In this day and age, 99% of the time a normal person does not need to worry about DCC decoder CVs. that is for fine tuning and customizations. I seldom access CVs. Following the directions on the controller and it will make the translation from what you want it to do into CVs automatically. In programming that loco address you changed CVs 39, 14, 15, and probably few others. It is unnecessary knowledge. Just like typing on the computer you don't need to know that the Intel processor had to load the storage address an set a base register in order to enable the screen memory buffer.found a Super Chief Xtra Duplex Radio Equipped starter set new and could not resist the 1/2 price offer. I just set it up and programed my first loco address...I know not a big step but one of many to come. Lots of reading to do. CV's are still a little bit of a mystery.
Speaker placement is more an art than a science. While there is tons of engineering techno babble that can be applied it usually boils down to your ears. Upward firing speakers will generally produce a louder sound that is more directional. That is your ears will be able to localize it better. Downward firing your ears don't hear the sound directly but bounced off the track. It is harder to tell the sound is coming from the tender rather than the loco. Generally one can fit a larger downward firing speaker into the same amount of space in a tender as long as it is not a Vandy. Vanderbilt tenders usually always have to be upward firing. I've had luck and failure with both types.pros and cons of which direction the speaker should face ???.
I guess I would say try not to burn any bridges while mounting the speaker. That is, if you make it downward firing don't cut a hole that is so huge and gaping that it can't be covered back over with a sheet of styrene. Nor would one want to make a hole in the coal that could not be easily recovered for an upward firing one.
