ERR New Railsounds 5 Board

I face them down as a rule, though it really doesn't make much difference.  The biggest improvement in sound will come with a proper baffle on the speaker.  If the tender is sealed, it works pretty well as a baffle, but a proper baffle will be better.

If you have the room in the tender, spray can lids sealed around the speaker back really make a huge difference in the sound quality, and they'll increase the volume as well.  The baffle enhances the bass, which is pretty poor for most little speakers.

The kits came with the baby fat boy speaker (40mm) with plastic baffle. I will probably use this for the rest of my smaller Northern upgrades (Rock Island, Lackawanna and Northern Pacific).

I have a few of the regular size fat boy speakers (50mm) with baffles I bought from Lionel but will probably use them in my Reading and Chessie T1's when I do those upgrades.

I have a ton of the little speakers from ERR upgrades, so I'm set for life on those.

I know the feeling, I have extra a few of the baby fat speakers and a ton of the old speakers used in the first generation railsounds, and Sound of Steam.

Now I need to figure out what to do with my old RS4 power board and sound chips. I have a few extra sound chips laying around.

I occasionally use some of the RS4 stuff in seldom run engines, it's nice to have some sound as opposed to no sound.  I have lots of little steamer tender motherboards, so I can just use one of those and connected it to any standard TMCC package.
