Drivers
One of the fundamental differences between these two speakers is that Concord is a 2-way design whereas the SE 8000F is a 3-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.

Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer. On the other hand, the SE 8000F features a 1" Tweeter, a 6.5" Midrange and 3 x 8" Mineral-filled polypropylene Woofer.
Frequency Response
Concord has a frequency range of 28-23k Hz whereas SE 8000F has a frequency range of 45-21k Hz. With a minimum frequency of 28Hz, the Concord can go significantly deeper on the low side and provide stronger bass compared to the SE 8000F's min frequency of 45Hz.
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
Concord and SE 8000F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Concord sensitivity is rated at 94 dB and the SE 8000F's is at 95 dB. This 1 dB difference makes the Paradigm SE 8000F a more sensitive speaker compared to KLH Concord, 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 SE 8000F has a max power handling value of 150 watts RMS, 75 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
Concord features Post type posts and SE 8000F has a 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 KLH Concord's and Paradigm SE 8000F's external dimensions. 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) whereas Paradigm SE 8000F has external dimensions of 1169.0 x 299.0 x 451.0mm (46 x 11-3/4 x 17-3/4inch).
Paradigm SE 8000F is clearly the larger of the two speakers. Its body is 87mm wider, 143mm taller and 71mm deeper than KLH Concord.
Below you can see the front view size comparison of KLH Concord and Paradigm SE 8000F 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 KLH Concord is approximately 805.6cm2 / 124.9inch2 and base area of the Paradigm SE 8000F is approximately 1348.5cm2 / 209.0inch2. The Concord requires 40% less surface area than the SE 8000F 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 KLH Concord weighs 20.45kg / 45lbs and the Paradigm SE 8000F weighs 31.36kg / 69lbs. This makes the SE 8000F 53% heavier than the Concord.

These sit in different price classes - Paradigm SE 8000F costs roughly 1.7x 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 | A | KLH Concord digs deeper - 28Hz against 45Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (94dB vs 95dB) - both want much the same power. |
| Headroom | A | KLH Concord takes more power (225W vs 150W) - more in hand in a big room. |
| Size | depends | KLH Concord is easier to place; Paradigm SE 8000F is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | KLH Concord is cheaper - $1,000 against $1,700, about 41% less; arguably a different class. |
A KLH Concord B Paradigm SE 8000F
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 Paradigm SE 8000F 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 45Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Paradigm SE 8000F has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KLH Concord 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.
