HTM6 S3 features a 1" Titanium Decoupled Double Dome Tweeter and 2 x 5" Continuum Woofer . On the other hand, the 607 S3 features a 1" Titanium Decoupled Double Dome Titanium Tweeter and 1 x 5" Continuum Woofer .
Frequency Response
HTM6 S3 has a frequency range of 72-28k Hz whereas 607 S3 has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 607 S3 can go significantly deeper on the low side and provide stronger bass compared to 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 607 S3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. HTM6 S3 sensitivity is rated at 87 dB and the 607 S3's is at 84 dB. This 3 dB difference makes the BW HTM6 S3 a more sensitive speaker compared to B&W 607 S3, 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.
HTM6 S3 can handle a max power of 120 watts RMS from the amp the whereas 607 S3 has a max power handling value of 100 watts RMS, 20 watts less than the HTM6 S3.
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 607 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 607 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both HTM6 S3 and 607 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
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 B&W 607 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 607 S3 has external dimensions of 300.0 x 166.0 x 235.0mm ( 11.8 x 6.5 x 9.3inch) .
B&W 607 S3 is 314mm narrower and 48mm less deeper than BW HTM6 S3 but it is also 140mm taller.
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 607 S3 is approximately 390.1cm2 / 60.5inch2. The HTM6 S3 requires 248% more surface area than the 607 S3 which gives it a small disadvantage on placement in tight spaces.
