Drivers
One of the fundamental differences between these two speakers is that Silver 300 7G 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.

Silver 300 7G features a 1" gold dome C-CAM with Uniform Dispersion (UD) Waveguide II Tweeter, a 3" Midrange and 2 x 6" C-CAM RST II Woofer. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
Silver 300 7G has a frequency range of 31-35k 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 Silver 300 7G's min frequency of 31Hz.
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
Silver 300 7G and Concord have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Silver 300 7G sensitivity is rated at 87.5 dB and the Concord's is at 94 dB. This 6 dB difference makes the KLH Concord a more sensitive speaker compared to Monitor Audio Silver 300 7G, 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.
Silver 300 7G can handle a max power of 200 watts RMS, whereas Concord has a max power handling value of watts RMS, 200 watts less than the Silver 300 7G.
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.

Input Type and Bi-Amping / Bi-Wiring
Silver 300 7G 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 Monitor Audio Silver 300 7G's and KLH Concord's external dimensions. Monitor Audio Silver 300 7G has external dimensions of 1036.0 x 277.0 x 388.0mm (40-3/4 x 10-7/8 x 15-1/4inch) 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).
Monitor Audio Silver 300 7G is clearly the larger of the two speakers. Its body is 65mm wider, 10mm taller and 8mm deeper than KLH Concord.
Below you can see the front view size comparison of Monitor Audio Silver 300 7G and KLH Concord in scale.

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 Monitor Audio Silver 300 7G is approximately 1074.8cm2 / 166.6inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Silver 300 7G requires 33% 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 Monitor Audio Silver 300 7G weighs 19.32kg / 42.5lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Concord 6% heavier than the Silver 300 7G.
Here is a comparison of how Silver 300 7G and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Monitor Audio Silver 300 7G costs roughly 2.6x 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 31Hz. A subwoofer would even that out. |
| Amplifier needs |
B |
KLH Concord is more sensitive (94dB vs 88dB), so it goes louder on the same amplifier. |
| Size |
depends |
KLH Concord is easier to place; Monitor Audio Silver 300 7G is bigger, which usually goes with fuller bass. Your room decides. |

depends neither is better in the abstract - it turns on your room, placement 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 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. 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. Think about the whole system, not just the speakers: the roughly $1,600 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
