of a
few simple adjustments to the room’s acoustics, and to the positioning of the
loudspeakers.
In general, loudspeakers should be positioned so that the tweeter drive units are
approximately at ear level when you are seated in your favorite listening position. The
distance between the two loudspeakers should be approximately 80% of the distance
between the loudspeakers and the listening position. The loudspeakers may be turned
slightly inwards. This will give better focus and precision to the audio signals in the
center of the stereo image.
The Obbligato S (stand version) should be mounted on a mass loaded stand. We
suggest the matching Angstrom US-24NC stand.
Ad usting the bass level
These loudspeakers perform best when they are placed somewhere between 80 cm
and 150 cm from the nearest wall. It is also important to remember that loudspeakers
should be allowed to radiate the sound, without hindrance, through the air and towards
your listening position. Therefore, upholstered furniture and similar objects should
never be placed immediately in front of the loudspeakers or in front of the side firing
woofers as this will damp the treble and upper mid-range, muddy the low frequencies
and will render the sound inarticulate. The stereo image will lose its precision.
Some listening rooms are plagued by problems of ‘standing waves’ which cause a
rumbling, distorted low bass response. In this case the Obbligatos should be placed a
good distance (up to 2 metres, 6 feet) away from the end and side walls, s that the
omnidirectional low frequencies are able to be radiated unhindered. By following this
procedure, the bass level is reduced by a few decibels but the output is controlled. The
bass response will be tighter and more dynamic. Experiment, your listening room is the
most important part of the listening puzzle.
The addition of two Angstrom Profondos or two Angstrom Forzas, low frequency
transducers will complete your audio system. The addition of only one of our low
frequency transducers will transform your audio experience from just fantastic to truly
“unbelievable”. Two will bring realism to new heights.
Spikes
Your Obbligato F (floor version) has been fitted with brass inserts, brass carpet spikes
and brass wafers for use on hard floor surfaces.. If you place the Obbligato F on carpet,
we recommend that you replace the brass wafers with the supplied brass carpet spikes.
