Drivers

One of the fundamental differences between these two speakers is that Wharfedale Diamond 12.4i is a -way design whereas the C 97 II 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.

Driver Setup -way 3-way
Tweeter 1-inch 1-inch
Midrange - 1 x 6-inch
Woofer 2 x 6.5-inch 3 x 6-inch

Wharfedale Diamond 12.4i features a 1" Soft-Dome Tweeter and 2 x 6.5" Mica-infused polypropylene Woofer . On the other hand, the C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer .

Frequency Response

Wharfedale Diamond 12.4i has a frequency range of 40-20k Hz whereas C 97 II has a frequency range of 32-24k Hz. With a minimum frequency of 32Hz, the C 97 II can go significantly deeper on the low side and provide stronger bass compared to the Wharfedale Diamond 12.4i's min frequency of 40Hz.

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.

Wharfedale Diamond 12.4i can handle a max power of 200 watts RMS from the amp the whereas C 97 II has a max power handling value of 180 watts RMS, 20 watts less than the Wharfedale Diamond 12.4i.

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 Wharfedale Diamond 12.4i and C 97 II features dual binding post speaker terminals for bi-amping or 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 Wharfedale Diamond 12.4i's and Jamo C 97 II's external dimensions. Wharfedale Diamond 12.4i has external dimensions of 1156.0 x 267.0 x 380.0mm ( 45-1/2inch x 10-1/2inch x 14-15/16inch ) whereas Jamo C 97 II has external dimensions of 1070.0 x 248.0 x 402.0mm ( 42-1/8 x 9-3/4 x 15-13/16inch) .

Jamo C 97 II is 19mm narrower and 86mm shorter than Wharfedale Diamond 12.4i but it is also 22mm deeper.

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 Wharfedale Diamond 12.4i is approximately 1014.6cm2 / 157.3inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The Wharfedale Diamond 12.4i requires 2% more surface area than the C 97 II 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 Wharfedale Diamond 12.4i weighs 22.27kg / 49lbs and the Jamo C 97 II weighs 24.55kg / 54lbs. This makes the C 97 II 10% heavier than the Wharfedale Diamond 12.4i.

Here is a comparison of how Wharfedale Diamond 12.4i and C 97 II's weights compare with the average, max and min weights in Passive Floor-standing class.
