Title: Digitrax sound decoder SDH164D and speakers
Post by: New ChooChoo on May 23, 2011, 08:46:55 AM
   I bought this sound decoder just to get my feet wet so to speak and see if I like the way it works while not breaking the bank money wise. Its OK for me but it came with a 1" diameter speaker and I think it would sound a whole lot better with a larger oval speaker. Question is where do I get a 32 ohm speaker for this Digitrax decoder? I see alot of 4 ohm and 8 ohm speakers out there. Will they work? Don't want to destroy the decoder. Any ideas? Thanks guys!

Look at the below link. Do you have a baffle for the speaker? I use the 28mm speakers which are slightly over one inch diameter with baffles and they are quite nice. More info on you loco of choice would be a great help for advice.
I have never een any for 32 ohm.

   I have a Bachmann 4-8-8-4 and it came DCC ready so this was easy to install along with a small harness with the 8 pin plug. I know the decoder has a generic set of sounds but I wanted to get something low cost first to see how it performed. I was/am concerned about using an 8 ohm speaker as I dont know too much about the differences between the 8 and 32 ohm speakers. If an 8 ohm speaker will work then I will try it. Just dont want to damage the decoder right off the bat.
Thanks!

You also do not know the difference between a 4-8-4 and a 4-8-8-4, Bachmann only makes the 4-8-4, the 4-8-8-4 has an extra set of 8 drive wheels.
