Scuba Dog, you should use 2 6200 Streams. For the wavebox, expect a 1/2- 3/4" high wave, the overflow should be just the normal built in type overflows. Technically you should need two waveboxes. I would start with one and if you need the second to boost wave height you will need the dummy wavebox without controller as they have to share the controller.
RGibson, at any given time we have a dozen or more products in the works. Which ones will make it past the drawing board and become big is hard to say, we have lots of prototyes that never make it because they are too expensive, too hard to build or the volume just isn't their to make it profitable, we figure we have to sell at least 3000 of something to pay for the development in most cases. We never thought we would top the Stream and now we don't know how we can top the Wavebox but I figure we will. We have a lot of experiments going but they are filter systems and components, not flow devices, I think we have reached the practical limit of currently applicable technology to flow.
Marc, Did Champion demo the Wavebox? They never called me for instructions so I didn't know if they figured it out. At the time I was planning a trip to Germany so I opted out on going to MACNA. The magnet holder should be able to hold a wavebox. While it is not impossible, the wavebox pump is a hybrid between a 6200 and a 6100 and it requires a special controller. I don't believe any pumpless unit will be offered. Besides, you still need the Streams with the wavebox.
