In this review, we will be comparing 702 S3 and RF-7 III, two Passive Floor-standing speakers from Bowers Wilkins and Klipsch. Let's have a brief look at the main features
of B&W 702 S3 and Klipsch RF-7 III first before getting into our more
detailed comparison.
What size room are the B&W 702 S3 and Klipsch RF-7 III 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 B&W 702 S3 and Klipsch RF-7 III 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 702 S3 is a 3-way design whereas the RF-7 III is a 2-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.

702 S3 features a 1" Tweeter , a 6" Midrange and 3 x 6.5" Aerofoil Woofer . On the other hand, the RF-7 III features a 1.75" titanium dome Tweeter and 2 x 10" Cerametallic Woofer with a Crossover frequency at 1300Hz.
Frequency Response
702 S3 has a frequency range of 46-28k Hz whereas RF-7 III has a frequency range of 32-25k Hz. With a minimum frequency of 32Hz, the RF-7 III 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.

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 RF-7 III 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 RF-7 III's is at 100 dB. This 12 dB difference makes the Klipsch RF-7 III a more sensitive speaker compared to B&W 702 S3, hence will play louder with the same amount of watts.

Floor-standing Speakers
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 RF-7 III has a max power handling value of 250 watts RMS, 50 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 RF-7 III 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
Klipsch RF-7 III's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both 702 S3 and RF-7 III 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 RF-7 III'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 RF-7 III has external dimensions of 1247.0 x 355.0 x 456.0mm ( 49-1/16 x 13-15/16 x 17-15/16inch) .
Klipsch RF-7 III is clearly the larger of the two speakers. Its body is 163mm wider, 109mm taller and 65mm deeper than B&W 702 S3.
Below you can see the front view size comparison of B&W 702 S3 and Klipsch RF-7 III in scale.

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 RF-7 III is approximately 1618.8cm2 / 250.9inch2. The 702 S3 requires 54% less surface area than the RF-7 III 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 B&W 702 S3 weighs 33.46kg / 73.6lbs and the Klipsch RF-7 III weighs 44.10kg / 97lbs. This makes the RF-7 III 32% heavier than the 702 S3.
Here is a comparison of how 702 S3 and RF-7 III's weights compare with the average, max and min weights in Passive Floor-standing class.
