702 S3 features a 1" Tweeter , a 6" Midrange and 3 x 6.5" Aerofoil Woofer . On the other hand, the Forte IV features a 1" titanium-diaphragm compression horn-loaded Tweeter , a 1.75" Midrange and 1 x 12" Fibercomposite Woofer .
Frequency Response
702 S3 has a frequency range of 46-28k Hz whereas Forte IV has a frequency range of 38-20k Hz. With a minimum frequency of 38Hz, the Forte IV can go significantly deeper on the low side and provide stronger bass compared to the 702 S3's min frequency of 46Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing 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
702 S3 and Forte IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 702 S3 sensitivity is rated at 90 dB and the Forte IV's is at 99 dB. This 11 dB difference makes the Klipsch Forte IV a more sensitive speaker compared to B&W 702 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.
702 S3 can handle a max power of 300 watts RMS from the amp the whereas Forte IV has a max power handling value of 100 watts RMS, 200 watts less than the 702 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 702 S3 and Forte IV features dual binding post speaker terminals for bi-amping or bi-wiring.
B&W 702 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 702 S3 and Forte IV 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 702 S3's and Klipsch Forte IV's external dimensions. B&W 702 S3 has external dimensions of 1138.0 x 192.0 x 391.0mm ( 44.8-inch x 7.6-inch x 15.4-inch) whereas Klipsch Forte IV has external dimensions of 909.0 x 423.0 x 331.0mm ( 35-3/4 x 16-5/8 x 13inch) .
Klipsch Forte IV is 229mm shorter and 60mm less deeper than B&W 702 S3 but it is also 231mm 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 B&W 702 S3 is approximately 750.7cm2 / 116.4inch2 and base area of the Klipsch Forte IV is approximately 1400.1cm2 / 217.0inch2. The 702 S3 requires 46% less surface area than the Forte IV which gives it a small advantage on placement in tight spaces.
