In Reply to: Technical question about internal biwire cables posted by Matthew G. on July 24, 2015 at 18:43:56:
Whether or not it's an internal or external bi-wire cable, a bi-wire cable allows each crossover section to be separately connected directly to the amplifier outputs rather than one section (high-pass or low-pass) being bridged/jumped to the other at the loudspeaker end. The purpose of a bi-wire connection is to avoid the EMF backwave of the woofer from affecting the performance of the tweeter. A bi-wire cable simply keeps the crossover sections apart from each other, all the way from the amplifier outputs to each crossover section.
An internal bi-wire cable typically divides the amount of conductors in half (or thereabouts) for a bi-wire application, which decreases the aggregate/effective gauge in a manner that essentially makes the conductivity of the cable much less efficient. As a result, the cable may present "a cleaner but thinner sound" as you say, with a leaner tonal characteristic. When the same cable is connected to the loudspeaker via the use of bi-wire jumpers, the total cross section of the cable is connected to both crossover sections, so a fuller-bodied tonal characteristic may be a result, however at the expense of no longer providing the sonic benefits of a bi-wire connection.
This aspect is another important reason why an external bi-wire cable configuration is preferred vs. an internal bi-wire configuration, since the entire cross section (all of the conductors) of each of the two cables can be used for each crossover section, as well as the ability to keep the two cables apart from each other in order to help mitigate interactions between each cables electromagnetic fields.
