What size room are the BW HTM6 S3 and B&W HTM72 S3 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers

HTM6 S3 features a 1" Titanium Decoupled Double Dome Tweeter and 2 x 5" Continuum Woofer. On the other hand, the HTM72 S3 features a 1" Decoupled Carbon Decoupled Soft-Dome Tweeter and 2 x 5" Continuum cone Woofer.
Frequency Response
HTM6 S3 has a frequency range of 72-28k Hz whereas HTM72 S3 has a frequency range of 70-28k Hz. With a minimum frequency of 70Hz, the HTM72 S3 can go slightly deeper then the HTM6 S3's min frequency of 72Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
HTM6 S3 and HTM72 S3 have the same Impedance of 8 ohms and their sensitivity is also same at 87 dB.
Sensitivity
Center Channel Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
HTM6 S3 and HTM72 S3 have the same power range of 30-120 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both HTM6 S3 and HTM72 S3 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
B&W HTM72 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both HTM6 S3 and HTM72 S3 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
The size of a speaker can sometimes be 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 B&W HTM72 S3'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 B&W HTM72 S3 has external dimensions of 166.0 x 478.0 x 304.0mm (6-1/2inch x 18-13/16inch x 11-15/16inch).
BW HTM6 S3 is 6mm shorter and 21mm less deeper than B&W HTM72 S3 but it is also 2mm wider.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Near-identical footprints. B&W HTM72 S3 is 21mm deeper, so it stands that much further out from the wall.
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 B&W HTM72 S3 is approximately 1453.1cm2 / 225.2inch2. The HTM6 S3 requires 7% less surface area than the HTM72 S3 which gives it a small advantage 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 B&W HTM72 S3 weighs 9.70kg / 21.3lbs. This makes the HTM72 S3 26% heavier than the HTM6 S3.
Here is a comparison of how HTM6 S3 and HTM72 S3's weights compare with the average, max and min weights in Passive Center Channel class.

These sit in different price classes - B&W HTM72 S3 costs roughly 1.7x what BW HTM6 S3 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (72Hz vs 70Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (87dB vs 87dB) - both want much the same power. |
| Headroom | evenly matched | Similar power handling (120W vs 120W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | BW HTM6 S3 : bi-amping; B&W HTM72 S3: bi-amping. B&W HTM72 S3 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | A | BW HTM6 S3 is cheaper - $899 against $1,499, about 40% less; arguably a different class. |
A BW HTM6 S3 B B&W HTM72 S3
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. Think about the whole system, not just the speakers: the roughly $600 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
