Sensitivity: 86 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Solus Entré II Speaker System (purple trace). The passive loudspeaker was measured with grille at a distance of 1 meter with a 2.83-volt input.

The Entré II Speaker System’s listening-window response (a five-point average of axial and ±15º horizontal and vertical responses) measures +2.64/–4.20 dB from 200 Hz to 10 kHz. An average of axial and ±15º horizontal responses measures +2.83/–3.97 dB from 200 Hz to 10 kHz. The –3-dB point is at 69 Hz, and the –6-dB point is at 38 Hz. Impedance reaches a minimum of 5.88 ohms at 230 Hz and a phase angle of –47.49º at 2.5 kHz.—MJP

Editor's Note: Readers focusing on the Entré II's –3 dB down point at 69 Hz may think erroneously that it fails to deliver on its promise of delivering real bass down to below 40 Hz. However, that –3 dB is relative to the speaker's somewhat elevated midrange bump. The curve shows substantial and sustained bass output from 80 Hz down to 40 Hz before the speaker really begins dropping off rapidly, borne out by the –6 dB point at 38 Hz, though depending on room acoustics, its deepest bass might have less subjective impact due to the difference in level.—RS
