Samsung HT-E6730W Home Theater System HT Labs Measures

HT Labs Measures

Two channels driven continuously into 8-ohm loads:
0.2% distortion at 46.0 watts
1% distortion at 60.1 watts

Two channels driven into 4-ohm loads:
0.2% distortion at 75.1 watts
1% distortion at 80.8 watts

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the L/R (purple trace) and subwoofer (blue trace). The passive loudspeaker was measured at a distance of 1 meter with a 2.83-volt input.

The L/R’s listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.56/–2.43 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 121 Hz, and the –6-dB point is at 113 Hz. Impedance reaches a minimum of 5.77 ohms at 288 Hz and a phase angle of –36.39 degrees at 6.9 kHz. Sensitivity averages 84 dB from 500 Hz to 2 kHz.

The subwoofer’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3-dB point is at 58 Hz and the –6-dB point is at 53 Hz. The upper –3-dB point is at 101 Hz.

Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –75.34 dB left to right and –78.58 dB right to left. THD+N from the amplifier was less than 0.077 percent at 1 kHz when driving 2.83 volts into an 8-ohm load. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –87.70 dBrA.—MJP

Video Test Bench
The Samsung system’s player/AVR section was tested in two ways: first with its own built-in player and second by driving one of its HDMI inputs with an outboard HDMI source—in this case another Blu-ray player. It passed all of our tests in both instances. The only minor quirk was that with its own player it broke lock with each pass of our 2:2 HD loop but immediately restored it, whereas with an external player, it held the lock on multiple passes. This should have no significance in normal use.—TJN

What kind of room correction does this system use? Is it a parametric equalizer? A graphic equalizer with fixed bands? In any case, unless you're fortunate enough to be sitting at equal distances from each speaker this system probably sounds like crap. The system's room correction is probably a joke and likely doesn't correct anything. Distance settings alone or in combination with room correction that only operates in the frequency domain won't fix imaging problems caused by sitting off center.
