SPEAKER CROSSOVER NETWORKS ABSTRACT OF THE DISCLOSURE The invention comprises improved electroacoustic audio speaker cross- over networks. The improvements comprise both the addition of various passive elements and a novel inductively coupled circuit configuration. The improvements are applied to low pass and nigh pass networks and combinations thereof. In the preferred embodiments a separate electrical circuit is inductively coupled to the filter network. The physical configuration of the separate circuit can be easily adjusted to counter variations in individual speaker performance parameters. Thus, production variations in speakers from the same manufacturer or among the products of different manufacturers can be overcome and a better matching of speakers provided. In the simplest embodiment the separate inductively coupled circuit comprises a copper ring placed within an inductive coil of the filter. Adjust- ment is accomplished by adjusting the physical location within the coil or by small changes in the physical dimensions of the ring.
