8 Ohm Speakers in a series?

Question

I have a nice Karaoke system (GIG STAR), I would like to hook 6 speakers (3 off of the left & 3 off the right). All the speakers are 8 Ohm 90w to 120w.

The machine instruction book says to only hook up 1 speaker on each side, 8 ohm each.... well ok but I want to spread the sound around a room more (not louder, just different angles).

If I hook up the speakers in a series the Impedance (ohm's I guess) are higher, therefore safer for the machine? Right??

Thanks for any help and Ideas!! :-)

Answer 1

connect all the speakar  spekars paralel.from point one to next

so that the cable length will be less as well as the load will distrubute.

no harm to the system also

Tr=1/r+1/r2= paralel

tr= r1+r2 =  serious increse in total resistene  

Answer 2

Yes, connecting three 8 ohm 'speakers in series gives a total impedance of 24 ohms and is, as you say, safer.

However, by doing that, the total power developed in the 24 ohm load will be one third of the power in a single load of 8 ohms.  So, each of the three series connected 'speakers will develop one ninth of the power it had before, and sound about half as loud as it did before.  

An example:

If your amplifier develops 100W in 8 ohms, it will develop only 33.33W in 24 ohms, i.e. 11.11W in each of the three series connected 8 ohm 'speakers.  

Connecting three 'speakers in parallel gives an impedance of 2.66 ohms, which is far too low for safety.  

The series option is to be preferred and I am sure you will find it satisfactory.
