8ohm or 4ohm ?

[jeffrice6]

stupid question here, for an external cb speaker do I want 8 or 4 ohm ? thanks

Almost positive on 8 ohm or two 4 ohm speakers in series to make 8 Good luck!!

2 four ohm speakers drops to 2 ohms

2 four ohm speakers drops to 2 ohms

pssst...2x4ohms in series=8
2x4ohms in parallel=2
hehe

I thought I was right. hehe

Any combination of one or more speakers which has a total impedence of between 8 and 16 ohms is fine.

hehe

or you could use (2) 4 0hms series/parallel and end up with 4 ohms again
hahahahaha

the answer to the original question rests mostly on the audio device in use. for example, the TA7222AP will deliver 5.8W of output into a 4 ohm load @ 13.2 VDC with less than 10% THD with a figure of .2% being typical........it will also deliver 9.3W of output into a 2 ohm load at the same specs while listing no typical THD figure except to say that is still <10%. a total load impedance of 2 - 4 ohms produces the best results. i use a pair of 3.2 ohm, 10.5 oz. mylar cone elements in parallel and output is above average and more than adequate.

generally speaking, the majority of these devices will deliver more power in almost direct proportion to the reduction of the load impedance.
