Boxer The boxer breed originated in germany in the late 19th century and was brought to the us after World War I. Today, boxers are a part of the akcs working dog group. Dont be fooled by that "worried" look on a boxers face. Boxers are known for their fun–loving, genial, and at times downright clown–like demeanor, as well as their remarkable rapport with children. However, boxers are equally known for courage in the face of danger, or threat to family or loved ones. The boxers innate intelligence, combined with its natural strength of stature, makes it a breed beloved by many. Solid 1.25% silver conductors Solid conductors eliminate strand–interaction distortion and reduce jitter. Solid silver–plated conductors are excellent for very high–frequency applications. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high–purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high–quality subwoofer cables. Polyethylene air–tube insulation Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. All of boxers conductors use pe air–tube insulation because air absorbs next to no energy, and polyethylene is low–loss and has a benign distortion profile. Pe air–tube insulation causes much less of the out–of–focus effect common to other materials.
