Tsunami 2 speaker setup -series or parallel?????

[nebrzephyr]

OK...so I know the Tsunami is rated for 8 ohm load. I'm not great on the electronics but I believe two 8 Ohm speakers -

in series would be 4 ohm
in parallel would be 16 ohm

So which approach is best considering LOAD on the Tsunami?

Also, what affect is there on sound? In other words, if wired one way versus the other do you in affect negate enough of the sound of two speakers that it is no better that a single speaker?

Thanks. Bob

Just the opposite Bob - in series, you ADD them. in parallel you (simply put) divide the highest rated speaker by the number of speakers (8 divided by 2 = 4) There's more math to it than that, but you'll be correct if both your speakers are identical. The problems come in when you are using two dissimilar speakers.

Tsunami decoders should not be used with a load of less that 8 ohms (unlike Loksound), so you will need to run them in series. If you want the highest efficiency, use two 4 ohm speakers in series for an 8 ohm load.

To wire two speakers in series, one wire from the decoder goes to the + on the first speaker. The - from the first speaker goes to the + of the second speaker and the - from the second speaker goes back to the decoder. Doesn't matter which wires you use from the decoder, but the wires between the speakers must be correct.

Two speakers will give you more overall volume IF you have the room for them. We can't go bigger, so we go more !

Thanks Mark. I knew it was more involved than I knew. I'll see what I can do with 2 "sugar cubes".
