OK, maybe $150,000 is a bit much for a pair of speakers, but the price does include installation and you don't need to buy a subwoofer

French speaker maker Cabasse has introduced La Sphere, apparently the world’s only 4-way coaxial speaker system. All four drivers, are arranged in a line inside a spherical 27.6-inch enclosure intended to enhance rigidity, eliminate internal standing waves and eliminate diffraction effects.

Frequency response with the 22” honeycomb dome subwoofer driver is said to extend to below 20 HZ, so you won't need to pay extra for a subwoofer. However, if you want to do five channels for an all-sphere home theater system, figure on spending $375,000, plus sales tax, of course.

For nearly 400 grand, they better cook supper, wash the dishes and sing you to sleep. CLICK for more. (This is a preview, not a review.)
