It's called a soundboard cutoff bar. (There are other names, but that is the one I use). It is not located in the bass section, it is located in the front left corner of the soundboard area. The bass section is toward the back of the piano in the area around the bass bridge. The cutoff bar, along with the filler block (which I call the "fish" due to its shape) used along the inner rim up in the treble area, limit the size of the soundboard, making it more function somewhat more efficiently. Much has been written about these soundboard shaping devices on Pianotech. You might check the archives. As well, I've been discussing them and illustrating them in my classes and seminars for some thirty years now. I realize these are generally presented some distance from your home, still, if you find yourself in an area where one is being presented you might find it worthwhile.

Why is there a cutout in the bass section? I believe Terry Farrell posted some pictures of a sound board he had made with a similar shape a while back. Can someone please explain the unusual shape. Inquiring minds would like to know if its not too much trouble.

I have all of the photographs of this piano labeled "Bosendorfer" but I could be wrong. I did this piano some fifteen years ago. I don't have a picture of the finished piano but I've attached one with the soundboard being glued in so you can see the shape. As I recall the piano was pre-1880s. I could probably find the build date with some searching.
