The size of your speakers make a difference in performance. While many well known speaker brands push smaller speaker concepts, THX recommends resisting the temptation to go too small. The smaller the speaker, the more you may compromise in terms of output and low frequency performance. Try to find a balance between the size you desire and the sound quality you expect. THX Certified speaker brands, such as Sonance and Atlantic Technology, are renowned for their design aesthetic, creating high performing speakers that blend with any décor.
