What size room are the BW HTM72 S2 and B&W 703 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:

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.)
In the following sections, we will get into more detail in order to better understand how the BW HTM72 S2 and B&W 703 S2 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that HTM72 S2 is a 2-way design whereas the 703 S2 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

HTM72 S2 features a 1" Decoupled Carbon Dome Tweeter and 2 x 5" Continuum Woofer . On the other hand, the 703 S2 features a 1" Tweeter , a 6" Midrange and 2 x 6.5" Aerofoil Woofer .
Frequency Response
HTM72 S2 has a frequency range of 70-28k Hz whereas 703 S2 has a frequency range of 46-28k Hz. With a minimum frequency of 46Hz, the 703 S2 can go significantly deeper on the low side and provide stronger bass compared to the HTM72 S2's min frequency of 70Hz.
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.

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
HTM72 S2 and 703 S2 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. HTM72 S2 sensitivity is rated at 87 dB and the 703 S2's is at 89 dB. This 2 dB difference makes the B&W 703 S2 a more sensitive speaker compared to BW HTM72 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.
HTM72 S2 can handle a max power of 200 watts RMS from the amp the whereas HTM72 S2 has a max power handling value of 120 watts RMS , 80 watts less than the 703 S2.
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 HTM72 S2 and 703 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 HTM72 S2 and 703 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 HTM72 S2's and B&W 703 S2's external dimensions. 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) whereas 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) .
BW HTM72 S2 is 856mm shorter and 43mm less deeper than B&W 703 S2 but it is also 282mm 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 BW HTM72 S2 is approximately 1340.0cm2 / 207.7inch2 and base area of the B&W 703 S2 is approximately 642.0cm2 / 99.5inch2. The HTM72 S2 requires 109% more surface area than the 703 S2 which gives it a small disadvantage on placement in tight spaces.
