In this review, we will be comparing Ultra Evolution Tower and Concord, two Passive Floor-standing speakers from SVS and KLH. Let's have a brief look at the main features
of SVS Ultra Evolution Tower 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 SVS Ultra Evolution Tower and KLH Concord 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 Ultra Evolution Tower is a 3-way design whereas the Concord 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.

Ultra Evolution Tower features a 1" aluminum Dome Tweeter , a 4.5" Midrange and 4 x 5.25" Composite glass-fiber Woofer with a Crossover frequency at 170HZ and 1800Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer .
Frequency Response
Ultra Evolution Tower has a frequency range of 30-40k Hz whereas Concord has a frequency range of 28-23k Hz. With a minimum frequency of 28Hz, the Concord can go slightly deeper then the Ultra Evolution Tower's min frequency of 30Hz.
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
Ultra Evolution Tower 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. Ultra Evolution Tower sensitivity is rated at 87 dB and the Concord's is rated at 94 dB. This 7 dB difference makes the KLH Concord a more sensitive speaker compared to SVS Ultra Evolution 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.
Ultra Evolution Tower can handle a max power of 300 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS, 300 watts less than the Ultra Evolution 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
Ultra Evolution Tower features Gold-plated 5-way 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 SVS Ultra Evolution Tower's and KLH Concord's external dimensions. SVS Ultra Evolution Tower has external dimensions of 1130 x 218 x 424mm ( 44.49 x 8.58 x 16.69”) 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) .
SVS Ultra Evolution Tower is clearly the larger of the two speakers. Its body is 6mm wider, 104mm taller and 44mm deeper than KLH Concord.
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 SVS Ultra Evolution Tower is approximately 924.3cm2 / 143.3inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Ultra Evolution Tower requires 15% 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 SVS Ultra Evolution Tower weighs 27.00kg / 59.4lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Ultra Evolution Tower 32% heavier than the Concord.
Here is a comparison of how Ultra Evolution Tower and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.
