You can find 2" 16 ohm speakers in all sorts of places.  Look for one rated between 1W and 3W at 16 ohms, it'll work fine.  Are you sure it's the speaker?

One of the things I've been looking at is good quality H.O. speakers for DCC decoders. Most are 8-ohm/2 watt, but have enclosures and are small enough so you can put two of them in series to get your 16 ohms (or in parallel for 4 ohms). Depending on how things are arranged in the tender, you might be able to use this as an option.

No. But everything else works fine and its about 16 yrs old, so its probably time.

I've used this one with good results. Last summer I replaced every speaker in every engine. Much clearer sound in all of them.

One thing to check with a garbled speaker is to see if it picked up any stray metal pieces from running it.  A small screw, nail, or wire can make the speaker "rattle".  Eric from Eric's Trains has a video on Youtube if you need a how to guide.

I started looking online last night.  I saw this one but at less than a dollar I was a little worried about "getting what I paid for" type of quality.  Thanks for letting me know you have used it successfully already.

Started trading email with Midge. She asked for a picture and I am glad she did.

The installed speaker is not the same as what the BOM said it was. 

The best I can tell it is still a Star, but I can't tell if the first letter is a F or a P, but it looks like FR-050-A1421. What is clear is that a 16 ohm, 5 watt speaker, not 2 watt as called out.  

Also some of the coating around the diameter of the magnet has frayed. I don't know if this is cosmetic or related to the garbled sound.

By the way is there supposed to be a cover over this ?

GET RID OF THAT SPEAKER!

The flaking is a sure sign of a speaker going bad.

You can use almost any 16 ohm 2" speaker in the 2-5 watt range, I've used a host of different ones, depending on the situation.

Working on it GRJ!!  I  am glad I didn't order one yet, I would have gotten something underpowered. 

I have speakers if you needed.  Both the BF-0000033 shown, or your originally called for speaker.  E-mail in profile. G

Get a 16Ω fatboy from Lionel.  It will sound better and you will not have to deal the the speedy delivery of the locos OM

Dave,

Thanks for chiming in.  What is the difference between a "fatboy" and any other speaker?

Stronger magnet for one thing!

The Fatboy will typically have better bass, and usually renders more accurate sound.

Sent you an email.

Okay, so I ordered a replacement speaker.  

Now, since there is some room to mount the speaker a little higher, would there be any benefit to trying to make a cylinder of some kind to create a sound chamber? Admittedly I probably won't get more than 5/8", so I'm not sure it's worth the trouble.

You might get some benefit by making a tube as tall as possible and covering the top as well.  Airtight is best for a baffle, or as close as you can get.

Not being too adventurous, I ordered an in- kind speaker replacement from ggg.  I don't know if speaker magnets lose strength over time, but the new one definitely had a stronger magnet!  Here's a side by side with the new one installed.

And since we are dealing with a speaker replacement here's an obligatory how-does-it-sound? clip.

This was with the sound turned way down.

As long as the tender was open she got a replacement battery.  Next up is some lube for the gears, four new traction tires and she'll be good to go for another million miles��

(edit - in all honesty at first it was dead quite, and I thought I somehow fried the new speaker while soldering the leads.  That's when I remembered it was still unplugged inside the shell!)

The metal flaking is the issue, and internally it gets around the coil preventing proper operations.  I did find out that the manufacture is no longer making that speaker with reasonable minimum orders and MTH is looking for an alternative.  G

Given the performance of the speaker, that may be a blessing in disguise!

Not the same OEM as the original. So no blessing. G

I got a note from Deb at MTH and they no longer have the much needed BF-0000033 speakers anymore ( 5 watt, 16 ohm ) and do not plan to restock (like GGG posted). Any recommended replacements?

Lionel lists many 16 ohm speakers in stock including both versions of the Fatboys. Take your pick.

Pete

I saw those, but nothing close to a 5 watt rating.

You don't really need a 5W rated speaker for that task.

Jason, Said they were researching an alternative source. G

One source is Moyer Electronics in Pottsville PA. They have a website, if you want their phone number my email is in my profile.

I hope they keep the inventory more up to date than their free software page.  An example...

Windows 98?  The newest O/S on there is XP!

Xp being listed is probably the least thing wrong.  VCR's, turntables, and answering machines have all been outlived by toy trains!  In all seriousness I did notice when I initially started looking for parts that the mth and supporting documentation seemed to be seriously out of date.

Parts Express has something that fits those specs: https://www.parts-express.com/...31#lblProductDetails

That speaker will work fine for PS/1 locomotives.

Can a PS2 locomotive using these bad 16ohm 5W STAR speakers be replaced with 8ohm or 4ohm speakers... or does the PS2 audio amp really only support 16ohm speakers?

Thanks.

If it's a 5V board, use a 16 ohm speaker.  For 3V boards or PS/3, use a 4 ohm speaker.

Thanks John.  Bet I asked you that once before, but couldn't find the email, and couldn't find an answer here.  Have fun with that new train room.

Can I revive this topic? I have a chessie steamer ( round charging port ie: 5 V? )  with the same MTH star spkr shown above....same flaking spker,same crappy spkr. Ordered one from the bay" (a link that I got from GRJ awhile back..but things change with time)  a "PS2 MTH  steam replacement spkr" Got it in...nothing like the old one except it looks like it could fit,,,same diameter. New one is 8 ohm 2 w with REAL small magnet, old one is 16 ohm 5 watt and a huge magnet for a 2" spkr.  I will check a couple of links above...but, since this topic is from 2017 I wondered if anyone had a better source here, not what it is nearly 2024!! Thanks for any and all feed back. Gotta run and try to return a speaker that is not right to a seller that has a "no returns" policy!  See attached picts Greg

Replacing a 16  ohm with an 8 ohm is a bad idea.

Let's cut straight to the chase. It's this simple, you have a PS2 5V because of the round charging port and 9V style rechargeable battery, which takes a 16 Ohm speaker.

If you install an 8 Ohm speaker or 4 Ohm, this loads the amplifier which is already probably near it's thermal limits without heatshink.

This is not something to mess around with if you want to get maximum life out of that semi fragile PS2 5V board. In other words, cannot recommend installing that new 8 Ohm speaker.

Last- the seller sold you something with a specification and possibly pictures. They can have the no return policy all they want- if you have evidence (example the pictures and marked rating) of your received speaker doesn't match the auction details and description- then you have every right to dispute. This is a cautionary tale for those selling- your description better be perfect or else you open yourself to liability. It is a buyer centered platform and you can get caught out as a seller if there are any mistakes or errors in your listing.

Even worse, MTH parts and sales recently listed 16Ohm speakers for PS2 5V in the discount section of the site (last item on the page).

Yes, you need to have a 16 Ohm speaker load for the 5v PS2 boards. I test my speakers before installing them to ensure they have the correct resistance no matter what is printed on them. Many times I find a number 4 & 8 Ohm speakers are 3 and 7 Ohms respectively.

Vernon may disagree with me on this solution, in the past, I cheated on one of my 5V engines and used an 8 Ohm speaker but added an 8 Ohm resistor inline to dummy the load up to 16 Ohms. This will make the speaker quieter but not by much. I ran this on an old RK engine that didn't have much value so if I blew the board... not a big deal.  So far, 7 years and 225 hours of runtime later, it still runs & sounds like a champ.
