What's better for DSD LC and DSX ...2 spkr @ 16 ohms or 2 @ 4 ohms?

(I have this question in to Sountraxx forum and Sountraxx Support, but no response in two days...and I wanna build it today) 

I like to experiment with larger sound for narrow body locos by having
it follow in a "soundcar" piece of rolling stock. I have built
one...with four large oval speakers in 8 ohm config as shown in the
manuals...and external mini plug leads......

but I think it sounded no better than TWO large oval speakers.....but these 2 can't be wired to match 8 ohms....

I'm thinking it is better for the decoder to be running 2 @ 16 ohms and
turn the volume down, than 2 @ 4 ohms ever ever.

Ohms is a measurement of resistance the lower the ohmage the closer to a dead short so the higher the ohmage the better for the amplifier.

Two 16 Ohm speakers wired in parallel would be equivalent to 8 Ohms; in series would be 32 Ohms.  So two 4 Ohm speakers in series would be 8 Ohms, and in parallel would be only 2 Ohms.  SoundTraxx recommends 8 Ohm speakers.

Yes, thank you fellows.  That's what I thought. 

Yes, I forgot I could make 2 speakers come out a 8ohms using 16 ohm speakers....but I have a big box of the 8s I want to use up.

BTW..slightly different product, Digitrax now recommends using the 8 ohm speaker in place of the 32 ohm speaker already attached to the Soundbug.  The new models have had the 32 already swapped for an 8 ohm....and their support said just go ahead and attach an 8ohm to the old ones for a better sound....so the rest of that little sound decoder has not changed.
