Drivers
One of the fundamental differences between these two speakers is that Studio 680 is a 2-way design whereas the Prime Tower 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 Prime Tower features a 1" aluminum dome Tweeter , a 4.5" Midrange and 2 x 6.5" Polypropylene Woofer with a Crossover frequency at 350Hz and 2100Hz.
Frequency Response
Studio 680 has a frequency range of 38-40k Hz whereas Prime Tower has a frequency range of 30-25k Hz. With a minimum frequency of 30Hz, the Prime Tower 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.

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
Studio 680 is a 6 ohms speaker compared to the Prime Tower which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Studio 680 sensitivity is rated at 88 dB and the Prime Tower's is rated at 87 dB. This 1 dB difference makes the JBL Studio 680 a more sensitive speaker compared to SVS Prime Tower, 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 250 watts RMS from the amp the whereas Studio 680 has a max power handling value of 200 watts RMS , 50 watts less than the Prime Tower.
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
Studio 680 features Binding post posts which make bi-amping or bi-wiring possible. Prime Tower has a 5-Way post which doesn't feature bi-amping/bi-wiring.
JBL Studio 680's Binding post terminals allows Bi-amping or bi-wiring
SVS Prime Tower's 5-Way post terminals
Cabinet Type and Port Position
Both Studio 680 and Prime Tower 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 SVS Prime Tower'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 SVS Prime Tower has external dimensions of 931.0 x 204.0 x 297.0mm ( 36-5/8 x 8 x 11-11/16inch) .
JBL Studio 680 is clearly the larger of the two speakers. Its body is 24mm wider, 105mm taller and 10mm deeper than SVS Prime Tower.
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 SVS Prime Tower is approximately 605.9cm2 / 93.9inch2. The Studio 680 requires 16% more surface area than the Prime Tower which gives it a small disadvantage on placement in tight spaces.
