I’ve been through the same thing putting together a mobile rig so I can record whilst travelling.
I started with some small Yamaha computer speakers which sounded awful but if the mix was good on them it seemed to travel well.
I then moved on to the JBL Control 2P which are self powered version of the Control 1. I found these a bit too coloured and quite heavy when travelling.
I’ve finally settled on the Genelec 8010 speakers which are incredible for their size. They lack the very bottom octave but you can check that on a good set of headphones. The midrange and sheer scale of the sound field you get from these are incredible, and I sometimes forget I am listening to the little Genelecs rather than my main Dynaudio monitors.
Plus they are only 1.5kg each and made of string aluminium so great for travelling.
