I know that I have discussed this in several threads but thought I would provide a visual example of this as I am finishing up maintenance on one of my own scalable systems. They are used in anything from 3 over 3 per side on top of subs to flying a distributed system around an arena, to a bunch of high quality speaker on sticks depending on need. All are 10" x 2 way with ATM Flyware and speaker butt plugs on every cabinet. It was a cabinet I designed 17 years ago as a tourable installation type product for conference and convention work as well as live theatre. These cabinets earn a good living every year and have required almost nothing in repairs over the 15 years. Plenty of life left in them so they will continue to earn money without ongoing costs.
