School bus / Tiny Home Speaker Recommendation?

REL T Zero. 

I’ve really got no recommendations, but just want to say how cool that is. I’d like to see some pics if you are so inclined.

I've done a few office and small room systems with these and it works really well

I've been considering building a tinny home and this exact issue has been on my thoughts, as most tinny homes are no wider then 8" its hard to plan out a listening space. my conclusions are if you want the proper spatial q's, sound stage, etc. you need to go near field or have the room optimized acoustically. just about any smaller stand mounts should work fine. adding a sub for bass if you need it, note you may also use a sub to help with room nodes. 

the biggest thing to consider is room acoustic treatment to optimize room interaction. with that you can get a surprisingly large speaker in that space. bass is a concern too much will be noticeable. one other thing to consider is many tinny homes are all open so its actually a larger space to fill then you may at first consider.  its the width that is the limiting factor for most tinny homes. 

Personally I've decided to go wider with my build probably 10-12" so i wont be able to tow it as easily but I'll gain in listening space size. 

I'd recommend you use one of the room acoustic companies room size calculators ( GIK has one i believe)  and see what can fit in your space and where you may need room treatment. most of these are free to use.
