Is it possible to make relatively small lets say under 50 cm side boombox based on Danley Synergy?
Using 3 or 4 inch drivers... or the size is matter?
If it is possible how to calculate it?

I've thought about this in the past, too. I quickly came to the conclusion that while it may indeed be entirely possible to build a very small portable system based on Synergy principles, I didn't think the complication involved and time required would be worth it. Mainly, the horns wouldn't be large enough to obtain much advantage over an ordinary horn for a treble driver. If you're planning to use the system outdoors or in large spaces, I think you'd be better off using a simpler approach, such as a typical vented 2-way with large surface area (Sd). A pair of pro coaxial drivers in a large portable boom box would be cool to see. However, I'm still interested in what others may have to say. Hopefully someone else more knowledgeable about Synergy design will chime in.
Synergy horns are all about pattern control and not so much about horn loading. Pattern control is beneficial in pro sound and also indoors for Hifi. There's little to be gained by doing a Synergy boom box.
For a boombox a wide or even an omnidirectional pattern is preferrable, which does not work that well with most horns.
As far as I understand Danley sell their Sinergy mainly for outdoors or big spaces. So if do not need to cover football feild small version could be Ok.
My idea to put in one box small amp and "old" smartphone to make LITTLEbig smart speaker with good sound.
I have made two speakers with 4 drivers line array but they are too directional. There is a tiny sweetspot with good sound still bit too high))
Now I'd like to make one (or two) bigger for fast and deeper sound less sensitive to location. I do need it to be small enough to transport by car not occupying the whole trunk.

Yes: 0
No: 3
.........maybe if its 30" wide x 18" high x 20" deep. Thats smaller than a trunk.

I have built a 3-way synergy boombox 6 years ago.
In this dutch thread you can find some information: http://http://zelfbouwaudio.nl/forum/viewtopic.php?f=3&t=18202&sid=b3b363c06db96d85bb00ce8274151ae1
I have used some old Philips components:
2x AD0160/t4
2x AD5060/sq4
2x AD8066/w4
Now I am looking for an upgrade with a real compression driver, I have bought me a BMS 4549-8 to build a SH95 style 2-way synergy. The bass/midrange drivers should be the AD8066/w4 drivers again.
An externally hosted image should be here but it was not working when we last tested it.

The AD8066/w4 woofers are not really suited for horn loading with their weak motors: BL = 5 TM.
I doubt if building a unity horn offers an advantage in a boombox, as the small size means that the woofers will be limiting the SPL to hi-fi levels. Then there is no need for a horn and a single full range driver can cover the mid to high frequency range. You get the same point source behaviour.
