Drivers

One of the fundamental differences between these two speakers is that C 97 II is a 3-way design whereas the R-820F 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.

Driver Jamo C 97 II Klipsch R-820F
Driver Setup 3-way 2-way
Tweeter 1-inch 1-inch
Midrange 1 x 6-inch -
Woofer 3 x 6-inch 2 x 8-inch

C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer . On the other hand, the R-820F features a 1" Tweeter and 2 x 8" Copper-spun IMG Woofer .

Frequency Response

C 97 II has a frequency range of 32-24k Hz whereas R-820F has a frequency range of 35-21k Hz. With a minimum frequency of 32Hz, the C 97 II can go slightly deeper then the R-820F's min frequency of 35Hz.

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.

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.

C 97 II can handle a max power of 180 watts RMS from the amp the whereas R-820F has a max power handling value of 150 watts RMS, 30 watts less than the C 97 II.

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

C 97 II features Posts posts which make bi-amping or bi-wiring possible. R-820F has a Post which doesn't feature bi-amping/bi-wiring.
