What size room are the PSB Synchrony T600 and B&W 702 S2 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

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 702 S2 features a 1" Tweeter, a 6" Midrange and 3 x 6.5" Aerofoil Woofer.
Frequency Response
Synchrony T600 has a frequency range of 24-23k Hz whereas 702 S2 has a frequency range of 46-28k 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 702 S2's min frequency of 46Hz.
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 702 S2 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 702 S2's is rated at 90 dB. This 1 dB difference makes the B&W 702 S2 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 702 S2 30-300 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
Both Synchrony T600 and 702 S2 features dual binding post speaker terminals for bi-amping or bi-wiring.
PSB Synchrony T600's Binding post terminals allows Bi-amping or bi-wiring
B&W 702 S2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Synchrony T600 and 702 S2 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 B&W 702 S2'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 B&W 702 S2 has external dimensions of 1087 x 200 x 364 mm (42.8 x 7-7/8 x 14.3 inch).
PSB Synchrony T600 is 39mm shorter and 21mm less deeper than B&W 702 S2 but it is also 28mm wider.
Below you can see the front view size comparison of PSB Synchrony T600 and B&W 702 S2 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 B&W 702 S2 is approximately 728.0cm2 / 112.8inch2. The Synchrony T600 requires 7% more surface area than the 702 S2 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 PSB Synchrony T600 weighs 34.90kg / 76.8lbs and the B&W 702 S2 weighs 29.50kg / 64.9lbs. This makes the Synchrony T600 18% heavier than the 702 S2.
Here is a comparison of how Synchrony T600 and 702 S2's weights compare with the average, max and min weights in Passive Floor-standing class.

A generation apart: PSB Synchrony T600 is the newer design, against a 2017 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | PSB Synchrony T600 digs deeper - 24Hz against 46Hz. |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 90dB) - both want much the same power. |
| Amplifier match | B | B&W 702 S2 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 | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | PSB Synchrony T600: bi-amping; B&W 702 S2: bi-amping. B&W 702 S2 sits in a wider range (8 models), so a matched surround system is easier later. |
| Price | B | B&W 702 S2 is cheaper - $6,000 against $8,000, about 25% less. |
A PSB Synchrony T600 B B&W 702 S2
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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 46Hz anyway, which makes the cheaper B&W 702 S2 much easier to justify. If your amplifier is modest, vintage or valve-based, B&W 702 S2 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.
