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 Q7 Meta 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.

Q7 Meta features a 0.75" vented aluminum dome with MAT absorber Hard dome Tweeter, a 4" Midrange and 2 x 6.5" Aluminum Woofer with a Crossover frequency at 440 Hz, 2.3 kHz. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
Q7 Meta has a frequency range of 46-20k 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 Q7 Meta's min frequency of 46Hz.
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
Q7 Meta 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 Q7 Meta can provide this impedance level.
These two speakers also have different sensitivity levels. Q7 Meta 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 KEF Q7 Meta, 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 Q7 Meta has a max power handling value of 200 watts RMS, 25 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
Q7 Meta features 5-Way post type posts and Concord has a 5-Way post type posts. None of these speakers 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 KEF Q7 Meta's and KLH Concord's external dimensions. KEF Q7 Meta has external dimensions of 1001 x 317 x 315 mm (39.4 x 12.5 x 12.4 in.) 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).
KEF Q7 Meta is 25mm shorter and 65mm less deeper than KLH Concord but it is also 105mm 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 KEF Q7 Meta is approximately 998.6cm2 / 154.8inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Q7 Meta requires 24% 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 KEF Q7 Meta weighs 18.45kg / 40.6lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Concord 11% heavier than the Q7 Meta.
Here is a comparison of how Q7 Meta and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - KEF Q7 Meta costs roughly 1.8x what KLH Concord does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | B | KLH Concord digs deeper - 28Hz against 46Hz. |
| Amplifier needs | B | KLH Concord is more sensitive (94dB vs 87dB), so it goes louder on the same amplifier. |
| Amplifier match | B | KLH Concord is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (200W vs 225W). |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Price | B | KLH Concord is cheaper - $1,000 against $1,800, about 44% less; arguably a different class. |
A KEF Q7 Meta B KLH Concord
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KLH Concord is the easier recommendation: it leads on most of the measured areas and costs less. Take KEF Q7 Meta if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 46Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, KLH Concord is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
