High Frequency
In-wall Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
255C-RT and Stage 260W have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 255C-RT sensitivity is rated at 90 dB and the Stage 260W's is at 87 dB. This 3 dB difference makes the Polk Audio 255C-RT a more sensitive speaker compared to JBL Stage 260W, hence will play louder with the same amount of watts.

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.
255C-RT can handle a max power of 150 watts RMS from the amp the whereas Stage 260W has a max power handling value of 100 watts RMS, 50 watts less than the 255C-RT.
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
255C-RT features Spring clip type posts and Stage 260W has a Spring clip type posts. None of these speakers feature bi-amping/bi-wiring.
