Alright here's the quick and dirty. I've been living with a group of animals (goats, sheep, yaks, and camels) for a number of years now, doing long multi month trips on the trail with them. Starting to get spoiled and wanted to have a throw back to the days where I could listen to music on something other than a cell phone. I need a speaker that is light, size is less of an issue with packing on a camel, and I can always use it as a stool or even have a removable side to use it for storage on the move. But still not much bigger than 20x15x15. I am thinking a mono setup, paired with a high efficiency amplifier that I can power off the 12v battery/100w solar setup I have with me. It will be used outside or in a tent, and will be protected from the weather when necessary.
Pitch me some ideas if you got anything good (or a used amp or driver that you want to sell : ), and I promise to post some pics as this develops. Right now I'm leaning towards some type of class D amp with a .53 Karlsonator, although I'm trying to find a speaker with a neo magnet that could work in this design. Thanks in advance for all the feedback, good to see the forum again!

Here's one, but busts the budget
This one needs a super tweeter
At a glance, looks like 'slim pickins' for wide range

Musician thing for awhile was.
1/2 inch plywood with lightest you could find.
then bracing. keep weight down
I would do a stereo pair, and then mono single light neo 12"
for bass. all mounted in same unit.
Visaton BG17 simple, decent sensitivity
pair with tweet to clean up top end.
plenty battery powered boards with mono sub
and 150 Hz crossover. just make passive network for
tweet
Quick , quick temporary "build" for something better
than cell phone speakers is JBL Flip.
Also audiophiles like to make ear buds sound like
the end of the world. Which i agreed too.
Then someone gave me bluetooth pair for gift.
And bass is good, and very clear.
I go into another world at work now.
Amazing stereo " image" or whatever they
call it. for no charging fuss I have corded
headphones as backup

PM220 is interesting, that in a K12 has me intrigued. Should be efficient and less than5lb for the driver.
The Flip is just too plastic for me, and headphones are out as I definitely want a speaker. A dual BG17 with a 12" sub also seems like it would have to be larger than I would like, my goals size wise are around 20"x15"x15" or less.
But my desires are in the realm of musician, I am interested in light, efficient speakers and care less about a flat frequency response. Thanks for the thoughts, I'm still crawling through the forum and staring at this camel saddle trying to make a plan...
I'm currently listening to a pair of BG 17 drivers (Holst the planets) augmented in the bass by two QTX 902.536 61/2 inch PA drivers, the QTX drivers are in 10x7x5 inch (internal) boxes, so you could have a box double the volume with opposed drivers in, and the BG 17 drivers in aperiodic vented smaller enclosure built on top, although using the QTX drivers with tweeters would save weight and volume. I've been making some boxes from 6mm mdf with ribs and bracing, and I think 3.6mm ply with internal ribs would work. I'm currently using a tda 2822 amp (3 watt per channel) to power them and the QTX subs, I guess using 4 channels would be lighter than chokes for the subs. I wonder if a bandpass sub with a "hump" at 90 hz would work. Will there be lots of sand? If so a passive radiator might be better than a port.
A Dayton PA130 XKi is too little to use for a stool -but sounds very good with a Kinter 3118 ~$20 12 volt amplifier. which has switchable tone controls.
9mm Baltic birch plywood is great - 1/2" cheaper would do as I have one X
Ki with a 12" which does ok (can feel some flex)
I'll have to find that nice plan and edit
20"x15"x15" could be a 10 inch driver XKi
I have an 8 inch XKi made of 3/4" plywood which measures 11.5" wide by 10.25" deep by 15.5" high. Its tuned to ~60Hz with Beta 8cx
