In a typical speaker pair that is wired to the Amp, each speaker box contains two drive units as a minimum, that do bass, mid range and what a tweeter does.

So no, your post does not sound right.

You can connect four 8 ohm speakers to one Amp:

What type of speakers have different connections for bass, midrange, and tweeters?

In my audiophile days I had my Linn system bi-amped. Disconnect the crossover (the speakers were designed for this option) and use a pre-amp and dual power amps, one to drive the main speakers and one for the tweeters. Was the sound better: yes - to my ears way back then - though not necessarily enough to truly justify the cost! 
 

A lesser/cheaper way was bi wiring using two speaker cable runs from one amp to speakers with the necessary four terminals. Neither made a difference worth the effort. Active speakers like Sonos now use a dedicated amp for each drive unit inside the box with the crossover done upstream of the amps allowing for more control over the final outcome.

But I don’t think the OP is referring to any of this...
