In this review, we will be comparing Studio 690 and Concord, two Passive Floor-standing speakers from JBL and KLH. Let's have a brief look at the main features
of JBL Studio 690 and KLH Concord first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the JBL Studio 690 and KLH Concord compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Studio 690 features a 1" compression driver with HDI (High Definition Imaging) waveguide Tweeter and 2 x 8" PolyPlas Woofer . On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Studio 690 has a frequency range of 36-40k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the Studio 690's min frequency of 36Hz.
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 690 is a 6 ohms speaker compared to the Concord which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Studio 690 sensitivity is rated at 90 dB and the Concord's is rated at 94 dB. This 4 dB difference makes the KLH Concord a more sensitive speaker compared to JBL Studio 690, 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 690 can handle a max power of 250 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 250 watts less than the Studio 690.
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 690 features 5-Way post posts which make bi-amping or bi-wiring possible. Concord has a 5-Way post which doesn't feature bi-amping/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 JBL Studio 690's and KLH Concord's external dimensions. JBL Studio 690 has external dimensions of 1096.0 x 299.0 x 383.0mm ( 43-1/8-inch x 11-3/4-inch x 15-1/16-inch) whereas KLH Concord has external dimensions of 1026.0 x 212.0 x 380.0mm ( 40-3/8 x 8-5/16 x 14-15/16inch) .
JBL Studio 690 is clearly the larger of the two speakers. Its body is 87mm wider, 70mm taller and 3mm deeper than KLH Concord.
Below you can see the front view size comparison of JBL Studio 690 and KLH Concord in scale.

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 690 is approximately 1145.2cm2 / 177.5inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Studio 690 requires 42% more surface area than the Concord 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 JBL Studio 690 weighs 29.45kg / 64.8lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Studio 690 44% heavier than the Concord.
Here is a comparison of how Studio 690 and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
