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 Bronze 1 features a 1" Dome Tweeter and 1 x 5.5" C-CAM Woofer with a Crossover frequency at 2700Hz.
Frequency Response
Model Three has a frequency range of 46-20k Hz whereas Bronze 1 has a frequency range of 55-30k 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 Bronze 1'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.

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 Bronze 1 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 88 dBdB.

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 Bronze 1 has a max power handling value of 70 watts RMS, 80 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 Bronze 1 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 Monitor Audio Bronze 1'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 Monitor Audio Bronze 1 has external dimensions of 260.0 x 165.0 x 205.0mm ( 10.2 x 6.4 x 8.0inch) .
KLH Model Three is clearly the larger of the two speakers. Its body is 146mm wider, 222mm taller and 62mm deeper than Monitor Audio Bronze 1.
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 Monitor Audio Bronze 1 is approximately 338.3cm2 / 52.4inch2. The Model Three requires 145% more surface area than the Bronze 1 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 Monitor Audio Bronze 1 weighs 3.50kg / 7.7lbs. This makes the Model Three 277% heavier than the Bronze 1.
Here is a comparison of how Model Three and Bronze 1's weights compare with the average, max and min weights in Passive Bookshelf class.
