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 B600 is a 6 ohms speaker compared to the TSi100 which has a nominal impedance of 8 ohms.

These two speakers also have different sensitivity levels. Synchrony B600 sensitivity is rated at 88 dB and the TSi100's is rated at 89 dB. This 1 dB difference makes the Polk TSi100 a more sensitive speaker compared to PSB Synchrony B600, 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 B600 can handle a max power of 150 watts RMS from the amp the whereas TSi100 has a max power handling value of 100 watts RMS, 50 watts less than the Synchrony B600.

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

Synchrony B600 features Binding post posts which make bi-amping or bi-wiring possible. TSi100 has a Pair of 5-way Binding Posts - Gold-Plated which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both Synchrony B600 and TSi100 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

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 B600's and Polk TSi100's external dimensions. PSB Synchrony B600 has external dimensions of 402.0 x 232.0 x 345.0mm ( 15-13/16 x 9-1/8 x 13-9/16inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .

PSB Synchrony B600 is clearly the larger of the two speakers. Its body is 54.2mm wider, 122.6mm taller and 86mm deeper than Polk TSi100.

Below you can see the front view size comparison of PSB Synchrony B600 and Polk TSi100 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 B600 is approximately 800.4cm2 / 124.1inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The Synchrony B600 requires 74% more surface area than the TSi100 which gives it a small disadvantage on placement in tight spaces.

Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 B600 weighs 10.45kg / 23lbs and the Polk TSi100 weighs 4.53kg / 10lbs. This makes the Synchrony B600 131% heavier than the TSi100.
