Summary
The Phantom is a highly eye-catching and expensive speaker system (US$2,000 per speaker), that promises to replace full-sized speakers and deliver equivalent sound power in a tiny package, while still retaining good sonic quality. To achieve that, the speaker had to be redesigned from the ground-up with 1,527 engineering parts and is marketed as the "most dense sound in the world" considering its audio output for its physical size. You can even daisy-chain multiple Phantom speakers to fill a rather large space.
