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.

SS-CS8 can handle a max power of 200 watts RMS from the amp the whereas SS-CS8 has a max power handling value of 145 watts RMS , 55 watts less than the Monitor XT35.

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

SS-CS8 features 5-Way post type posts and Monitor XT35 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position

Both SS-CS8 and Monitor XT35 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 Sony SS-CS8's and Polk XT35's external dimensions. Sony SS-CS8 has external dimensions of 146.0 x 430.0 x 220.0mm ( 5.75 x 16.93 x 8.66inch) whereas Polk XT35 has external dimensions of 107.0 x 621.0 x 142.0mm ( 4-3/16 x 24-7/16 x 5-9/16inch) .

Polk XT35 is 39mm shorter and 78mm less deeper than Sony SS-CS8 but it is also 191mm wider.

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 Sony SS-CS8 is approximately 946.0cm2 / 146.6inch2 and base area of the Polk XT35 is approximately 881.8cm2 / 136.7inch2. The SS-CS8 requires 7% more surface area than the Monitor XT35 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 Sony SS-CS8 weighs 5.00kg / 11lbs and the Polk XT35 weighs 6.36kg / 14lbs. This makes the Monitor XT35 27% heavier than the SS-CS8.

Here is a comparison of how SS-CS8 and Monitor XT35's weights compare with the average, max and min weights in Passive Center Channel class.
