Product Description

Black Rhodium Polka is a no-compromise loudspeaker cable engineered for the greatest reduction in distortion in those areas where the Black Rhodium’s distortion-busting technology has the greatest effect.

Polka efficiently removes the effects of RFI interference and micro-vibrations within the cable. Conductors in Polka are beneath than 4mm squared in cross section to grant superior control to the amplifier over loudspeaker cone movements. This also delivers a more punchy bass that is needed for high power systems and those with extended low frequency response.

Anti RFI screening

Polka is fitted with a tightly braided metal screen to lower distortion effects of high frequency interference, combined with the RFI filter found in the Quickstep and Foxtrot speaker cables, Polka is twisted along its length to limit RFI and shield the signal wires from RFI generated from Radio, Wifi, Mobile Phones and even central heating systems.

Low Transient Phase Distortion

Polka grants a clear diction of a singer’s voice and isolates musical instruments well through a dramatic reduction of ‘Transient Phase Distortion’. This is reduced by using thicker insulation than is usual in speaker cables, increasing the distance between conductors and thereby reducing the magnetic field seen in each conductor wire as a result of the magnetic field created by the current in the other conductor wire. A further increase in the distance is achieved via attractive cable braid lowering ‘Proximity Effect’ distortion. The music becomes clearer and more dynamic, with greater ambience and emotion.

Mechanical Vibration Damping

Polka construction includes the use of two separate and complementary materials that effectively damp Mechanical Vibrations within the cable without the expense of Vibration Stabilisers.

Rhodium Plated Locking Connectors

Polka speaker cables are terminated with Black Rhodium Locking rhodium plated plugs. The plating preserves a purer and less corroded contact between the plug and socket and the effect is a much livelier and more exciting sound. Extra security of the link between the plug and terminal is achieved by rotating the screw cover to the plug for an ultra strong connection that is not simply removed by force. Polka is hand built at the Black Rhodium factory using chosen components and materials with a proven record for sound quality enhancement as demonstrated in Black Rhodium’s range of high end cables.
