Imaging tweeter in the middle of woofer matrix.

[mashaffer]

What are the imaging issues with placing a tweeter in the middle of a square woofer matrix.

They did it in the 1960s with some flat(ish) baffle designs. Don't remember how it sounded.

Seems like a good way to get the tweeter close to the woofer surface, but what it does to lobing, I don't know. Someone here will know.

from the Donald North patent:
The geometric relationship between the woofers as shown in the embodiment 300 of FIG. 3 results in a sound field which maximizes the energy lobes directed toward the listener and minimizes the severity of the energy lobes directed towards reflecting surfaces and room boundaries. The embodiment reduces the severity of the magnitude of the side lobes through an advantageous arrangement of transducers, which minimizes the alignment of transducers along horizontal or vertical axes. Alignment of transducers along an axis results in severe standing wave interference of the sound waves from the transducers in alignment. As previously mentioned, a feature of the embodiment of 300 is that no two centers of the woofers align either horizontally or vertically.
