Understanding BiWiring

Many of today’s speakers can be “BiWired”, meaning the speaker has separate inputs for the woofer and separate inputs for the higher frequencies. Should you BiWire? If so, should you BiWire with a single cable (Single BiWire/SBW) or with two separate cables (Double BiWire/DBW)?

Is BiWiring so important that you should spend twice as much on speaker cable? BiWiring is actually a way to get higher performance for the same expenditure. The BiWiring question is not about how much money to spend, but how to maximize performance and value.
