The compact size is one of the key elements of these Illuminator tweeters, which
provides a high degree of flexibility within design options. The small size is employed
without compromising sound quality where these compact tweeters are fully
comparable to the renowned full size Illuminator and Revelator tweeters, no matter if
the music is played at high or low listening levels.
