Synchrony T600 features a 1" titanium with ferrofluid cooling and neodymium magnet Dome Tweeter, a 5.25" Midrange and 3 x 6.5" Carbon fiber Woofer with a Crossover frequency at 450Hz and 1800Hz. On the other hand, the Aria K2 936K2 features a 1" aluminum/magnesium with waveguide inverted dome Tweeter, a 6.5" Midrange and 3 x 6.5" K2 aramid fiber/fiberglass Woofer.
Frequency Response
Synchrony T600 has a frequency range of 24-23k Hz whereas Aria K2 936K2 has a frequency range of 39-28k Hz. With a minimum frequency of 24Hz, the Synchrony T600 can go significantly deeper on the low side and provide stronger bass compared to the Aria K2 936K2's min frequency of 39Hz.
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
Synchrony T600 is a 4 ohms speaker compared to the Aria K2 936K2 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 Synchrony T600 can provide this impedance level.
These two speakers also have different sensitivity levels. Synchrony T600 sensitivity is rated at 89 dB and the Aria K2 936K2's is rated at 92 dB. This 3 dB difference makes the Focal Aria K2 936K2 a more sensitive speaker compared to PSB Synchrony T600, 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.
Both handle the same maximum of 300 watts RMS, though Synchrony T600 is rated 20-300 watts and Aria K2 936K2 50-300 watts.
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
Synchrony T600 features Binding post posts which make bi-amping or bi-wiring possible. Aria K2 936K2 has a Binding 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 PSB Synchrony T600's and Focal Aria K2 936K2's external dimensions. PSB Synchrony T600 has external dimensions of 1048.0 x 228.0 x 343.0mm (41-1/4 x 9 x 13-1/2inch) whereas Focal Aria K2 936K2 has external dimensions of 1148.0 x 294.0 x 374.0mm (45-3/16 x 11-9/16 x 14-11/16inch).
Focal Aria K2 936K2 is clearly the larger of the two speakers. Its body is 66mm wider, 100mm taller and 31mm deeper than PSB Synchrony T600.
Below you can see the front view size comparison of PSB Synchrony T600 and Focal Aria K2 936K2 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 PSB Synchrony T600 is approximately 782.0cm2 / 121.2inch2 and base area of the Focal Aria K2 936K2 is approximately 1099.6cm2 / 170.4inch2. The Synchrony T600 requires 29% less surface area than the Aria K2 936K2 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 PSB Synchrony T600 weighs 34.90kg / 76.8lbs and the Focal Aria K2 936K2 weighs 29.09kg / 64lbs. This makes the Synchrony T600 20% heavier than the Aria K2 936K2.

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 | A | PSB Synchrony T600 digs deeper - 24Hz against 39Hz. |
| Amplifier needs | B | Focal Aria K2 936K2 is more sensitive (92dB vs 89dB), so it goes louder on the same amplifier. |
| Amplifier match | B | Focal Aria K2 936K2 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | evenly matched | Similar power handling (300W vs 300W). |
| Size | depends | PSB Synchrony T600 is easier to place; Focal Aria K2 936K2 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | PSB Synchrony T600: bi-amping. Focal Aria K2 936K2 sits in a wider range (7 models), so a matched surround system is easier later. |
| Price | B | Focal Aria K2 936K2 is cheaper - $6,598 against $8,000, about 18% less. |
A PSB Synchrony T600 B Focal Aria K2 936K2
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?
Focal Aria K2 936K2 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 39Hz anyway, which makes the cheaper Focal Aria K2 936K2 much easier to justify. In a large or open-plan room, Focal Aria K2 936K2 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, PSB Synchrony T600 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.
