To make the most of your Coltrane Supreme loudspeaker system, please consider the
following suggestions:
The impact loudspeaker cables can have on the sound is dramatic. Be sure to use the
same brand, type, and length of cable on each channel. Mixing different types and/or
lengths of cable can upset the precise timing and balance of your loudspeaker.
We recommend the use of Jorma Design Prime cable to achieve maximum result. It is
the same as the loudspeaker’s internal wiring.
The Coltrane Supreme loudspeaker system are designed with bi-wiring in mind.
If you prefer bi-amping, we recommend that you use the same type of cable for best
sound reproduction. For single-wire applications, please use the enclosed jumpers.
At the back of your Supreme loudspeaker, you will find four pairs of heavy duty
terminals that will accept any standard connection. Whatever type of connection you
use, make sure that the contact is tight, and has a proper contact area. Tighten the
posts, and then retighten after a few days to make sure that the connections haven’t
loosened.
Always turn off the power of your entire system before making connections to your
speakers. We recommend using an amplifier with sufficient power (typically a minimum
of 30 watts).
In order to obtain the best localization of instruments and voices, as well as the
deepest, most natural bass, it is important to connect your loudspeakers in phase
(which means that the drivers are moving in and out in the same direction and at the
same time). The connectors on the speakers are clearly marked, and those on your
amplifier and speakers cables should be also be marked. Keep all markings consistent
in order to ensure in-phase connections.
The higher the quality of a loudspeaker system, the more demanding it will be
regarding burn-in time. Your newly unpacked Coltrane Supreme loudspeaker system
need quite a bit of playing time to reach their optimum performance capability.
We have enclosed a CD to help speed up this process. Please allow the CD to be run
for a minimum of 24 hours before attempting to adjust the placement of the
loudspeakers in your listening room. Due to the high-tech materials used in the drivers,
the Coltrane Supreme will sound a bit harsh in the beginning, but after 50 hours of
playing your loudspeakers will sound good.
After about 200 hours of playing, your system will be optimized. The sound will be
more open and detailed, and display more natural musical warmth.
Compare the process to that of a fine musical instrument, which has to be played for a
period of time before reaching its full musical potential.
