Lionel sound units can sound like that... all it takes is a little willing to work.
Case in point:
Heres a basic TMCC Railsounds FT unit that I used as a test bed; since the Tang Band speakers are 4ohm, I needed to compensate. In this case, below, I used the Tang Band in series with a laptop speaker to get the required resistance and the sound was amazing.
Thanks,
Mario
great sound. Can you get it in there?

In my case, these speakers are the same length and thickness as the fuel tank. So I'm going to have the fuel tank machined so it's just a shell, and screw the speaker to the under side of the frame.
Eventually.
thanks!

wow, that sounds much better than the other speaker alone

I've tried several different setups, and the laptop speakers that you linked were from an old laptop; 2005-ish.
I've created a playlist which includes all the speakers tested, and the frequency analyzer results for each one.
Thanks!

Having a little fun switching on Austin Bill's great layout with a recent DCC sound installation in an Overland O scale ATSF SD75M using an ESU Loksound XL 4.0 with a Tang Band T1-1295S speaker and a Visaton SC 4.7ND speaker (with custom made plastic enclosure) each connected to a separate speaker channel. I was trying to work the throttle and video camera so forgive me if speeds weren't always prototypical looking. Also, I forgot to ring bell and blow the horn until about 3/4 the way through the video. Doh!
The Tang Band speaker really adds some nice bass to the normally high-pitched EMD prime mover (especially in model-sized sound). So if you like that modern EMD sound , then put on some headphones and crank it up!

VERY cool! Running and sounding!
riogrande491 posted:Even larger speakers than the one Mario referenced can be fitted in covered wagons such as single-tower drive P&D F3s. Here is a near-field recording I made of a Tang Band 1828SD speaker module. Its passive bass radiator extends useful bass down to about 75-100 Hz. It is being driven by a Loksound V4L decoder playing a 567 B/C 76311 sound file. Installation will require machining a large hole in the brass frame so that the passive radiator end can pass through and fire down towards the rails. When this recording was made, I held the speaker vertically, about 1/2" above the desk top, in the same position as it will be mounted. Sound from the active driver will escape through etched chicken wire dynamic brake grills on the side and top of the car body.
If you have external computer speakers, turn them up!

Bob, Sources for the TB 1828SD show different dimensions. One description shows 2 5/16" x 2 5/16" and another says 2". Is 2" the cone diameter and 2 5/16" the frame width? I have not found many applications where you can fit a speaker larger than 2" or 50mm diameter. I am surprised they will fit in an F3.
Also the link above shows a 4 ohm speaker. Does this come in an 8 ohm version you know of?
Pete
I can help!
the Tang Band website has all the dimensions for the speakers, surrounds and shells, if equipped.
The 1828SD is here: http://www.tb-speaker.com/products/t1-1828sd
For inches, just divide by 25.4.
Thanks!
Mario
Think of 2 inch as a "class" of speaker, not an exact dimension. The unit is not too wide for a P&D F3 body shell. The front porthole window glass inserts may need modification if the speaker is attached to the frame. Sound exits the car body through dynamic brake screens on the top and car body air intakes on the sides. Some P&D F-unit shells have molded filters on the sides, but those can be removed with a little care.
Unfortunately the speaker is definitely too tall, so a hole needs to be milled through the brass frame to accommodate the passive driver that extends bass response by about an octave.
Note that the HO decoder is just for acoustic testing. The 8414 Pittman motor has a stall current of about 10 Amps so a V4L will be used.
Some of the front motor mount and bits of the plastic I-beams under the frame must also be trimmed. The speaker will probably be glued to the frame with silicone caulk.
The cab insert shown does not come with the P&D kit. It is part of a very nice cab detail kit available separately. Here is one I built in 2004.
All the best.
As usual Bob,
Such a privilege to have your share your genius.

Geepers! I thought there were ALCos in the room and the FM is terrific! I would hope that ERR could do something similar.
Penn Division posted:Folks,
Yes, this is my work, here @ Forsyth Rail Services-Gibson Shops, and yes, the sounds are emanating from under the hood of the model.
The loco is a C&LS (Car and Locomotive Shops) PRR Train Master.
It sports dual Pittman motors, a ball-bearing drivetrain, and belongs to a Client from Florida. It was custom-fitted with a 6 amp QSI Titan Magnum decoder, running a modified Q3 Fairbanks-Morse 38D-12 sound file. Speaker is a TDS 1.22HB with a custom enclosure.
It also has individual, sound-synchronized, micro-motor driven cooling fans. Here's a video of them spinning up.

I was ready to reply and say "Ask Matt, he'll let you know."
That does sound great just like that 70 toner!

I know a lot of you guys don't seem to give a crap about things like this, but the locomotive under discussion here is a Fairbanks Morse "Train Master." It's two words and it's a proper trade name. Calling it a "trainmaster" is like calling a prized and classic Corvette a "chevy."
A "trainmaster" is a middle management company officer on a railroad.
