In this review, we will be comparing Model Five and R-625FA, two Passive Floor-standing speakers from KLH and Klipsch. Let's have a brief look at the main features
of KLH Model Five and Klipsch R-625FA first before getting into our more
detailed comparison.
What size room are the KLH Model Five and Klipsch R-625FA 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 Five and Klipsch R-625FA 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 Model Five is a 3-way design whereas the R-625FA 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.

Model Five features a 1" aluminum Hard-Dome Tweeter , a 4" Midrange and 1 x 10" Pulp-Paper Woofer with a Crossover frequency at 380Hz and 2850Hz. On the other hand, the R-625FA features a 1" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
Model Five has a frequency range of 42-20k Hz whereas R-625FA has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-625FA can go slightly deeper then the Model Five's min frequency of 42Hz.
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
Model Five is a 6 ohms speaker compared to the R-625FA which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Model Five sensitivity is rated at 90.5 dB and the R-625FA's is rated at 96 dB. This 5 dB difference makes the Klipsch R-625FA a more sensitive speaker compared to KLH Model Five, 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 Five can handle a max power of 200 watts RMS from the amp the whereas R-625FA has a max power handling value of 100 watts RMS, 100 watts less than the Model Five.
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 Five features Post type posts and R-625FA 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 Five's and Klipsch R-625FA's external dimensions. KLH Model Five has external dimensions of 660.0 x 350.0 x 292.0mm ( 34-1/4 x 13-3/4 x 13inch) whereas Klipsch R-625FA has external dimensions of 1021.0 x 239.0 x 426.0mm ( 40-3/16 x 9-3/8 x 16-3/4inch) .
KLH Model Five is 361mm shorter and 134mm less deeper than Klipsch R-625FA but it is also 111mm wider.
Below you can see the front view size comparison of KLH Model Five and Klipsch R-625FA 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 KLH Model Five is approximately 1022.0cm2 / 158.4inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The Model Five requires 0% more surface area than the R-625FA 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 Five weighs 20.00kg / 44lbs and the Klipsch R-625FA weighs 22.20kg / 48.8lbs. This makes the R-625FA 11% heavier than the Model Five.
Here is a comparison of how Model Five and R-625FA's weights compare with the average, max and min weights in Passive Floor-standing class.
