Midrange 1 x 5.25-inch 1 x 5.25-inch
Woofer 3 x 6.5-inch 2 x 7-inch

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 L600 features a 1" Pinnacle Ring Radiator Tweeter , a 5.25" Midrange and 2 x 7" Polypropylene Woofer with a Crossover frequency at 410Hz and 2900Hz.

Frequency Response

Synchrony T600 has a frequency range of 24-23k Hz whereas L600 has a frequency range of 34-38k 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 L600's min frequency of 34Hz.

Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Impedance and Sensitivity

Synchrony T600 and L600 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. Synchrony T600 sensitivity is rated at 89 dB and the L600's is at 86 dB. This 3 dB difference makes the PSB Synchrony T600 a more sensitive speaker compared to Polk L600, 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 Synchrony T600 and the Synchrony T600 can provide this impedance level.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.

Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impedance, sensitivity and system efficiencies.

Input Type and Bi-Amping / Bi-Wiring

Both Synchrony T600 and L600 features dual binding post speaker terminals for bi-amping or bi-wiring.

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 Polk L600 is approximately 1410.1cm2 / 218.6inch2. The Synchrony T600 requires 45% less surface area than the L600 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 PSB Synchrony T600 weighs 34.90kg / 76.8lbs and the Polk L600 weighs 35.30kg / 77.7lbs. This makes the L600 1% heavier than the Synchrony T600.

Here is a comparison of how Synchrony T600 and L600's weights compare with the average, max and min weights in Passive Floor-standing class.
