The Atrium 8 is the largest speaker in the outdoor range and the only one sold singly, which tells you how it is normally used: placed where coverage is needed rather than bought in twos.
Two tweeters rather than one is the unusual part. Splitting high frequencies across a pair of domes widens the angle over which treble stays audible, so a single cabinet can serve a wide area instead of aiming at one seat.
Below them a six and a half inch cone reaches into the mid forties, deep enough that an outdoor zone holds together without a buried subwoofer supporting it.
Sensitivity is the highest in the range, which matters on long cable runs and across multiple speakers on a single amplifier channel.
