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
In-wall Speakers is a 8 ohms speaker compared to the Phantom H-50 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. In-wall Speakers sensitivity is rated at 89 dB and the Phantom H-50's is rated at 88 dB. This 1 dB difference makes the Sonos In-wall Speakers a more sensitive speaker compared to DALI Phantom H-50, 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.
In-wall Speakers can handle a max power of 130 watts RMS from the amp the whereas Phantom H-50 has a max power handling value of 120 watts RMS, 10 watts less than the In-wall Speakers.
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
In-wall Speakers features Spring post type posts and Phantom H-50 has a Spring 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.
