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
HTM71 S3 and HTM71 S2 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.
Sensitivity

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.
HTM71 S3 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 HTM71 S3 and HTM71 S2 features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W HTM71 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both HTM71 S3 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 HTM71 S3's and BW HTM71 S2's external dimensions. B&W HTM71 S3 has external dimensions of 235.0 x 629.0 x 356.0mm ( 9-1/4inch x 24-3/4inch x 14inch ) 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) .
B&W HTM71 S3 is clearly the larger of the two speakers. Its body is 38mm wider, 7mm taller and 54mm deeper than BW HTM71 S2.
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 HTM71 S3 is approximately 2239.2cm2 / 347.1inch2 and base area of the BW HTM71 S2 is approximately 1784.8cm2 / 276.6inch2. The HTM71 S3 requires 25% more surface area than the HTM71 S2 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The B&W HTM71 S3 weighs 17.50kg / 38.5lbs and the BW HTM71 S2 weighs 18.05kg / 39.7lbs. This makes the HTM71 S2 3% heavier than the HTM71 S3.
Here is a comparison of how HTM71 S3 and HTM71 S2's weights compare with the average, max and min weights in Passive Center Channel class.
