Hello all:
I saw this on the web, and thought it to be a bit of a stretch that this design could compete with the Lab Sub. What class of design is this?
How realistic are these stats? BTW-who is Bill Fitzmaurice was he connected to a major speaker company at one time?

Just a few thoughts here...
From what I've seen, Bill has done a good deal of building and design, and has experience with a fair range of professional offerings. He does post some basic measurements as shown in the link provided.
The posted graph does offer an interesting comparison, and it further clarifies why many of us initially involved with the LAB sub project suggest not bothering with the LAB if you are going to be running only a single box outside. In the graph, we have only one snapshot of a comparison. I expect that in comparing more boxes and including excursion and power limited output, the comparison would shift drastically. Of course the Tuba 30 is a bit less expensive, and also smaller in total volume. Personally I see some issues with transporting a 30" cube, as doorways and corners can make for some rather tight manuvering. I tend to prefer at least one shorter dimension. The dimensions might be just fine for many though.
In particular, I would expect the LAB sub's low frequency response to change much more with 2 or more boxes packed together. Of course this is obviously a benfit of the Tuba 30 in that it is optomized more for single box use. I would think anyone with 4 LABs and more than 4kW of power would have no feelings of inadequacy in any such comparison, and I'm sure that those with Tuba 30s are quite impressed with this sort of output from a single 12".
