What size room are the KLH Kendall 2B and B&W 607 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.)
In the following sections, we will get into more detail in order to better understand how the KLH Kendall 2B and B&W 607 S3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Kendall 2B features a 1" Hard-Dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2500 HZ. On the other hand, the 607 S3 features a 1" Titanium Decoupled Double Dome Titanium Tweeter and 1 x 5" Continuum Woofer .
Frequency Response
Kendall 2B has a frequency range of 55-20k Hz whereas 607 S3 has a frequency range of 52-28k Hz. With a minimum frequency of 52Hz, the 607 S3 can go slightly deeper then the Kendall 2B's min frequency of 55Hz.
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 Bookshelf class in our database.

High Frequency
Bookshelf 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
Kendall 2B and 607 S3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Kendall 2B sensitivity is rated at 86 dB and the 607 S3's is at 84 dB. This 2 dB difference makes the KLH Kendall 2B 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.
Kendall 2B can handle a max power of 200 watts RMS from the amp the whereas 607 S3 has a max power handling value of 100 watts RMS, 100 watts less than the Kendall 2B.
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 Kendall 2B and 607 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
KLH Kendall 2B's 5-way 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 Kendall 2B 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 KLH Kendall 2B's and B&W 607 S3's external dimensions. KLH Kendall 2B has external dimensions of 337.0 x 197.0 x 216.0mm ( 13-1/4inch x 7-3/4inch x 8-1/2inch ) 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 31mm narrower and 37mm shorter than KLH Kendall 2B but it is also 19mm deeper.
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 KLH Kendall 2B is approximately 425.5cm2 / 66.0inch2 and base area of the B&W 607 S3 is approximately 390.1cm2 / 60.5inch2. The Kendall 2B requires 9% more surface area than the 607 S3 which gives it a small disadvantage 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 KLH Kendall 2B weighs 5.91kg / 13lbs and the B&W 607 S3 weighs 4.65kg / 10.2lbs. This makes the Kendall 2B 27% heavier than the 607 S3.
Here is a comparison of how Kendall 2B and 607 S3's weights compare with the average, max and min weights in Passive Bookshelf class.
