Sinclair Audio Brighton 50B Speaker System HT Labs Measures

HT Labs Measures

Satellite Sensitivity: 87.5 dB from 500 Hz to 2 kHz

Center Sensitivity: 90 dB from 500 Hz to 2 kHz

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the 50B satellite (purple trace), 25CC center channel (green trace), and 310S 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 50B’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.12/–2.88 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 78 Hz, and the –6-dB point is at 56 Hz. Impedance reaches a minimum of 6.23 ohms at 232 Hz and a phase angle of –38.84 degrees at 137 Hz.

The 25CC’s listening-window response measures +2.90/–2.45 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +3.13/–4.24 dB from 200 Hz to 10 kHz. The –3-dB point is at 63 Hz, and the –6-dB point is at 47 Hz. Impedance reaches a minimum of 5.99 ohms at 251 Hz and a phase angle of –35.44 degrees at 131 Hz.

The 310S’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 36 Hz and the –6-dB point is at 34 Hz. The upper –3-dB point is at 148 Hz using the LFE input.—MJP

These are identical to the Roth speakers sold in the UK. The Roth OLi 20 and the Sinclair 50B, and the OLi 10s and the 40Bs look to be exactly the same. So who actually designed them? The Roths get pretty good reviews over here in the UK.
