Gold 300 6G features a 1" MPD III Tweeter, a 3" Midrange and 2 x 6" HDT C-CAM Woofer with a Crossover frequency at 800 Hz - 2700 Hz. 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
Gold 300 6G has a frequency range of 45 Hz – 60 kHz 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 Gold 300 6G'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
Gold 300 6G and Synchrony T600 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Gold 300 6G sensitivity is rated at 87 dB and the Synchrony T600's is at 89 dB. This 2 dB difference makes the PSB Synchrony T600 a more sensitive speaker compared to Monitor Audio Gold 300 6G, 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 Gold 300 6G and the Gold 300 6G 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.
Synchrony T600 can handle a max power of 300 watts RMS, whereas Gold 300 6G has a max power handling value of 250 watts RMS, 50 watts less than the Synchrony T600.
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.

considering, and watch both numbers move.

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 Monitor Audio Gold 300 6G's and PSB Synchrony T600's external dimensions. Monitor Audio Gold 300 6G has external dimensions of 340.0 x 1099.0 x 464.0mm (13-3/8 x 43-1/4 x 18-1/4) 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).
Monitor Audio Gold 300 6G is clearly the larger of the two speakers. Its body is 112mm wider, 51mm taller and 121mm deeper than PSB Synchrony T600.
Below you can see the front view size comparison of Monitor Audio Gold 300 6G and PSB Synchrony T600 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 Monitor Audio Gold 300 6G is approximately 5099.4cm2 / 790.4inch2 and base area of the PSB Synchrony T600 is approximately 782.0cm2 / 121.2inch2. The Gold 300 6G requires 552% 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 Monitor Audio Gold 300 6G weighs 21.25kg / 46.8lbs and the PSB Synchrony T600 weighs 34.90kg / 76.8lbs. This makes the Synchrony T600 64% heavier than the Gold 300 6G.
Here is a comparison of how Gold 300 6G and Synchrony T600's weights compare with the average, max and min weights in Passive Floor-standing class.

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.

A Monitor Audio Gold 300 6G
B PSB Synchrony T600
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?
The usual trade-off: PSB Synchrony T600 measures better, Monitor Audio Gold 300 6G costs about 30% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 45Hz anyway, which makes the cheaper Monitor Audio Gold 300 6G much easier to justify. In a large or open-plan room, Monitor Audio Gold 300 6G 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.
