In this review, we will be comparing HTM6 S3 and HTM72 S2, two Passive Center Channel speakers by Bowers Wilkins Let's have a brief look at the main features
of BW HTM6 S3 and BW HTM72 S2 first before getting into our more
detailed comparison.
What size room are the BW HTM6 S3 and BW HTM72 S2 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the BW HTM6 S3 and BW HTM72 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

HTM6 S3 features a 1" Titanium Decoupled Double Dome Tweeter and 2 x 5" Continuum Woofer . On the other hand, the HTM72 S2 features a 1" Decoupled Carbon Dome Tweeter and 2 x 5" Continuum Woofer .
Frequency Response
HTM6 S3 has a frequency range of 72-28k Hz whereas HTM72 S2 has a frequency range of 70-28k Hz. With a minimum frequency of 70Hz, the HTM72 S2 can go slightly deeper then the HTM6 S3's min frequency of 72Hz.
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.

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
HTM6 S3 and HTM72 S2 have the same Impedance of 8 ohms and their sensitivity is also same at 87 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.
HTM6 S3 and HTM72 S2 has the same power range of 30-120 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 HTM6 S3 and HTM72 S2 features dual binding post speaker terminals for bi-amping or bi-wiring.
BW HTM6 S3 's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both HTM6 S3 and HTM72 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 BW HTM6 S3 's and BW HTM72 S2's external dimensions. BW HTM6 S3 has external dimensions of 160.0 x 480.0 x 283.0mm ( 6.3 x 18.9 x 11.2inch) whereas BW HTM72 S2 has external dimensions of 169.0 x 482.0 x 278.0mm ( 6-5/8 x 18-15/16 x 10-15/16inch) .
BW HTM6 S3 is 2mm narrower and 9mm shorter than BW HTM72 S2 but it is also 5mm deeper.
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 BW HTM6 S3 is approximately 1358.4cm2 / 210.6inch2 and base area of the BW HTM72 S2 is approximately 1340.0cm2 / 207.7inch2. The HTM6 S3 requires 1% more surface area than the HTM72 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 BW HTM6 S3 weighs 7.70kg / 16.9lbs and the BW HTM72 S2 weighs 9.14kg / 20.1lbs. This makes the HTM72 S2 19% heavier than the HTM6 S3.
Here is a comparison of how HTM6 S3 and HTM72 S2's weights compare with the average, max and min weights in Passive Center Channel class.
