Serial, Paralel (and connect different Ohms speakers)

[Guest georgeDV]

hello you all. thank you again. !
I post there as a general question, maybe a basic question. 
I imagine the example "deflect" is not a good way to use and connect speakers.
and I suppose the traditional Serial connection is better. 
if I'm wrong, if there is something bad about
please, let me know.

Parallel and Series connections.

 

This calculator will tell you the impedance the amplifier will see with given speakers of different impedance ratings in each type of connection.

Amplifiers have trouble with lower impedance loads unless the amplifier produces lots of current and most don't produce lots of current, a 6ohm speaker and a 4ohm speaker in parallel will produce a load of 2.40 Ω which is a difficult load for most amplifiers.

Also the rating on the back of those speakers is a nominal one and at certain frequencies they could drop even lower.

 

Edit: in your example on the right you have a connecting plan that would rarely be done, having one pair on one channel and the other pair on the other. So I don't know what this deflect system is and have never seen it done.

I don't quite understand the ways you are connecting the speakers from those diagrams. I thought the connections would be in one of the forms shown in that link.

yes, ! thank you , useful information, as seen in forums and videos so I'm sure that's the way to connect speakers if it was needed.
I really doubt the examples marked as independent can be useful or better, I've never seen that even in audio car or live shows or a party dance. with just a visual review we know.
