Single-wire spades from amp to biwire spkr posts?

There are multiple factors, such as how the crossover boards are implemented within the speaker, how the bi-wire cables are set up, and others. Some internally bi-wired cables simply split the number of wires between LF and MF/HF, while others double the wires inside of their bi-wired cables, like with my Purist Venustas. Other manufacturers offer double bi-wire cables that have two separate runs terminated together at the amp end, and some do that while using different gauge wires for LF than for MF/HF.

OK, thanks for that again.

This is what Im talking about, its still a giant loop, right? They are still all connected after the amp.I may be wrong but thats what it appears as.
