In this review, we will be comparing Model Three and S 801, two Passive Bookshelf speakers from KLH and Jamo. Let's have a brief look at the main features
of KLH Model Three and Jamo S 801 first before getting into our more
detailed comparison.
What size room are the KLH Model Three and Jamo S 801 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 KLH Model Three and Jamo S 801 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
Both Model Three and S 801 are 2-way speakers. Model Three features a 1" Aluminum Tweeter and 1 x 8" Pulp-Paper Cone Woofer with a Crossover frequency at 1600Hz. On the other hand, the S 801 features a 1" Soft-Dome Tweeter and 1 x 4" Aluminized Polyfiber Woofer .
Frequency Response
Model Three has a frequency range of 46-20k Hz whereas S 801 has a frequency range of 76-26k Hz. With a minimum frequency of 46Hz, the Model Three can go significantly deeper on the low side and provide stronger bass compared to the S 801's min frequency of 76Hz.
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.

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
Model Three is a 6 ohms speaker compared to the S 801 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Model Three sensitivity is rated at 88 dB and the S 801's is rated at 85 dB. This 3 dB difference makes the KLH Model Three a more sensitive speaker compared to Jamo S 801, 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.
Model Three can handle a max power of 150 watts RMS from the amp the whereas S 801 has a max power handling value of 60 watts RMS, 90 watts less than the Model Three.
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
Model Three features Post type posts and S 801 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

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 Model Three's and Jamo S 801's external dimensions. KLH Model Three has external dimensions of 482.0 x 311.0 x 267.0mm ( 19.0 x 12.25 x 10.5inch) whereas Jamo S 801 has external dimensions of 285.0 x 156.0 x 163.0mm ( 11.2 x 6.1 x 6.4inch) .
KLH Model Three is clearly the larger of the two speakers. Its body is 155mm wider, 197mm taller and 104mm deeper than Jamo S 801.
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 Model Three is approximately 830.4cm2 / 128.7inch2 and base area of the Jamo S 801 is approximately 254.3cm2 / 39.4inch2. The Model Three requires 227% more surface area than the S 801 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 Model Three weighs 13.20kg / 29lbs and the Jamo S 801 weighs 2.70kg / 5.9lbs. This makes the Model Three 389% heavier than the S 801.
Here is a comparison of how Model Three and S 801's weights compare with the average, max and min weights in Passive Bookshelf class.
