Low Frequency
Floor-standing Speakers
Novus N6T 6.5" Floorstanding Tower Speaker
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 N6T 6.5" Floorstanding Tower Speaker 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 N6T 6.5" Floorstanding Tower Speaker can provide this impedance level.
These two speakers also have different sensitivity levels. Novus N6T 6.5" Floorstanding Tower Speaker sensitivity is rated at 90 dB and the Concord's is rated at 94 dB. This 4 dB difference makes the KLH Concord a more sensitive speaker compared to Aperion Novus N6T 6.5" Floorstanding Tower Speaker, 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 N6T 6.5" Floorstanding Tower Speaker can handle a max power of 400 watts RMS, whereas Concord has a max power handling value of watts RMS, 400 watts less than the Novus N6T 6.5" Floorstanding Tower Speaker.
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.

These sit in different price classes - Aperion Novus N6T 6.5" Floorstanding Tower Speaker costs roughly 3.8x 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 32Hz. A subwoofer would even that out. |
| Amplifier needs |
B |
KLH Concord is more sensitive (94dB vs 90dB), 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 N6T 6.5" Floorstanding Tower Speaker is easier to place; KLH Concord is bigger, which usually goes with fuller bass. Your room decides. |
| Price |
B |
KLH Concord is cheaper - $1,000 against $3,796, about 74% less; arguably a different class. |

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 is the easier recommendation: it leads on most of the measured areas and costs less. Take Aperion Novus N6T 6.5" Floorstanding Tower Speaker if its size, looks or fit in your room suit you better. 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 N6T 6.5" Floorstanding Tower Speaker is the easier speaker to get right. 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.
