Speaker wiring??

Larry Behm · Post by **Larry Behm** » 11 Oct 2004 3:58 am

Two 4 ohm speakers wired in series is a total of _______ohms? Two 4 ohm speakers wired in parrallel is a total of ______ohms?

Will a Nashville 400 run best with either one of the above? What about out of phase speaker operation and speaker placement?

Two 4 ohm speakers wired in series= 8 ohms.
Two 4 ohm speakers wired in parallel= 2 ohms.

The Nashville 400 produces full output power into a 4 ohm speaker load. Any load other than 4 ohms, will produce less power.

The phase of speaker operation has to due with both cones moving in the same direction at the same time for the same signal polarity. That's why you connect all the red stuff together and then all the black stuff together and never the twain shall meet less you let the smoke out...

Just connect the stuff up symmetrically and you should achieve correct phasing.

Larry, what Mike is telling you is: DO NOT CONNECT TWO 4 OHM SPEAKERS TO YOUR AMP. If you want to use two speakers, you should connect two 8 ohm speakers in parallel. If you could find a 16 ohm speaker, you could connect it in parallel with your 4 ohm speaker for a total impedance of 3.2 ohms. (4x16)divided by (4+16)= 3.2 .........JD

So, I could have a 1501-4 on one side of my stereo amp and have two 12 inch 8 ohm speakers, wired parallel to one my other channel to balance the load. Correct ?

Yes Gary, you could do that with a stereo amp that was designed for a 4 ohm load. You will have a lot of equipment to move. I like to keep my equipment weight to a minimum. When I built a rack mount power amp system, I ran the amp in bridged mode and used one speaker. Larry is using a NV400 (not stereo).
