I-phone speakers update

[george stein]

Writing from the USA.  Several years ago there was a fair bit of discussion on using I-phone speakers, especially from I-phones # 4 and 5, as DCC sound speakers.  So, in November 2021, we're up to I-phone #13.   To those forum members who research such things: have any of the speakers since # 4 & 5 demonstrated improvement, equivalence, size advantage, etc.  The older 4 & 5 are getting both more expensive and hard to find.

I use iPhone 6. Not the S version.

This is a UK site.  Cut off the side extension and plug the small hole.

The important bit is the speaker’s impedance, which must match the sound decoder spec it is paired with.

iPhone 6 speakers seem to be 4ohms so run two in parallel for ESU.

They’re 8 ohms, so 2 in paralell is 4 ohms. It’s safe to use one on its own with esu too, it’s just quieter

 

Yes, sorry, a senior moment.

 

Used them myself so I should know.

Thanks for helpful comments.  Another question: would not two 8 ohm speakers wired in  SERIES be better for producing more sound with less demand on the speakers? 

 

Never quite understood the series vs parallel dual speaker wiring issue. ??

Yes thats the ideal set up, but beware of doing that on Zimo Micro decoders.

 

There are lots of brilliant speakers now available in both 4, 6 & 8Ohms for model trains.
