Jorma Prime Bi-wire 1m is a premium speaker cable designed for maximum transparency and control in high-end stereo and multi-channel systems. It is intended for users who use bi-wire connection and are looking for a stable signal transmission between the amplifier and speakers with minimal losses.
Technical characteristics
Category: passive speaker cable, bi-wire configuration (two separate branches to the speaker)
Length: 1 m
Conductors: high purity copper, special geometry for reduced inductance and capacitance
Dielectric: low loss (PTFE/PE type), multilayer insulation
Shield: mechanical/electrostatic noise control without classic "heavy" shield (optimized for speaker currents)
Termination: factory terminated; gold-plated connectors of high contact stability (spade or banana, depending on the version); bi-wire separation on the speaker side
Electrical parameters (indicative of high-end speaker cables; manufacturer does not release formal figures): capacitance approximately 50–200 pF/m, inductance ~0.5–1.0 μH/m, resistance <10 mΩ/m
Polarity and labeling: clearly marked channels and direction
Sound characteristics
Neutral tonal balance with very low levels of grain and noise, excellent instrument separation and accurate stereo staging. Solid, well-controlled bass; natural environment without thickening; clean, non-resonant treble. The dynamic transmission remains stable at higher volumes with preserved microdynamics.
Compatibility and application
Ideal for amplifiers and speakers with bi-wire connections (integrated, stereo and monoblock configurations; transistor or tube). The length of 1 m is particularly suitable when the amplifiers are close to the speakers (eg monoblocks). Recommended for medium and high sensitivity speakers and systems that strive for neutrality without tonal "tuning" with a cable.
Condition and maintenance
Condition: used, excellent. Contact surfaces clean and undamaged; insulation without folds and cracks. No need for service; it is recommended to periodically clean the connector with a suitable agent and avoid sharp bending.
