Model Railroading > Who has best sound unit for a SD-7?Date: 01/24/20 11:46 Who has best sound unit for a SD-7? Author: tomstp Just bought a proto SD-7 Rio Grande engine. I already have a Broadway Ltd SD-9 with a very good and loud sound system in it. To up grade the Proto SD-7 what would be the best sound and Dcc system and speaker to put in it? I would want one with fair loud volume.

Personally, I would use a Nix board with an ESU 21 pin V5 decoder and an iPhone 4 speaker. Posted from Android Edited 1 time(s). Last edit at 01/24/20 15:54 by sixaxlecentury.

Or maybe the more important question: is the iPhone speaker 8 ohms? Date: 01/24/20 19:30 Re: Who has best sound unit for a SD-7? Author: sixaxlecentury I have done a few dual installs but don't feel its necessary. One is plenty.
