Drivers
One of the fundamental differences between these two speakers is that 100 IW LCR5 is a 2-way design whereas the 300 IW6 LCR is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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
100 IW LCR5 and 300 IW6 LCR have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 100 IW LCR5 sensitivity is rated at 90.5 dB and the 300 IW6 LCR's is at 92 dB. This 1 dB difference makes the Focal 300 IW6 LCR a more sensitive speaker compared to Focal 100 IW LCR5, 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.
100 IW LCR5 can handle a max power of 150 watts RMS from the amp the whereas 100 IW LCR5 has a max power handling value of 120 watts RMS , 30 watts less than the 300 IW6 LCR.
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
100 IW LCR5 features Spring post type posts and 300 IW6 LCR has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
Physical Specs
