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.
Studio 2 6IW can handle a max power of 250 watts RMS from the amp the whereas Studio 2 6IW has a max power handling value of 80 watts RMS , 170 watts less than the Studio 690.
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
Studio 690 features 5-Way post posts which make bi-amping or bi-wiring possible. Studio 2 6IW has a Spring posts which doesn't feature bi-amping/bi-wiring.
JBL Studio 690's 5-Way post terminals allows Bi-amping or bi-wiring
