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.

603 S3 can handle a max power of 200 watts RMS from the amp the whereas Borea BR09 has a max power handling value of 170 watts RMS, 30 watts less than the 603 S3.

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

603 S3 features Binding post posts which make bi-amping or bi-wiring possible. Borea BR09 has a Binding post which doesn't feature bi-amping/bi-wiring.
