Drivers
One of the fundamental differences between these two speakers is that RP-8000F II is a 2-way design whereas the Sonetto III is a 3-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.

RP-8000F II features a 1" titanium Tractrix Horn Tweeter and 2 x 8" Cerametallic cone Woofer with a Crossover frequency at 1630 Hz. On the other hand, the Sonetto III features a 1.15" high definition DAD Dome Tweeter , a 6" Midrange and 2 x 6" aluminum cone Woofer with a Crossover frequency at 220 and 3.250 Hz.
Frequency Response
RP-8000F II has a frequency range of 32-25k Hz whereas Sonetto III has a frequency range of 42-25k Hz. With a minimum frequency of 32Hz, the RP-8000F II can go significantly deeper on the low side and provide stronger bass compared to the Sonetto III'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.

High Frequency
Floor-standing 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
RP-8000F II is a 8 ohms speaker compared to the Sonetto III which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the Sonetto III can provide this impedance level.
These two speakers also have different sensitivity levels. RP-8000F II sensitivity is rated at 98 dB and the Sonetto III's is rated at 89 dB. This 9 dB difference makes the Klipsch RP-8000F II a more sensitive speaker compared to Sonus Sonetto III, 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.
RP-8000F II can handle a max power of 250 watts RMS from the amp the whereas RP-8000F II has a max power handling value of 150 watts RMS , 100 watts less than the Sonetto III.
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 RP-8000F II and Sonetto III features dual binding post speaker terminals for bi-amping or bi-wiring.
Klipsch RP-8000F II's Binding post terminals allows Bi-amping or bi-wiring
Sonus Sonetto III's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
RP-8000F II has a rear firing port whereas Sonetto III has a bottom firing ports. Sonus Sonetto III's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-8000F II with its rear-firing port.
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 Klipsch RP-8000F II's and Sonus Sonetto III's external dimensions. Klipsch RP-8000F II has external dimensions of 1097.0 x 277.0 x 447.0mm ( 43-3/16 x 10-7/8 x 17-9/16inch) whereas Sonus Sonetto III has external dimensions of 1018.0 x 219.0 x 305.0mm ( 40 x 9 x 12inch) .
Klipsch RP-8000F II is clearly the larger of the two speakers. Its body is 58mm wider, 79mm taller and 142mm deeper than Sonus Sonetto III.
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 Klipsch RP-8000F II is approximately 1238.2cm2 / 191.9inch2 and base area of the Sonus Sonetto III is approximately 668.0cm2 / 103.5inch2. The RP-8000F II requires 85% more surface area than the Sonetto III which gives it a small disadvantage on placement in tight spaces.
