Harmonic Technology's Pro-9 Reference
(available as a mono speaker wire, internal bi-wire or external bi-wire) is
an improvement of our award-winning Pro-9 Plus speaker cable. In a variety of
lengths and terminations, the Pro-9 Reference will accommodate any of your
speaker cable needs.
The Pro-9 Reference
is our finest copper speaker cable. It uses the highest quality materials and
our unique Balanced Field Geometry to ensure the best signal transfer and
greatly reduces inductance and capacitance for extremely accurate sound.
Manufactured with 9 AWG wire that consists of the highest purity 6N copper
available (99.9997%) and our world-renowned Single Crystal design, this
speaker cable virtually eliminates all distortion and coloration. In
addition, the Pro-9 Reference uses air-tube technology to separate the
conductors within the cable to dispense with any potential cross-talk.
Harmonic Technology's Pro-9 Reference is the best speaker cable available for
large speakers and/or exceptionally powerful amplifiers.
The Pro-9 Reference
allows the bass to be very tight, yet extremely dynamic. The midrange is
exceptionally rich, with tremendous detail and harmonic completeness that
borders on realism. The highs are very smooth and detailed, without the
artificial "zing" that you may have experienced with other speaker
cables. Harmonic Technology has delivered a speaker cable that allows the
soundstage to bloom as large as your room—a holographic depth and
roundness you simply must experience. The Pro-9 Reference will easily
outperform your existing speaker cables and transform the very sound of your
system.
Internal or
External Bi-Wire
We have developed two distinct types of the Pro-9 Reference bi-wire speaker
cable—an internal and an external version—in order to accommodate
your varying needs and configurations. The Pro-9 Internal Bi-Wire is
similar to our previous Pro-9 Plus speaker cable, but it contains a separate
woofer set and tweeter set within one jacket. The configuration consists of two
spades at the amp end and four spades at the speaker end. The Pro-9 Reference
Internal Bi-Wire is ideal for customers who prefer only one single jacket for
each side of the speaker.
The Pro-9
Reference External Bi-Wire provides a unique design, where we have merged
two separate sets—the woofer set in the inner circle and the tweeter
set in the outer circle—at the amp end. This type of configuration is
ideal for situations where your speaker has a larger than average distance
between the woofer binding post and the tweeter binding post. The
configuration consists of two spades at the amp end as well as a spade on the
woofer binding post and a locking banana on the tweeter binding post. The bonus of this configuration is
that if you move from a bi-wireable speaker to a speaker with only one pair
of binding posts is that you don’t have to change your speaker cable. You can use the spades and bananas
from each cable to the same binding post to give you a very high caliber mono
wire.
