This implies a basic misunderstanding of what goes on when you wire two or more components with identical impedance characteristics in series.

"Dolby Surround" has nothing to do with what's going on here. "Dolby Surround" reproduction involves a decoding process that produces more than two channels of sound from an encoded source.

Please demonstrate how 4 midrange drivers of 4 ohms each can be wired to produce a total impedance of two ohms.

If an amplifier is rated to be able to drive a load of 4 ohms when bridged, it is usually safe to assume that it can also drive a load of 2 ohms on either channel instead.
