What size room are the Spendor A7 and PSB Synchrony T600 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

Drivers
One of the fundamental differences between these two speakers is that A7 is a 2-way design whereas the Synchrony T600 is a 3-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.

A7 features a 0.87" Tweeter and 1 x 7.09" Woofer with a Crossover frequency at 3,700 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
A7 has a frequency range of 32-25k 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 A7's min frequency of 32Hz.
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
A7 is a 8 ohms speaker compared to the Synchrony T600 which has a nominal impedance of 4 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. A7 sensitivity is rated at 88 dB and the Synchrony T600's is rated at 89 dB. This 1 dB difference makes the PSB Synchrony T600 a more sensitive speaker compared to Spendor A7, hence will play louder with the same amount of watts.

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. A7 has a Binding post 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 Spendor A7's and PSB Synchrony T600's external dimensions. Spendor A7 has external dimensions of 934.0 x 177.8 x 304.8mm (36.77 x 7 x 12inch) 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).
PSB Synchrony T600 is clearly the larger of the two speakers. Its body is 50.2mm wider, 114mm taller and 38.2mm deeper than Spendor A7.
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 Spendor A7 is approximately 541.9cm2 / 84.0inch2 and base area of the PSB Synchrony T600 is approximately 782.0cm2 / 121.2inch2. The A7 requires 31% less surface area than the Synchrony T600 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 Spendor A7 weighs 18.00kg / 39.6lbs and the PSB Synchrony T600 weighs 34.90kg / 76.8lbs. This makes the Synchrony T600 94% heavier than the A7.
Here is a comparison of how A7 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.
| Area | Better | Why |
|---|
| Bass |
B |
PSB Synchrony T600 digs deeper - 24Hz against 32Hz. A subwoofer would even that out. |
| Amplifier needs |
evenly matched |
Similar sensitivity (88dB vs 89dB) - both want much the same power. |
| Amplifier match |
A |
Spendor A7 is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Size |
depends |
Spendor A7 is easier to place; PSB Synchrony T600 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability |
B |
PSB Synchrony T600: bi-amping. |
| Price |
A |
Spendor A7 is cheaper - $6,300 against $8,000, about 21% less. |
A Spendor A7
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, Spendor A7 costs about 21% 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 32Hz anyway, which makes the cheaper Spendor A7 much easier to justify. Match it to your room: we rate Spendor A7 the better fit for a small room and a mid-size room, and PSB Synchrony T600 for a large room and a very large room.
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.
