Supra Quadrax 4 x 2 mm² on 100 meter bobbin - Loudspeaker Cable with Emphasis

Really affordable High-End Loudspeaker Cable featuring Tube Conductors of 4 x 2.0 mm² at such a price it is nothin less than a bargain.

The tube conductor design means that 120 individually tin plated strands in a braid forms a tube around a PP plastic core. It forces the music signal to meet the same crossection area irrespective of frequency. The higher frequency, the further out in the conductor perimeter the law of physics forces the signal, hence resulting in unequal conductivity properties for the various frequencies. If adressed in the cable design with tube formed leads we manage the differencies efficiently allowing for a flat frequency response, ultra-fast transients and transparency. If configured in a Star Quad conductor formation (single wire/full range) RFI pickup and outgoing magnetic fields (lowered induktance) are almost completely cancelled out, thanks to the symmetry of current in the opposite conductor pairs. Finally the strand tin plating will counteract any current jumps tendencies between the strands thus creating a diode effect followed by corresponding phase shift.

In addition to the malignant inductance affecting any power transmissions with high current transients, we have also gained a lowered capacitance. The capacitance is considered less malignant in speaker circuitry, but if possible it should also kept as low as possible since it also contributes to a treble roll-off and phase shift. The special PolyPropylene (PP) insulation and conductor core is chemically and physically extremely stable and features low capacitance.

What will you experience? We think that you will have a dynamic explosion, especially if you own a powerful amplifier and larger pair of speakers. The vast majority who tested this cable, sum up its properties as very dynamic and expressions like "this is really rock'n'roll" is not unusual. And this is off course both flattering and awaited, since we designed it to be an alternative high-end cable, for those how wanted a more straight forward sounding, but still remain faithfull to the very fabric of Supra Cables no-nonsense concept.
