With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the Novus N5T 5.25" Floorstanding Tower's min frequency of 36Hz.
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
Novus N5T 5.25" Floorstanding Tower
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
Novus N5T 5.25" Floorstanding Tower 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 Novus N5T 5.25" Floorstanding Tower can provide this impedance level.
These two speakers also have different sensitivity levels. Novus N5T 5.25" Floorstanding Tower sensitivity is rated at 88 dB and the Concord's is rated at 94 dB. This 6 dB difference makes the KLH Concord a more sensitive speaker compared to Aperion Novus N5T 5.25" Floorstanding Tower, hence will play louder with the same amount of watts.
Sensitivity

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.
Novus N5T 5.25" Floorstanding Tower can handle a max power of 300 watts RMS, whereas Concord has a max power handling value of watts RMS, 300 watts less than the Novus N5T 5.25" Floorstanding Tower.
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.

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 Aperion Novus N5T 5.25" Floorstanding Tower's and KLH Concord's external dimensions. Aperion Novus N5T 5.25" Floorstanding Tower has external dimensions of 939.8 x 177.8 x 221.0mm (37 x 7 x 8.7inch) 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 clearly the larger of the two speakers. Its body is 34.2mm wider, 86.2mm taller and 159mm deeper than Aperion Novus N5T 5.25" Floorstanding Tower.
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 Aperion Novus N5T 5.25" Floorstanding Tower is approximately 392.9cm2 / 60.9inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The Novus N5T 5.25" Floorstanding Tower requires 51% less surface area than the Concord 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 Aperion Novus N5T 5.25" Floorstanding Tower weighs 12.25kg / 27lbs and the KLH Concord weighs 20.45kg / 45lbs. This makes the Concord 67% heavier than the Novus N5T 5.25" Floorstanding Tower.
Here is a comparison of how Novus N5T 5.25" Floorstanding Tower and Concord's weights compare with the average, max and min weights in Passive Floor-standing class.

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.
| Area | Better | Why |
|---|
| Bass |
B |
KLH Concord digs deeper - 28Hz against 36Hz. 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. |
| Amplifier match |
B |
KLH Concord is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Size |
depends |
Aperion Novus N5T 5.25" Floorstanding Tower is easier to place; KLH Concord is bigger, which usually goes with fuller bass. Your room decides. |
| Price |
evenly matched |
Much the same money ($1,049 vs $1,000 a pair). |
A Aperion Novus N5T 5.25" Floorstanding Tower
B KLH Concord
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 a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 36Hz anyway, so judge these on the other rows instead. In a large or open-plan room, KLH Concord has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Aperion Novus N5T 5.25" Floorstanding Tower is the easier speaker to get right.
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.
