Make speaker louder?

Sound volume maximums are all over the place I find. Some really put out like the K-Line TMCC engines. Others you can hardly hear and there is everything in between. 

I don't think it is the speaker in your case rather the sound board driving it.

I wonder if anyone sells something that would increase output wattage. 

Due to government regulations on toy trains starter set locos have a limit to the number of decibels tey can put out.  There was an earlier thread about this that included a fix from Lionel.  I don't know if that correction would pertain to your ERR Sound Commander or not.

I believe that fix was only for weak air whistles.

It would not be the same as any fix for speaker volume.

When you say "enclosure", is it a sealed enclosure on the back of the speaker?  You'll improve the volume and bass response of a speaker considerably with a sealed baffle on the rear.

The discontinued Sound Commander only had 1 watt power rating along with fairly cheap speaker. ERR's newer Railsounds Commander I think is rated for 5 watts (like RS4 and up) plus a mini Fatboy speaker. You would have to install a audio power amplifier to increase the volume. There are some kits out there on the web that might work.

Where are you coming up with 5 watts for RS4?  The output amplifier that drives the speaker is an LM4861M, rated at a maximum of 1.5W with 10% THD, in other words it's working it's butt off! 

I wonder if there is enough room in the Legacy K4 tender for this amp. I know it won't fit in my U-boat even if I could get the top off.

I don't think the amp is the answer.  In any case, I'm sure there are far smaller amplifiers to be had if you really wanted to go this way.

Here's one: http://www.ebay.com/itm/High-P...;hash=item43ba79646c

Check jumper on board.  You may have unit in low sound level.  In cmd you set jumper to high and use command control to adjust.

Here is a picture of the speaker. So to answer your question, Yes.

  Hello Tomix,

  I would strongly recommend taking the the speaker baffle off and filling/sealing it in with silicone sealant. I've had great success using this method. Be sure to put tape over the holes around the back of the speaker so as not to impede the cone.  

 You should have a significant volume increase, and have to lower it a bit giving you less static as a side bonus.

I agree with BigE, sealed is the operative word here.

Thanks for the help everyone. I will work on that and post my results when I am finished.
