SONUS FABER VENERE 3.0

摘要

Sonus faber doesn't specify sensitivity for any of the Venere range but our pink noise figure of 86.9dB for the 3.0 indicates that it is slightly below average for a floorstander of this size. In part this reflects the fact that the largest of the Venere models presents a fairly friendly amplifier load. Although the impedance modulus drops to a minimum of 3.4ohm at 94Hz, consistent with a 4ohm nominal rating, phase angles are well enough controlled for the minimum EPDR (equivalent peak dissipation resistance) to be 2.1 ohm at 130Hz and the same again at 887Hz - not as challenging as some competitors. Frequency response [Graph 1, below] was measured on the axis of the midrange driver, as on the tweeter axis there proved to be a wide depression in presence band output. This means that to hear the most neutral tonal balance from the Venere 3.0 may require a lower than usual seating position, although the adjustable base does provide a slight tilt. Even on the axis of the midrange driver the response is clearly concave in trend, so the tonal balance is likely to be on the warm side of neutral and the stereo image a little recessed. But the response errors, over the range 200Hz-20kHz, are modest at ±3.SdB and ±3.0dB respectively. Pair matching error, over the same frequency range, is a little high, though, at ±1.7dB with quite large, sustained disparity in the two octaves from 1 kHz to 4kHz. Bass extension of 58Hz (-6dB re. 200Hz) is typical for this type of speaker but ultrasonic output declines rapidly above 20kHz. The cumulative spectral decay waterfall [Graph 2] shows fast decay across much of the audible spectrum and little sign of ridges indicating cone breakup.
