It's an elegant improvement over DiAural in that it accomplishes this without a significant effect

Using speakers in series with one other, which usually happens both with inside-the-receiver speaker selectors

Speaker wire, especially in the case of long wire runs.

This has the practical effect of greatly reducing the main problems associated with:

a speaker's impedance for the purpose of reducing the adverse effects of series resistances.

HD-X3 technology has evolved naturally from its predecessor, DiAural. Like DiAural, it controls
