High Frequency
Floor-standing 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
703 S2 and HTM71 S2 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.

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.
703 S2 and HTM71 S2 has the same power range of 30-200 watts.
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
Both 703 S2 and HTM71 S2 features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 703 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 703 S2 and HTM71 S2 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 B&W 703 S2's and BW HTM71 S2's external dimensions. B&W 703 S2 has external dimensions of 1025.0 x 200.0 x 321.0mm ( 40.4-inch x 12-11/16-inch x 12.6-inch) 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) .
BW HTM71 S2 is 797mm shorter and 19mm less deeper than B&W 703 S2 but it is also 391mm 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 B&W 703 S2 is approximately 642.0cm2 / 99.5inch2 and base area of the BW HTM71 S2 is approximately 1784.8cm2 / 276.6inch2. The 703 S2 requires 64% less surface area than the HTM71 S2 which gives it a small advantage on placement in tight spaces.
