I am going to build my son a set of Hi Fi speakers for his birthday. The plan so far is to build the cabinets from MDF & then veneer will be applied over the MDF. I have designed the cabinets to have curved sides & curved top & bottom. I wanted to apply a thick veneer for long term durability and to give me the ability to apply the final curve, as the base cabinet will be laid up using strips of MDF. I wanted to know what’s the maximum thickness veneer I can use? I have read (somewhere?)that veneer shouldn’t be too thick as it causes problems. Also I wasn’t intending on putting any veneer on the inside.

Thick veneer starts behaving like a real piece of wood so seasonal wood movement is the "problem" you're making reference to. When I took my week long veneering course a couple years ago at Rosewood Studio we were told that 1/28 of an inch is pretty much the maximum thickness you should use. I don't know where this data came from exactly and I assume that the wood species and the width of a panel would have some effect on how thick the veneer can be.
I am not sure that a thick veneer will give you better longevity. The abuse normally takes place at the edges so using "normal" veneer thickness with solid wood edging would be a good solution.
I think most people on this forum will tell you that veneering only one side of a panel is a no-no as it will bend the panel.
Thanks for the assistance
The common thicknesses of veneer that are commercially available are 0.6mm and 1.2mm. They both behave entirely like veneer. If you want thicker than that you'll probably have to prepare it yourself, and in that case you could get into a transitional kind of material. It depends on the species of course, but around 3.0mm thick it's going to start behaving more like solid wood than veneer.
