In this review, we will be comparing Synchrony T600 and La Scala AL5, two Passive Floor-standing speakers from PSB and Klipsch. Let's have a brief look at the main features
of PSB Synchrony T600 and Klipsch La Scala AL5 first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the PSB Synchrony T600 and Klipsch La Scala AL5 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 La Scala AL5 features a 1" polyimide diaphragm compression horn-loaded Tweeter , a 2" Midrange and 1 x 15" fiber-composite cone with folded horn Woofer .
Frequency Response
Synchrony T600 has a frequency range of 24-23k Hz whereas La Scala AL5 has a frequency range of 51-20k 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 La Scala AL5's min frequency of 51Hz.
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 is a 4 ohms speaker compared to the La Scala AL5 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 La Scala AL5's is rated at 105 dB. This 16 dB difference makes the Klipsch La Scala AL5 a more sensitive speaker compared to PSB Synchrony T600, hence will play louder with the same amount of watts.

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.
Synchrony T600 can handle a max power of 300 watts RMS from the amp the whereas La Scala AL5 has a max power handling value of 100 watts RMS, 200 watts less than the Synchrony T600.
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 La Scala AL5 features dual binding post speaker terminals for bi-amping or bi-wiring.

Physical Specs
Size of a speaker can sometimes become 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 Klipsch La Scala AL5'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 Klipsch La Scala AL5 has external dimensions of 1016.0 x 616.0 x 643.0mm ( 40 x 24-1/4 x 25-5/16inch) .
PSB Synchrony T600 is 388mm narrower and 300mm less deeper than Klipsch La Scala AL5 but it is also 32mm taller.
Below you can see the front view size comparison of PSB Synchrony T600 and Klipsch La Scala AL5 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 Klipsch La Scala AL5 is approximately 3960.9cm2 / 613.9inch2. The Synchrony T600 requires 80% less surface area than the La Scala AL5 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 Klipsch La Scala AL5 weighs 91.36kg / 201lbs. This makes the La Scala AL5 162% heavier than the Synchrony T600.
Here is a comparison of how Synchrony T600 and La Scala AL5's weights compare with the average, max and min weights in Passive Floor-standing class.
