I have tried to explain this a few ways,but I'll try one more time.
3 Types of Amplification!
Horizontal Amping--Does not require Monoblocks
Vertical Amping--Need Monoblocks
Bi-Amping
Horizontal means you can use 1 amp to drive the woofers in both channels and another amp to drive the Tweeters in both channles and another amp to drive the Mid Drivers in both channels.So you have 3 amps driving particular drivers in both channels.
Most speakers that allow to use seperate amps that are 3-way speakers only have a 2 sets of binding post which means they combine driving the Mids\Tweeters as one.Which in turn means you would have :
One amp for the L\R Channel Mid\Tweeters
One amp for the L\R Channel Woofers
That is Horizontal Amping because you are using the amps to drive the same drivers in L\R Cahnnels and even if you are able to use another amp to drive that set of Tweeters in both channels by adding another amp you are still Horizontally driving the speakers
Then you can get a 3-way Outboard crossover unit which allows for using a seperate amp to drive each driver.This is Vertical amping.
So lets start with the Left Channel in a 3-way speaker using Monoblocks:You would need 3 sets of Monoblocks
1 amp for the left channel Tweeter
1 amp for the left channel Mid Driver
1 amp for the Left Channel Woofer Driver
For the Right Channel
1 amp for the right channel Tweeter
1 amp for the right channel Mid Driver
1 amp for the right Channel Woofer Driver
Bi-amping is just adding power and nothing more.It is not really advantageous from any other point of veiw.Horizontal and Vertical amping helps with efficientcy .Verical being the most advantageous because it is using a Dedicated amp for each driver.It also allows for less crosstalk and less distortion from occuring.
