Trenner & Friedl Osiris loudspeaker
The Osiris's eye-catching 10-degree rearward slope gives it a windswept look recalling to my crusty memory the "blown away guy" from Maxell's print and television advertisements of the 1980s. The Osiris's proportions—it measures 33.5" high by 14.25" wide by 14.56" deep—reveal it for what it is: a small floorstander that should fit well in most living rooms.
"The port is a hybrid between a classic bass reflex design and a horn," Friedl explained. "We use the floor as part of the system, so the alignment is not so dependent on the room. It's a very efficient solution. But much smaller than a real horn construction."
Description: Coaxial-driver, vented, floorstanding loudspeaker. Drive units: 6.5" paper cone woofer, coated with oil lacquer. 1" horn-loaded coaxial compression tweeter driver with titanium diaphragm. Frequency range: 38Hz–30kHz. Sensitivity: 88.7dB/2.83V/1m. Nominal impedance: 8 ohms.
Dimensions: 33.50" (850mm) H by 14.25" (360mm) W by 14.56" (370mm) D. Weight: 55lb (25kg).
Finishes: Walnut natural, walnut amaranth, walnut blazed.
Trenner & Friedl Osiris, anechoic response on tweeter axis at 50", averaged across 30° horizontal window and corrected for microphone response, with the nearfield woofer (blue) and vent (red) responses and their complex sum (black) respectively plotted below 270Hz, 1kHz, and 270Hz.

Trenner & Friedl Osiris loudspeaker
Austrian loudspeaker manufacturer Trenner & Friedl has a thing for coaxial drivers. They're used in at least three of the company's eight loudspeaker models, including the diminutive Sun bookshelf speaker and the large floorstanding Taliesin. In these models, T&F eschew more conventional stacked...
