Sometimes it works,I think crossovers need to be designed with the extra wire inserted into the crossover in mind. Many speakers have split crossovers as an afterthought. I have always perceived more detail and more impressive imaging when bi wiring but also less coherence between the different drivers. I think a lot of the differce also comes from the extra conductor material. Do a true comparison:run double cable but listen with and without the terminal links. In the end I have always preferred single wiring, it is more euphonic and coherent with more beauty in the mids.
