Luis,
I suspect your story is one of bad timing. Tekton is clearly in a growth phase right now. In trying to keep overhead and costs low (The DI is in fact a huge value with far smaller markup than is the industry norm), Eric I'm sure lacks the manpower right now for these special order items.
I love a nice veneer. Eric was upfront with me and told me it would take months. I opted for the "Model T black" and honestly love the way it doesn't draw attention to itself and vanishes in the music.
If your heart is set on veneer, you may be stuck. A shame as the speakers really are special and I think untouchable at the price. More than once I've wondered how Eric has pulled this off with such a small crew--product development, phone calls, new web site, and oh yah, you need to find time to build the speakers too!
Might suggest you give it some time and think it over. I can understand your frustration. I'm sure it's not intentional. Just bad timing.
