I think this is a great idea, particularly the subs. Relatively light weight is an excellent idea and like many of you I don't want to or even should carry heavy objects any more.
I also think that whatever sub is chosen it should be a relatively well known inexpensive design so that most of the DIY community could build it as well. The two designs I would be interested in are the following tapped horn and the bucket sub.

Not sure about the bucket sub. It's still a standard plastic five gallon drum from a home improvement store. I remember watching a YouTube video where some fly by night car audio shop jerry-rigged a truck install which included subs in buckets in a repurposed speaker box.
The small driver/transmission line works, but it isn't a complete substitute for a real sub. Along the same lines, what about a single driver full-range speaker in a transmission line?
What about the open baffle type like HAL has?
