The Wire

BEL cables are intended for use in installations requiring a maximum transfer of information.  Systems often use the filtering effect of their cables to accomodate some particular distortions but the better systems will be able to use the superior performance of BEL wire.

In our cable measurements, other cables show aberrations starting in the low mid-range and increasing with frequency.  Such cables are linearized only with significant amounts of compensation.  Since BEL cable provides ten times the bandwidth capabilities of other cables, it needs no compensation and information is not lost in the process.

Magnetic Field Compensation is responsible for the unique performance characteristics of BEL cable.  The virtual elimination of series reactance creates a transparent coupling with a resistive impedance.   By eliminating a wire's non-linear component (series reactance), we have created a low impedance, broadband cable of unmatched linearity.

The low impedance created by this technique provides superior noise immunity and reduced sensitivity to placement.  It is also the reason that BEL speaker cable is the first to provide full control of the speaker over the entire audio band.  Cables place a damping factor in series with the amplifier.  A high impedance cable is the same as an amplifier  with poor damping and the result is the same - ringing.

With the elimination of series reactance leaving only a benign linear resistance to consider, cable thickness needs are dramatically reduced.  Cables need not be gargantuan rigid devices that are difficult to use.

Series reactance isolates an amplifier from its load, reducing the amplifier's control over it.  Magnetic field compensation increases capacitance while eliminating series reactance.  Capacitance is easily controlled by the amplifier and, without series reactance, control is achieved over the full length of the cable.

Cable capacitance is far less than that of some speakers; any drive difficulty suggests an inadequate amplifier design or a defective unit.
