TECHNICAL SPECIFICATIONS

System
3 way floorstanding, paralaminar “stealth ultraflex” vented loudspeaker.

Cabinet
Enhanced “Lyre” shape design, progressive thickness triple curvature cabinet walls damped spread resonance spectrum system. Solid walnut vertical clamps.

Tweeter
Sonus faber “Arrow Point” DAD (Damped Apex Dome, synthesis of the classic dome and ring transducer) 29XTR2. A Sonus faber designed 29 mm moving coil driver. The ultra dynamic linearity is given by the new Neodymium motor system.

Midrange
Sonus faber M8XTR. A Sonus faber designed 80 mm ultra dynamic linearity midwoofer. CCAW wire is used on a controlled “eddy current free” voice coil. The dynamically linear magnetic field motor has a focused field geometry. A special custom diaphragm is made with a blend of traditional cellulose pulp, kapok, kenaf and other natural fibers, developed according to the most natural sound. To further inhibit any residual cone coloration we are using a transparent viscous surface damping coating. A special coaxial anti-compressor is used, designed to remove cavity resonance and distortions.

Woofers
Sonus faber W15XTR. A totally Sonus faber designed 150 mm ultra dynamic linearity woofer. CCAW wire is used on a composite former “eddy current free” voice coil. The dynamically linear magnetic field motor incorporates triple Kellog/Goeller rings. A special custom diaphragm is made with a real time air dried non pressed blend of traditional cellulose pulp, kapok, kenaf and other natural fibers, developed according to the most natural sound. To further inhibit any residual cone coloration we are using a transparent viscous surface damping coating.

Cross-over
Non-resonant “progressive slope” design, optimized amplitude/phase response for optimal space/time performance. “Paracross topology” on both tweeter hi-pass and midrange band pass, cross-over points 250 Hz - 2.500 Hz. Highest quality components are used including Mundorf Evo Oil capacitors and Jantzen inductors.

Frequency response
50 Hz – 30.000 Hz, tuning port included.

Sensitivity
88 dB SPL (2.83 V/1m). 

Nominal impedance 
4 ohm.

Suggested amplifier power output 
50W – 300W, without clipping.

Long-term maximum input voltage (iec-268-5)
22V rms.

Dimensions 
9.1 x 25.6 x 13.9 in / 230 x 649 x 353 mm (HxWxD).

Optional dedicated stand
17.5 x 17.25 x 12.25 in / 443 x 438 x 310 mm (HxWxD).

Weight
37.5 lbs / 17 kg - net weight
