In this review, we will be comparing Model Three and R-41M, two Passive Bookshelf speakers from KLH and Klipsch. Let's have a brief look at the main features of KLH Model Three and Klipsch R-41M first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how KLH Model Three and Klipsch R-41M compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both Model Three and R-41M 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, R-41M features a 1" Tractrix Horn Tweeter and 1 x 4" Copper-spun IMG Woofer with a Crossover frequency at 1730Hz.
Model Three has a frequency range of 46-20k Hz whereas R-41M has a frequency range of 68-21k 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 R-41M's min frequency of 68Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers under Bookshelf class in our database.
Impedance and Sensitivity
Model Three is a 6 ohms speaker compared to R-41M 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 R-41M's is at 90 dB. This 2 dB difference makes Klipsch R-41M a more sensitive speaker compared to KLH Model Three, hence will play louder with the same amount of watts.
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 R-41M has a max power handling value of 50 watts RMS, 100 watts less than the Model Three.
Keep in mind that higher max power handling value doesn't necesssarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impededance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Model Three features Single Gold Plated Binding Posts type posts and R-41M has a Single Gold Plated Binding Posts type posts. None of these speakers feature bi-amping/bi-wiring.
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 Klipsch R-41M'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 Klipsch R-41M has external dimensions of 287.0 x 146.0 x 200.0mm ( 11.2 x 5.7 x 7.8inch) .
KLH Model Three is clearly the larger of the two speakers. Its body is 165mm wider, 195mm taller and 67mm deeper than Klipsch R-41M.
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 Klipsch R-41M is approximately 292.0cm2 / 45.3inch2. The Model Three requires 184% more surface area than the R-41M which gives it a small disadvantage on placement in tight spaces.
