<{POST_SNAPBACK}>"It's sound, Jim, but not as we know it"
I had the opportunity to compare, side by side, an N gauge MRC sound fitted loco with a HO QSI fitted one. There's no contest and IMHO sound in N will never give anything like the same experience. As has already been said, you simply cannot fit a large enough speaker and the sound was horribly tinny.

***MRC sound is pretty bad to start with mind you - and QSI is about 10% distortion and way too loud most of the time. For micro work, only the Tsunami Micro (too big for UK N) and Loksound Micro (fits many UK N) are worth using
I've done a couple of dozen UK prototype loco's in N with sound. I've been asked to do many more but frequently say no as its not really practical in many UK loco's.
The space exists on many but it can be a real challenge even then... think milling machine and accuracy of work... milling things to be "a few thou of plastic or metal and a layer of paint" thick!!!
After advising the options and the likely result yet again, yet again it was still requested so currently I'm doing a Minitrix A4 for a client, and can get a reasonable result if I fit a 13x24 oval in the tender with a loksound Micro.
The trick will be to seal the enclosure for the speaker properly as this is critical in ANY install, despite what the punters who just "stick em in" say... and then I'll have to tweak the equalisation of the sound files to try to compensate for the speaker size...
a real pain in the B - and several hours of work.
Bass of any kind - or anything much above 300Hz is lost with all but the best speakers and the small size of N really doen't help this much.
So... personally - if you have a US articulated or a big US diesel, then it can be made to sound really nice - but all but the largest UK steam loco's are always a bit of a compromise. UK diesels are not big on space, and metal needs removing to fit sound decoders and speakers.
The BIG downside of this is removal of weight - already N has insufficient mass for good pickup - taking out more is risking good running on all but perfectly clean track...
My recommendation - either change up in scale or forget sound in UK N loc'os. Get a computer speaker system and mount it in & under the layout, play a diesel soundtrack.... quarter the cost, ten times the fidelity....
