In this review, we will be comparing RP-6203F and Concord, two Passive Floor-standing speakers from Klipsch and KLH.
Let's have a brief look at the main features
of Klipsch RP-6203F and KLH Concord first before getting into our more

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
Both RP-6203F and Concord are 2-way speakers.

RP-6203F features a 1" titanium Tractrix Horn Tweeter and 2 x 6.5" Cerametallic Woofer with a Crossover frequency at 1770 Hz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
RP-6203F has a frequency range of 38-25k 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 RP-6203F's min frequency of 38Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
RP-6203F and Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-6203F sensitivity is rated at 96 dB and the Concord's is at 94 dB. This 2 dB difference makes the Klipsch RP-6203F a more sensitive speaker compared to KLH Concord, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Concord can handle a max power of 225 watts RMS, whereas RP-6203F has a max power handling value of 125 watts RMS, 100 watts less than the Concord.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
RP-6203F features Binding 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
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch RP-6203F's and KLH Concord's external dimensions. Klipsch RP-6203F has external dimensions of 1006.0 x 236.0 x 446.0mm (39-5/8 x 9-5/16 x 17-9/16inch) 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).
KLH Concord is 24mm narrower and 66mm less deeper than Klipsch RP-6203F but it is also 20mm taller.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Klipsch RP-6203F needs about 31% more floor or shelf area. Klipsch RP-6203F is 66mm deeper, so it stands that much further out from the wall. KLH Concord is 20mm taller.
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 Klipsch RP-6203F is approximately 1052.6cm2 / 163.2inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The RP-6203F requires 31% more surface area than the Concord which gives it a small disadvantage on placement in tight spaces.
