Carboton's cabinets are made from a composite of carbon fiber and fiberglass-reinforced plastic, which exhibits the right balance of stiffness and damping behavior. Using a monocoque construction technique similar to that of race-car bodies and a curvilinear design, this is said to avoid distortions by preventing external reflections and internal standing waves.
The Maitresse is Carboton's flagship with an 8-inch sandwich-composite woofer, 6.5-inch ceramic midrange, and 1-inch ceramic tweeter in a slender, ported enclosure. The 3-way design achieves a frequency response from 30Hz to 25kHz with a sensitivity of 87dB/W/m.
Similar in appearance, the 2-way Juliet omits the 8-inch woofer, pairing a 6.5-inch aluminum mid/woofer with the same 1-inch ceramic tweeter for a frequency response from 35Hz to 25kHz with a sensitivity of 84dB/W/m.
Neither speaker can reach all way to the bottom of the human hearing range, so Carboton offers the Romeo subwoofer with a 12-inch cellulose-membrane driver in a ported cabinet. Powered by a 400W internal amp, its frequency response reaches from 15 to 155Hz.
Of course, the Carboton speakers carry a hefty price tag$30,850/pair for the Maitresse, $13,160/pair for the Juliet, and $8250 for the Romeo. Actually, I'm surprised that the Maitresse is so much more than the Juliet for only 5Hz lower bass extension and 3dB more sensitivity. Combining a Romeo with a pair of Juliets would be much less expensive than a pair of Maitresses, and the result would likely be a match made in heavenwhich is probably what the company had in mind when it named them.
