Drivers

One of the fundamental differences between these two speakers is that Concord is a 2-way design whereas the Forte IV 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 KLH Concord Klipsch Forte IV
Driver Setup 2-way 3-way
Tweeter 1-inch 1-inch
Midrange - 1 x 1.75-inch
Woofer 2 x 6.5-inch 1 x 12-inch

Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer . On the other hand, the Forte IV features a 1" titanium-diaphragm compression horn-loaded Tweeter , a 1.75" Midrange and 1 x 12" Fibercomposite Woofer .

Frequency Response

Concord has a frequency range of 28-23k Hz whereas Forte IV has a frequency range of 38-20k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the Forte IV'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

Concord and Forte IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Concord sensitivity is rated at 94 dB and the Forte IV's is at 99 dB. This 5 dB difference makes the Klipsch Forte IV a more sensitive speaker compared to KLH Concord, 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.

Concord can handle a max power of 100 watts RMS from the amp the whereas Concord has a max power handling value of watts RMS , 100 watts less than the Forte IV.

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

Forte IV features Post posts which make bi-amping or bi-wiring possible. Concord has a 5-Way post which doesn't feature bi-amping/bi-wiring.

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) whereas Klipsch Forte IV has external dimensions of 909.0 x 423.0 x 331.0mm ( 35-3/4 x 16-5/8 x 13inch) .

Klipsch Forte IV is 117mm shorter and 49mm less deeper than KLH Concord but it is also 211mm wider.

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 KLH Concord is approximately 805.6cm2 / 124.9inch2 and base area of the Klipsch Forte IV is approximately 1400.1cm2 / 217.0inch2. The Concord requires 42% less surface area than the Forte IV 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 KLH Concord weighs 20.45kg / 45lbs and the Klipsch Forte IV weighs 32.73kg / 72lbs. This makes the Forte IV 60% heavier than the Concord.
