UNPACKING
Unpack your speakers with care so as not to damage the natural
wood finish. Keep all the packaging materials, in case you ever
need to ship them again.
AMPLIFIER REQUIREMENTS
It’s a well known fact in HiFi that more damage is caused to
loudspeakers by using under-powered amplifiers “clipping” at
high output levels, than almost any other cause. Compared to
a normal audio signal which has smooth sine-curve waveforms,
clipping creates a “sharp” or “cut-off” shaped waveform which
may cause heat build-up in the loudspeaker’s coil assembly,
leading to damaged and burnt out drive units.
It really is preferable to carefully use an amplifier of 100 watts
rated output to drive a 75-80 watt rated loudspeaker, than to
use a 50 watts rated amplifier at maximum volume.
The output of most recent amplifiers is quoted into a nominal 8
ohm loudspeaker load. A few (e.g. older Valve [Tube] Amplifiers)
may have selectable output positions for use with either 4, 8 or
16 ohms loudspeakers. In this case select the 16ohms output.
Because the “Classic” LS3/5a has low sensitivity and a nominal
15 ohms impedance, if not using a Valve [Tube] based amplifier
rated at 25 watts or more into 16 ohms, we recommend using
an amplifier with at least 60 watts output into 8 ohms. This way
it is unlikely that the full power setting will be required and this
should therefore avoid such clipping damage.
POSITIONING
Correctly setting up and positioning your Falcon Acoustics
LS3/5a’s is important.
They should be placed on stands and “toed-in” towards the
listening position slightly.
Most users find 600mm (24”) stands to be the optimum stand
height.
Please note that placing them into a comer will generally make
bass output more “boomy”. However, positioning them away
from walls will give the best results. Furniture and wall coverings
also make a considerable difference. We recommend you
experiment until the best results in your room are obtained.
