Cello 40th features a 1" Magnesium dome Horn-Loaded Tweeter, a 6.5" Midrange and 2 x 6.5" Fibreglass sandwich Woofer with a Crossover frequency at 300Hz and 2600Hz. 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
Cello 40th has a frequency range of 35-30k 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 Cello 40th'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
Cello 40th 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. Cello 40th sensitivity is rated at 90 dB and the Synchrony T600's is rated at 89 dB. This 1 dB difference makes the Triangle Magellan Cello 40th 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.
Synchrony T600 can handle a max power of 300 watts RMS, whereas Cello 40th has a max power handling value of 200 watts RMS, 100 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.
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.
Triangle Magellan Cello 40th
Input Type and Bi-Amping / Bi-Wiring
Synchrony T600 features Binding post posts which make bi-amping or bi-wiring possible. Cello 40th 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
Cabinet Type and Port Position
Cello 40th has a front firing port whereas Synchrony T600 has a rear firing ports. Triangle Magellan Cello 40th's front-firing port gives more flexibility in placement in regards to proximity to walls compared to PSB Synchrony T600 with its rear-firing port.
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 Triangle Magellan Cello 40th's and PSB Synchrony T600's external dimensions. Triangle Magellan Cello 40th has external dimensions of 1080.0 x 250.0 x 340.0mm (42-1/2 x 9-13/16 x 13-3/8inch) 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 22mm narrower and 32mm shorter than Triangle Magellan Cello 40th but it is also 3mm deeper.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Triangle Magellan Cello 40th needs about 9% more floor or shelf area. Triangle Magellan Cello 40th is 32mm taller.
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 Triangle Magellan Cello 40th is approximately 850.0cm2 / 131.8inch2 and base area of the PSB Synchrony T600 is approximately 782.0cm2 / 121.2inch2. The Cello 40th requires 9% 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 Triangle Magellan Cello 40th weighs 38.80kg / 85.4lbs and the PSB Synchrony T600 weighs 34.90kg / 76.8lbs. This makes the Cello 40th 11% heavier than the Synchrony T600.
Here is a comparison of how Cello 40th and Synchrony T600's weights compare with the average, max and min weights in Passive Floor-standing class.

These sit in different price classes - Triangle Magellan Cello 40th costs roughly 2x 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 (90dB vs 89dB) - both want much the same power. |
| Amplifier match | A | Triangle Magellan Cello 40th is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | B | PSB Synchrony T600 takes more power (300W vs 200W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | B | PSB Synchrony T600: bi-amping. |
| Price | B | PSB Synchrony T600 is cheaper - $8,000 against $16,250, about 51% less; arguably a different class. |
A Triangle Magellan Cello 40th B PSB Synchrony T600
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?
PSB Synchrony T600 is the easier recommendation: it leads on most of the measured areas and costs less. Take Triangle Magellan Cello 40th if its size, looks or fit in your room suit you better. 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. If your amplifier is modest, vintage or valve-based, Triangle Magellan Cello 40th 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.
