Installation Guide
1. Unpacking
Please follow the diagrams to unpack your Performance loudspeakers. Two people will be required to lift each loudspeaker from the
box. Gloves are included for your convenience.
2. Floor Spikes
Fitting the supplied, custom-designed Performance floor spikes will drastically improve bass response and overall imaging. To add
the spikes, carefully lay the speaker on its side and screw the spikes into the indicated positions. Adjust the height, making sure the
speaker is stable, and then tighten the locknuts. Now press firmly down on the speaker top to ensure it is properly grounded to the
floor. If you are concerned about marking your floor, place a coin under each spike.
3. Cabling
As a guideline you should budget at least 10% of the cost of your loudspeakers on the necessary cabling. Performance
loudspeakers have the capability for single and bi- wiring while the Performance 6 also offers tri-wiring. The loudspeakers can also
be bi-amplified while the Performance 6 can be tri-amplified. This can also be achieved with the use of mono-blocks.
4. Positioning
As a starting point, form a triangle between the listener and the pair of loudspeakers where all sides of the triangle are of the same
length. Adjust the speaker and listener positions until you are happy with the sound. Adjusting the layout of your listening room will
also give great improvements to the acoustics.
Note: You will probably adjust the starting position during listening tests.
To Improve
Bass
(Frequency 20Hz~500Hz,
Wavelength 17m ~ 0.7m)
Mid-Band
(Frequency 500Hz ~ 5kHz,
Wavelength 0.7m ~ 70mm)
Treble
(Frequency 5kHz - 30kHz,
Wavelength 70mm ~ 17mm)
Please bear in mind that adjusting one element of the listening environment will affect another. For example, increasing the
absorption for controlling the treble may make the mid-band or bass more noticeable. Remember to adjust only a little at a time and
to make only one change between listening tests.
Performance makes use of self-cancelling magnets. To avoid problems with stray flux the loudspeakers should be positioned at least
10cm away from equipment sensitive to magnet fields such as CRT televisions.
5. Running In
It is important to allow your loudspeakers a running-in period of at least 100 hours. This allows the various materials to reach their
correct properties. Place your speakers facing each other, reverse the polarity on one speaker and play music, or preferably, a
special running-in signal through them. The audible output of the speakers is significantly reduced in this configuration thus enabling
use of a higher level signal.

Suggestion
Adjust distance between speakers and wall.
Adjust listening position forwards and backwards.
Adjust position of large objects in the room starting at rear wall
Adjust distance between speakers and side walls.
Adjust angle of speakers.
Adjust position of objects located by side walls.
Adjust amount of soft fabrics/hard surfaces etc. in room, starting with those nearest the
speakers.
Adjust vertical angle of speakers by adjusting spikes.
