Blade One Meta features a 1" aluminium dome with MAT Tweeter, a 5" Midrange and 4 x 9" aluminium cone Woofer with a Crossover frequency at 350Hz and 2000Hz. On the other hand, the 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.
Frequency Response
Blade One Meta has a frequency range of 35-35k Hz whereas Synchrony T600 has a frequency range of 24-23k 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 Blade One Meta's min frequency of 35Hz.
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
Blade One Meta and Synchrony T600 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Blade One Meta sensitivity is rated at 88 dB and the Synchrony T600's is at 89 dB. This 1 dB difference makes the PSB Synchrony T600 a more sensitive speaker compared to KEF Blade One Meta, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Blade One Meta and the Blade One Meta can provide this impedance level.
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.
Blade One Meta can handle a max power of 400 watts RMS, whereas Synchrony T600 has a max power handling value of 300 watts RMS, 100 watts less than the Blade One Meta.
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. Blade One Meta has a Binding posts which doesn't feature bi-amping/bi-wiring.
PSB Synchrony T600's Binding post terminals allows Bi-amping or 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 KEF Blade One Meta's and PSB Synchrony T600's external dimensions. KEF Blade One Meta has external dimensions of 1590 x 363 x 540 mm (62.5 x 14.3 x 21.2 in.) whereas PSB Synchrony T600 has external dimensions of 1048.0 x 228.0 x 343.0mm (41-1/4 x 9 x 13-1/2inch).
KEF Blade One Meta is clearly the larger of the two speakers. Its body is 135mm wider, 542mm taller and 197mm deeper than PSB Synchrony T600.
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 KEF Blade One Meta is approximately 1960.2cm2 / 303.8inch2 and base area of the PSB Synchrony T600 is approximately 782.0cm2 / 121.2inch2. The Blade One Meta requires 151% more surface area than the Synchrony T600 which gives it a small disadvantage 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 KEF Blade One Meta weighs 57.20kg / 125.8lbs and the PSB Synchrony T600 weighs 34.90kg / 76.8lbs. This makes the Blade One Meta 64% heavier than the Synchrony T600.
Here is a comparison of how Blade One Meta and Synchrony T600's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - KEF Blade One Meta costs roughly 4.4x what PSB Synchrony T600 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 |
PSB Synchrony T600 digs deeper - 24Hz against 35Hz. |
| Amplifier needs |
evenly matched |
Similar sensitivity (88dB vs 89dB) - both want much the same power. |
| Headroom |
A |
KEF Blade One Meta takes more power (400W vs 300W) - more in hand in a big room. |
| Size |
depends |
PSB Synchrony T600 is easier to place; KEF Blade One Meta is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
B |
PSB Synchrony T600: bi-amping. |
| Price |
B |
PSB Synchrony T600 is cheaper - $8,000 against $35,000, about 77% less; arguably a different class. |

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?
PSB Synchrony T600 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 35Hz anyway, so judge these on the other rows instead. Match it to your room: we rate KEF Blade One Meta the better fit for a very large room; elsewhere the two are rated the same.
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.
