Sonus Faber Elipsa Loudspeakers, Graphite, TRADE-IN

Some words on their technicalities from Stereophile:

"The Elipsa is a three-way design. A 1" ring-radiator tweeter sits 36" from the floor, mounted very close above a 6" pulp-cone midrange driver, the diaphragm of which has a concave dustcap to continue the smooth profile. The midrange driver handles a wide range, 250Hz –2.3kHz, and is acoustically loaded within its own elliptically shaped subenclosure, this vented to the speaker's rear with a 2.25"-diameter port. Whereas the Cremona has twin 6" woofers, the Elipsa uses a single 10" woofer, the cone of which is formed from an alloy of magnesium and aluminum. This driver is acoustically loaded by two 3"-diameter flared ports on the cabinet rear and, rather than a dustcap, has a stationary metal phase plug on the front of its central pole piece.

The crossover is specified as using second-order slopes. Electrical connection is via a single pair of high-quality binding posts at the base of the cabinet rear, beneath the lowest of the three ports and set, like them, on a leather-covered panel. The black metal bottom plate can be fitted with spikes of differing lengths front and back to allow the speaker to be raked back."
