Impedence - multiple speakers in each channel

[Donivlapog]

If one chooses to have 14 speakers in a 7 channel receiver in series or in parallel, lets say a Denon 2700h paired with 14 Micca 0o0 mini bookshelves
Either...
1) In series (or)
2) In parallel

Would the stage blow up? Or the signal would share and the throw would be from different directions covering a larger room however with same volume levels and is indeed done by some seasoned campaigners.

Two gentlemen gave me two responses respectively (Former-as to blow up the amp and or speakers and latter - it would be a smart idea actually)

If you do use 14 speakers, connected to 7 channels of the AVR, you will need to connect 2 speaker in series for each of the 7 channels.

Connecting 2 speakers in parallel, on each of the 7 channels will almost certainly overload the AVR, with a high probability of failure of the AVR and / or the speakers.

The speakers are each specified (on the manufacturer's website) as "4 to 8 ohms" ... while the AVR is specified to feed 8 ohms.
The AVR driving speaker impedance of more than 8 ohms, is comfortable (ie 2 speakers in series will be 8 to 16 ohms)

However driving 2 speakers in parallel per channel implies a resultant impedance of 2 to 4 ohms.... almost certain to distort if not damage the AVR & / or speakers.

My post is purely from the point of view of electrical characteristics.... and not on sound quality or desirability of 14 rather than 7 speakers.

On a side note, careful reading of the AVR Specs indicates the Power Supply is capable of delivering upto 95x2= 190 Watts (RMS) total.

If this is shared between 7 channels, it implies less than 30 Watts per channel from the AVR with 7 channels driven.

+ the overall sound will decrease and worsen freq response curve, when connected in series, so bad idea
