300 IW 6 features a 1" Inverted Hard-Dome Tweeter and 1 x 6.5" Flax Woofer. On the other hand, the CWM663 features a 1" Soft-Dome Tweeter and 1 x 6" Kevlar Woofer.
Frequency Response
300 IW 6 has a frequency range of 55-28kHz whereas CWM663 has a frequency range of 45-50kHz. With a minimum frequency of 45Hz, the CWM663 can go significantly deeper on the low side and provide stronger bass compared to the 300 IW 6's min frequency of 55Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the In-wall class in our database.
Low Frequency
In-wall Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
300 IW 6 and CWM663 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 300 IW 6 sensitivity is rated at 90 dB and the CWM663's is at 88 dB. This 2 dB difference makes the Focal 300 IW 6 a more sensitive speaker compared to B&W CWM663, hence will play louder with the same amount of watts.
Sensitivity
In-wall Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
CWM663 can handle a max power of 150 watts RMS, whereas 300 IW 6 has a max power handling value of 130 watts RMS, 20 watts less than the CWM663.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
300 IW 6 features Spring post type posts and CWM663 has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
