Speaker recommendation for Walthers Mainline SD70Ace?
hotrodf1:
Hey all,
I finally have my first loco converted and running good, but the speaker that I got with my used LM3s is much too big to fit (and also lacking a baffle). Looking for a recommendation for speaker to fit in the stock location - unless for some reason that's a bad idea? It would be pointing down at the rails, and be passing through several 1/8" or so holes that are in the chassis.
One easy option would be the stock Walther speaker and enclosure (assuming I can call them and still get one).
This Streamlined backshop place has a ton of speakers too. Are these cube speakers any good? https://store.sbs4dcc.com/sugarcubespeakers.aspx
Or more of a normal speaker like this ESU 16 x 25? https://store.sbs4dcc.com/ESU50330Speaker16x25mm4ohm1wattw/SoundChamber.aspx
Looking for "bass" response although I know in such a small place it will be limited. Anyone have a favorite that's just really stellar?

Well, I've never used them (read too expensive after shipping and exchange rate) but Scale Sound Systems get a good rap and they even have a configuration for the Walthers Mainline SD70Ace: https://www.scalesoundsystems.com/product-page/walthers-mainline-sd70.
I know a member or two here have used SSS with good results. If you want real bass, then your pretty much on your own to hack away to fit the largest properly made speaker and baffle as possible. Some looking around on this forum will give you a few of KPacks installs that shows how he hit fit a large but really good bass driver into some models. It might give you some ideas, or a heart attack ;).
There is also some discussion here on making your own baffles with sugar cube speakers (again, some good info from KPack).

I'm one of the users who uses Scale Sound Systems speakers exclusively. They make that much difference.
If J.T. has one already to go for the Walthers SD70Ace, then you are "In like Flynn". Even if his designed speaker won't fit with your install of RailPro (i.e. Bowser SD40-2 - the LM-3S goes where the speaker should), he can help with his UFIT line.
Also, if he has an option for two speakers (and you can make it work), I heartily recommend doing the dual speakers!

Jeremy - when it comes to speakers you really have two options: 1.) fit in the stock space, or 2.) modify the model to fit it somewhere else.
I've messed around with speakers quite a bit. I used to make my own enclosures for sugar cubes, and would install 2 or 4 depending on space. At first I thought that they sounded spectacular. Then I experimented with Scale Sound Systems speakers. I quickly learned that my homemade speakers were vastly inferior to the SSS speakers. For ease of use and installation, the SSS speakers can't be beat. However, I liked their older speakers much more than their new ones. The old speakers could be ordered with two speakers installed in one enclosure, providing more and richer sound. The new ones are a single speaker and they just aren't as good as the old. Much better than most everything else, but I miss the old ones.
If you want bass, then really the only option is a speaker module from TB speakers. They come as a module with a decent sized driver and a passive radiator. These two combined produce low notes very well. They don't get nearly as loud as other speakers, but they also don't sound like nails on a chalkboard. Listening to most model railroad speakers is a form voluntary torture. The TB speakers are the only ones that can actually reproduce low notes....and paired with Railpro's newer sounds they are quite excellent.
The downside is the size. The only way to fit them is with some serious surgery to the locomotive. Large amount of the weight needs to be removed, and you need to be comfortable with soldering and running wires. Is it worth it? Yes. I have a few models with the TB speakers and they hand's down the best sounding models that I have. Not annoying to listen to. They sound about as good as you can get in HO scale. This video shows the installation in one of my models:

Thanks everyone for your ideas and thoughts. Much appreciated! I think I'll give the SSS stuff a shot to start with. He had a video there that did a comparison between the stock Walthers speaker and the Rectify series that he has, and it sure sounded a lot better than the stocker (no surprise I suppose).
Kevin, your videos have been so helpful. I know they take a ton of time. Thanks for sharing your love of the hobby (and your skills!).
I have dabbled in building hifi speakers also, and I have a 15" sub with a horn loaded enclosure that is crazy good. But that concept wouldn't work here as it would be too much space and not sure what would happen to the high freq sounds either. Maybe a sort of transmission line unit would work. Passive radiator also seems like a good concept too, as you said with the TB speakers. Seems like there's opportunity here, but with the space that's there maybe it's just not feasible.
Could perhaps have some fun with a 3D printer.
