In this review, we will be comparing A3t and Concord, two Passive Floor-standing speakers from Perlisten and KLH.
Let's have a brief look at the main features
of Perlisten A3t and KLH Concord first before getting into our more
detailed comparison.

Drivers
One of the fundamental differences between these two speakers is that A3t 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.

A3t features a " Tweeter and x " Woofer. On the other hand, the Concord features a 1" anodized aluminum Tweeter and 2 x 6.5" Kevlar Woofer.
Frequency Response
A3t has a frequency range of 31-27k 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 A3t'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
A3t 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 A3t can provide this impedance level.
These two speakers also have different sensitivity levels. A3t sensitivity is rated at 87.7 dB and the Concord's is rated at 94 dB. This 6 dB difference makes the KLH Concord a more sensitive speaker compared to Perlisten A3t, hence will play louder with the same amount of watts.

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.
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
A3t 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 Perlisten A3t's and KLH Concord's external dimensions. Perlisten A3t has external dimensions of 1285.0 x 279.9 x 389.9mm (50.59 x 11.02 x 15.35inch) 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).
Perlisten A3t is clearly the larger of the two speakers. Its body is 67.9mm wider, 259mm taller and 9.9mm deeper than KLH Concord.
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 Perlisten A3t is approximately 1091.3cm2 / 169.2inch2 and base area of the KLH Concord is approximately 805.6cm2 / 124.9inch2. The A3t requires 35% more surface area than the Concord which gives it a small disadvantage on placement in tight spaces.
What's in the Box of KLH Concord?
Here are the items that come with the Concord:
- Floorstanding loudspeaker
- Grille
- 4 Spike feet (w/ locking nut attached)
- 4 Protective discs
- 4 Rubber feet
- Port plug
