Looking for MTH part #

Anyone ?

This may be what you are looking for.  I use these in Williams NW-2 DCS conversions.  They are a direct fit for the williams unit in the tank.  If this is not your guy, let me know as I am sitting on many small speakers.  Rating 4 ohm 3 W.

Much appreciated Marty...............that is the one.

The writing is not present on the one I have.

Will email you off line.

Thanks

Dave

I have confirmed with MTH this part is not currently in stock.  Hopefully some forum member may be able to help you.

Thanks Marty

One of my favourite engines ...this little S2

Might someone have this speaker.......    BF0000050   4 ohm 3 watt.

I'm prepared to order several other parts as well if a responder might have them.

Or just the speaker would be great !

Thanks

Dave

I am always cruising looking on the net for speakers.   I saw this about a year ago and forget where.  I may have saved it. Hit my email Monday and I will ask contacts at MTH who made these.  

I have one in stock, e-mail me  G

Thanks Marty.  If you do have that information available on Monday, other forum members may benefit.

George ...GGG....stepped in to help me out with one speaker that he had available.

Thanks George

Dave

I have been going crazy looking for the info you need.  MTH will have them shortly.

Thanks Marty..........New developments........Here is where I am at.

I received and installed from George  -  MTH BF0000050 speaker into MTH S2 switcher 20-2500-1.

It is a 4 Ohm 3 Watt speaker.  Engine running and sounds very nice.

About the same time I received an order from MTH with speaker BF0000040.  This speaker is 8 Ohm 2 Watt.  MTH claims this speaker is correct.  When pressed they indicated either would work.

Both speakers are the same size physically.

I'm not sure what to think...............opinions?

Thanks

Dave

Dave,

FWIW, the 4 ohm speaker will be louder and handle more power with less distortion than the 8 ohm speaker.

Thanks Barry.

I'll just keep the 8 Ohm for a future job.

When you move up in ohm rating for a speaker you move in the safe direction but lose volume as the speaker higher impedance limits current flow through the speaker hence (Power/Watts).  So lower sounds.

Going to low is in the unsafe direction and can damage the audio amp.

16 ohms was PS-2 5V

8 ohms was PS-1 and Loco Sounds and some accessories with sounds

4 ohms is PS-2 3V and now PS-3. 

For some of these specialty speakers in smaller PS-2 3V engine I have seen 8 ohm versus 4 ohm speakers.  I imagine it was supply issues. G

Thanks George

MTH did mention exactly that......probably supply issue at the time of production.

So they say 8 ohm 2 watt is the correct one but the 4 ohm 3 watt works very well and I would not want any less sound.  Clarity is also excellent.

MTH also advises that the 4 ohm 3 watt is "currently unavailable".

You can get these PUI 4ohm 3W 28x40mm speakers from mouser electronics:

I was not aware of this option.
