SPEAKER CABLES

***(Read AVSA April 2017 review of this speaker cable)***

“The Progeny is the entry level speaker cable in the Neutralis speaker cable line up. Yet significantly, the design philosophy and the standards in manufacturing that are part of the top-line product (The Proto) are maintained. As a result it is a superb sounding, reference grade product competing with products way past its price point."

Objective

Designed to have minimal influence on the transmission of the audio signal. Totally handmade; from the first step of polishing the high purity copper conductors to finished product. Can be made to specified lengths.

Low inductance.

The Progeny Speaker Cables take into account the specific parameters necessary in speaker cable design, namely inductance and dielectric absorption. The Progeny Speaker Cables have very low inductance due to the geometry employed which allows inductive coupling to occur. Considering the very low inductance figures of The Progeny Speaker Cables the capacitive load is limited due to the geometry and air dielectric philosophy, allowing it to work well with amplifiers that may be unstable with highly capacitive loads.

Minimal skin-effect

Skin-effect occurs since the high-frequency currents tend to flow on the outer "skin" of the conductors whereas lower frequencies are more uniform in current distribution across the conductor cross-section. Correct gauge of conductors result in all frequencies flowing more evenly in the conductors, thus minimising skin-effect. Neutralis carefully selects conductor gauge to facilitate optimum frequency response across the spectrum.

Minimal use of form hugging conductor insulation

Form hugging insulation or coatings on conductors are undesirable. The dielectric material stores conductor energy as a type of charge in the same manner as capacitors retain part of the charge even after being discharged. The remaining charge in the dielectric material may be released when it is not desired. This is known as Dielectric Absorption or voltage retention. The higher the dielectric constant of the insulation the more pronounced the problem is. This is detrimental since the latent charge can lead to variance in the amount of energy required to charge the dielectric. Remaining charge can dissipate onto conductors at the incorrect time leading to "smearing" of the audio signal. The Progeny like the larger models limits form hugging conductor insulation in the design. This leads to improving both high and low-frequency micro resolution, focus,dynamics and neutrality.
