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.

606 S2 AE can handle a max power of 150 watts RMS from the amp the whereas 606 S2 AE has a max power handling value of 120 watts RMS , 30 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

Both 606 S2 AE and Synchrony B600 features dual binding post speaker terminals for bi-amping or bi-wiring.

PSB Synchrony B600's Binding post terminals allows Bi-amping or bi-wiring

Cabinet Type and Port Position

Both 606 S2 AE and Synchrony B600 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 B&W 606 S2's and PSB Synchrony B600's external dimensions. B&W 606 S2 has external dimensions of 347.0 x 191.0 x 326.0mm ( 13-5/8 x 7-1/2 x 12-13/16inch) whereas 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) .

PSB Synchrony B600 is clearly the larger of the two speakers. Its body is 41mm wider, 55mm taller and 19mm deeper than B&W 606 S2.

Below you can see the front view size comparison of B&W 606 S2 and PSB Synchrony B600 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 B&W 606 S2 is approximately 622.7cm² / 96.5inch² and base area of the PSB Synchrony B600 is approximately 800.4cm² / 124.1inch². The 606 S2 AE requires 22% less surface area than the Synchrony B600 which gives it a small advantage 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 B&W 606 S2 weighs 6.90kg / 15.2lbs and the PSB Synchrony B600 weighs 10.45kg / 23lbs. This makes the Synchrony B600 51% heavier than the 606 S2 AE.
