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

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that LRS+ is a -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.

LRS+ features a " Tweeter and x " Woofer. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
LRS+ has a frequency range of 50-20k 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 LRS+'s min frequency of 50Hz.
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
LRS+ is a 4 ohms speaker compared to the Concord which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the LRS+ can provide this impedance level.
These two speakers also have different sensitivity levels. LRS+ sensitivity is rated at 86 dB and the Concord's is rated at 94 dB. This 8 dB difference makes the KLH Concord a more sensitive speaker compared to Magnepan LRS+, hence will play louder with the same amount of watts.

Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
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 Magnepan LRS+'s and KLH Concord's external dimensions. Magnepan LRS+ has external dimensions of 1219.2 x 330.2 x 25.4mm (48 x 13 x 1inch) 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 118.2mm narrower and 193.2mm shorter than Magnepan LRS+ but it is also 354.6mm deeper.
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.
KLH Concord needs about 861% more floor or shelf area. KLH Concord is 355mm deeper, so it stands that much further out from the wall. Magnepan LRS+ is 193mm 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 Magnepan LRS+ is approximately 83.9cm2 / 13.0inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The LRS+ requires 90% less surface area than the Concord which gives it a small advantage on placement in tight spaces.
