Monitor Audio Gold GX50 Speaker System HT Labs Measures

HT Labs Measures

Satellite Sensitivity: 87.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 88 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (em- ploying close-miking of all woofers) frequency response of the GX50 satellite (purple trace), GXC-150 center channel (green trace), and GXW-15 subwoofer (blue trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The GX50’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.17/–1.95 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 59 Hz, and the –6-dB point is at 53 Hz. Impedance reaches a minimum of 4.85 ohms at 216 Hz and a phase angle of –53.30 degrees at 108 Hz.

The GXC-150’s listening-window response measures +1.29/–1.36 dB from 200 Hz to 10 kHz. An average of axial and +/–15- degree horizontal responses measures +1.84/–1.92 dB from 200 Hz to 10 kHz. The –3-dB point is at 72 Hz, and the –6-dB point is at 55 Hz. Impedance reaches a min- imum of 4.94 ohms at 190 Hz and a phase angle of –49.74 degrees at 84 Hz.

The GXW-15’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 39 Hz and the –6-dB point is at 29 Hz. The upper –3-dB point is at 190 Hz using the LFE input and the EQ set to Off.—MJP

Was really looking for a Gx50 review and here we go!
Just wondering about male and female voices: how do they sound ?

Thanks.

Glad we could provide a product review you were looking for! In the review, Mark comments on vocals in three different examples: two movies (The Covenant, Star Trek: Insurrection) and one piece of music (Dave Edmunds). He rarely comments on female and male vocals specifically unless something is amiss with either one (for example, if female vocals are particularly boomy), which wasn't the case here.

Hi Scott, thank you for your comment. You are perfectly right: vocals were commented for both movies (where clarity and resolution could be appreciated) and music (where, for this live piece of Rock music, I understand that at high volume the speakers turned to be a bit too much revealing or even harsh with respect to the singer's voice).

Good to know that in general there was nothing bad to mention about female & male vocals.

Great review!
