AudioQuest Gibraltar full range spk 8 ft pr BFAS

Available - Two pairs of AudioQuest Gibraltar full range speaker cable for sale, both identical and are 8 ft runs with BFAS on both ends.  (I used these for a full bi-wire set up with one pair for low end drivers and one pair for high end drivers on my main speakers.)  
Excellent condition, essentially like new, with original box and packaging, owners manual and polishing cloth included.     
Note - Price listed is per pair.

SOLID
PERFECT-SURFACE COPPER+ (PSC+) CONDUCTORS: Solid conductors prevent strand interaction, a major
source of cable distortion. Extremely high-purity Perfect-Surface Copper+
minimizes distortion caused by grain boundaries that exist within any metal
conductor, nearly eliminating harshness and greatly increasing clarity
compared to OFHC, OCC, 8N and other coppers. 



CARBON-BASED NOISE-DISSIPATION (INSULATION): The negative conductors in Gibraltar are insulated with
partially conductive Carbon-Loaded Polyethylene. This remarkable material
damps radio-frequency garbage from being fed back into the amplifier. The
sonic benefit is exactly the same reduction in “hash” and better
dimensionality that comes whenever RF garbage is reduced in an audio circuit.
Gibraltar uses Foamed-Polyethylene Insulation on its positive conductors
because air absorbs next to no energy, and Polyethylene is low-loss and has a
benign distortion profile. Thanks to all the air in Foamed-PE, it causes much
less of the out-of-focus effect common to other materials. 



DIELECTRIC-BIAS
SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1): All insulation slows down the signal on the conductor
inside. When insulation is unbiased, it slows down parts of the signal
differently, a big problem for very time-sensitive multi-octave audio.
AudioQuest’s DBS creates a strong, stable electrostatic field which saturates
and polarizes (organizes) the molecules of the insulation. This minimizes
both energy storage in the insulation and the multiple nonlinear time-delays
that occur. Sound appears from a surprisingly black background with
unexpected detail and dynamic contrast. The DBS battery packs will last for
years. A test button and LED allow for the occasional battery check. 



DOUBLE STAR-QUAD
GEOMETRY: The relationship between conductors defines
a cable’s most basic electrical values (capacitance and inductance). However,
even when those variables are kept in a reasonable balance, the relationship
between conductors can be varied in ways that greatly affect the sound. The
Double Star-Quad construction of Gibraltar allows for significantly better
dynamic contrast and information intelligibility than if the same conductors
were run in parallel. 



SPREAD-SPECTRUM
TECHNOLOGY (SST): Any single size or shape
of conductor has a specific distortion profile. Even though radially
symmetrical conductors (solid or tubular) have the fewest discontinuities,
any conductor of a particular size does have a sonic signature. SST is a
method for significantly reducing the awareness of these character flaws by
using a precise combination of different size conductors. The different
SST-determined conductor sizes used in Gibraltar allow an exceptionally
clear, clean and dynamic sound. 



BIWIRING: Gibraltar is an exceptional Single-BiWire cable. When
the halves are separated at the speaker end, the Double Star-Quad Geometry
turns Gibraltar into a true Double-BiWire set thanks to the magnetic autonomy
of each Quad-conductor section. On its own, one Star-Quad conductor group
would be a little lightweight in performance as it is biased towards treble
finesse. The other Star-Quad conductor group is biased toward the bass; it’s
more forceful and lacking ultimate resolution. Together they form a
completely optimized full-range design. When separated, the Double Star-Quad
design allows Gibraltar to be a maximum-performance Double BiWire in a single
cable. 



TERMINATIONS: AudioQuest offers a wide range of high-quality
connectors that allow Gibraltar to be securely attached to any type of
equipment. Quality is in the low-distortion sound, not necessarily in the
eye-candy effect. AQ ends are either dull looking gold or silver because
these metals are plated directly over the connector. There is no shiny and
harsh sounding nickel layer underneath. AQ PK-spade lugs are soft because
better metal is soft, and facilitates a higher quality connection. For pieces
requiring a banana plug or BFA connector the AQ PK-BFA/Banana provides
unprecedented performance over conventional brass versions. 



APPLICATION: The metal breakouts on either end of Gibraltar are
marked “Speaker End” or “Amp End.” Please use cables in the direction
required.
