In this review, we will be comparing Studio 680 and C 97 II, two Passive Floor-standing speakers from JBL and Jamo. Let's have a brief look at the main features
of JBL Studio 680 and Jamo C 97 II first before getting into our more
detailed comparison.
What size room are the JBL Studio 680 and Jamo C 97 II speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the JBL Studio 680 and Jamo C 97 II compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Studio 680 is a 2-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.

Studio 680 features a 1" compression driver with HDI (High Definition Imaging) waveguide Tweeter and 2 x 6.5" PolyPlas Woofer . On the other hand, the C 97 II features a 1" Tweeter , a 6" Midrange and 3 x 6" Composite Woofer .
Frequency Response
Studio 680 has a frequency range of 38-40k 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 Studio 680's min frequency of 38Hz.
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.

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
Studio 680 and C 97 II have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Studio 680 sensitivity is rated at 88 dB and the C 97 II's is at 89 dB. This 1 dB difference makes the Jamo C 97 II a more sensitive speaker compared to JBL Studio 680, 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.
Studio 680 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 Studio 680.
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 Studio 680 and C 97 II features dual binding post speaker terminals for bi-amping or bi-wiring.
JBL Studio 680's Binding post terminals allows Bi-amping or bi-wiring
Jamo C 97 II's Posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Studio 680 and C 97 II have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 JBL Studio 680's and Jamo C 97 II's external dimensions. JBL Studio 680 has external dimensions of 1036.0 x 228.0 x 307.0mm ( 40-3/4-inch x 8-15/16-inch x 12-1/16-inch) 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 clearly the larger of the two speakers. Its body is 20mm wider, 34mm taller and 95mm deeper than JBL Studio 680.
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 JBL Studio 680 is approximately 700.0cm2 / 108.5inch2 and base area of the Jamo C 97 II is approximately 997.0cm2 / 154.5inch2. The Studio 680 requires 30% less surface area than the C 97 II which gives it a small advantage 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 JBL Studio 680 weighs 22.68kg / 49.9lbs and the Jamo C 97 II weighs 24.55kg / 54lbs. This makes the C 97 II 8% heavier than the Studio 680.
Here is a comparison of how Studio 680 and C 97 II's weights compare with the average, max and min weights in Passive Floor-standing class.
