SuperCenter Reference features a " Tweeter and 4 x 5.25" Woofer . On the other hand, the HTM71 S2 features a 1" Decoupled Carbon Dome Tweeter , a 4" Midrange and 2 x 6.5" Aerofoil Profile Woofer .
Frequency Response
SuperCenter Reference has a frequency range of 33-35k Hz whereas HTM71 S2 has a frequency range of 50-28k Hz. With a minimum frequency of 33Hz, the SuperCenter Reference can go significantly deeper on the low side and provide stronger bass compared to the HTM71 S2's min frequency of 50Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Center Channel class in our database.
Low Frequency

High Frequency
Center Channel Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
SuperCenter Reference and HTM71 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. SuperCenter Reference sensitivity is rated at 91 dB and the HTM71 S2's is at 89 dB. This 2 dB difference makes the GoldenEar SC Ref a more sensitive speaker compared to BW HTM71 S2, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
SuperCenter Reference can handle a max power of 350 watts RMS from the amp the whereas HTM71 S2 has a max power handling value of 200 watts RMS, 150 watts less than the SuperCenter Reference.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
HTM71 S2 features Binding post posts which make bi-amping or bi-wiring possible. SuperCenter Reference has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare GoldenEar SC Ref's and BW HTM71 S2's external dimensions. GoldenEar SC Ref has external dimensions of 150.0 x 889.0 x 281.0mm ( 5-7/8 x 35 x 11-1/16inch) whereas BW HTM71 S2 has external dimensions of 228.0 x 591.0 x 302.0mm ( 8-15/16 x 23-1/4 x 11-7/8inch) .
GoldenEar SC Ref is 78mm shorter and 21mm less deeper than BW HTM71 S2 but it is also 298mm wider.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the GoldenEar SC Ref is approximately 2498.1cm2 / 387.2inch2 and base area of the BW HTM71 S2 is approximately 1784.8cm2 / 276.6inch2. The SuperCenter Reference requires 40% more surface area than the HTM71 S2 which gives it a small disadvantage on placement in tight spaces.
