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.

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

RP-500C features Binding post type posts and Q250c has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

In this section, we are going to compare Klipsch RP-500C's and KEF Q250c's external dimensions. Klipsch RP-500C has external dimensions of 175.0 x 472.0 x 254.0mm ( 6-7/8 x 18-9/16 x 10inch) whereas KEF Q250c has external dimensions of 181.0 x 526.0 x 216.0mm ( 7-1/8 x 20-11/16 x 8-1/2inch) .

Klipsch RP-500C is 54mm narrower and 6mm shorter than KEF Q250c but it is also 38mm deeper.

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 Klipsch RP-500C is approximately 1198.9cm2 / 185.8inch2 and base area of the KEF Q250c is approximately 1136.2cm2 / 176.1inch2. The RP-500C requires 6% more surface area than the Q250c 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 Klipsch RP-500C weighs 8.18kg / 18lbs and the KEF Q250c weighs 7.50kg / 16.5lbs. This makes the RP-500C 9% heavier than the Q250c.
