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.
ProCenter 1000 can handle a max power of 200 watts RMS from the amp the whereas A135C has a max power handling value of 150 watts RMS, 50 watts less than the ProCenter 1000.
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
ProCenter 1000 features 5-way post type posts and A135C has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.
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 Definitive ProCenter 1000's and JBL Stage A135C's external dimensions. Definitive ProCenter 1000 has external dimensions of 124.0 x 372.0 x 127.0mm ( 4-7/8 x 14-5/8 x 5inch) whereas JBL Stage A135C has external dimensions of 105.0 x 747.0 x 186.0mm ( 4-1/8 x 29-3/8 x 7-5/16inch) .
Definitive ProCenter 1000 is 375mm narrower and 59mm less deeper than JBL Stage A135C but it is also 19mm taller.
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 Definitive ProCenter 1000 is approximately 472.4cm2 / 73.2inch2 and base area of the JBL Stage A135C is approximately 1389.4cm2 / 215.4inch2. The ProCenter 1000 requires 66% less surface area than the A135C which gives it a small advantage 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 Definitive ProCenter 1000 weighs 3.64kg / 8lbs and the JBL Stage A135C weighs 7.46kg / 16.4lbs. This makes the A135C 105% heavier than the ProCenter 1000.
Here is a comparison of how ProCenter 1000 and A135C's weights compare with the average, max and min weights in Passive Center Channel class.
