How many conventional ceiling loudspeakers can be replaced by one Soundsphere Model Q-CS ceiling loudspeaker?
This question comes up every time the conversation turns to the Model Q-CS. The answer requires some discussion: The true coverage of conventional ceiling loudspeakers According to their specification sheets, most “higher-quality” ceiling loudspeakers produce a full-frequency coverage field (-6dB from on-axis) of 60°. Beyond this cone of coverage, mid, mid-high and high frequencies are attenuated. These frequency ranges are crucial to speech intelligibility and perceived “smoothness” of coverage. Ceiling loudspeaker systems should never be heard Listeners should never perceive a ceiling sound system. As listeners move around the coverage area, the sound level and frequency response should not change enough to be noticed. Conventional ceiling loudspeakers, when used conventionally, produce full-frequency sound directly under them and only low frequency sound off-axis. A listener moving from an off-axis position to directly under the loudspeaker cannot help but perceive a change in the s
