I thought the whole idea of this system was portability. The specs say: "Weighing in at a mere 53 lbs."

53 lbs sure isn't my idea of portability.

My idea of portability is speakers that weigh 23 lbs and maybe a mixer that weighs just a couple pounds, and I've got that with the JBL Eon 10 G2's when I decide to use the Behringer UB802 mixer which does give them more headroom if desired.
