Very interesting speaker design (the "hidden woofer" trick)

This Genelec 8351 is quite interesting, at least from my point of view as a loudspeaker engineer. There is a tweeter in the center, concentric with a midrange cone that appears to be surround-less. At least, no conventional surround, the edge seems terminated to the surface. The surface is all a giant waveguide for directivity. And the woofer is actually inside, with the bass energy propagating out through the controlled slots top and bottom. The whole deal can network together with others to make a system that can calibrate itself and adjust to the listening environment.

By the way, you heard it here first: the future revolution in home sound will be micro-arrays, controlled by DSP to give (*fairly*) even response throughout the room…tell you more in another thread.
