Sound Review:
The MartinLogan Motion 4i is a compact bookshelf speaker that delivers exceptional performance for its size. Featuring MartinLogan’s signature Folded Motion Tweeter, it offers crisp, detailed highs and smooth mids, making it ideal for both music and home theater applications. Despite its small form factor, the Motion 4i provides impressive clarity and a surprisingly full soundstage, although pairing it with a subwoofer is recommended for deeper bass. Its sleek, curved design allows for flexible placement options, whether mounted on a wall or placed on a shelf. A fantastic choice for those seeking high-quality sound in a compact and elegant package.
