In the strictest sense this is not true.
Yes, but I'll stand by that in the context of the discussion......durability meaning the abuse taken by the surface of the panel which is the same regardless of thickness and that the bracing of the box creates the sturdiness.
I'd say it still depends on the application. For permanently placed cabs, cabs that are babied, or cabs with line-x, 1/2" is always enough. There is no danger of losing wood mass from wear and tear with those. If your cabs get thrown around by roadies, subjected to road rash, etc, 1/2" will start to look irreparably ratty before 3/4". For the weight savings, it's worth it most of the time.
It's just worth considering that words like "sturdy" and "durable" are subjective. My subs that are made from 3/4 cabinet grade ply with pocket screws and PL glue stand up to road wear WAY better than the DR200s made from auraco 1/2" did. Those were getting ratty very quickly so I refinished them and put them in an install (that customer got a crazy deal. Still kind of regret it). Some of that is the grade of ply, but some of it is the thickness.
I'm sure we can agree that with these designs, it is critical to keep the internals at 1/2" ply. There is no benefit to anything else. There really should be no problem, though, with anyone making the outer shell of anything they want, with the caveat that from a performance perspective, 1/2" is sufficient. The downside is weight. The upside is the possibility of greater durability if needed. Each builder should weigh the benefits, make a decision, and not be castigated for it.
99% of the time, things that aren't already being done aren't being done because they don't work. The other 1% is split evenly between fools and geniuses.
