What customers say
Customers overwhelmingly praise the MartinLogan Motion 15i speakers for their exceptional sound quality and elegant design. A key highlight is the remarkably clear and expansive soundstage produced by the compact speakers. The Folded Motion tweeter delivers crisp, articulate highs, ensuring a non-fatiguing listening experience across various music genres. Bass response is consistently noted as surprisingly deep and tight, exceeding expectations for bookshelf models. Reviewers appreciate the premium look, especially the Red Walnut finish, which complements modern decor. While positioned at a higher price, the consensus is that the superior sound performance and build quality fully justify the investment. These speakers are highly recommended for those seeking high fidelity in a stylish package.
Know before you buy
The Folded Motion tweeter uses a pleated diaphragm that moves air much faster and with less distortion than a traditional dome. This design provides a wider, more detailed high-frequency response that mimics the clarity of MartinLogan's high-end electrostatic speakers.
While they are designed as bookshelf speakers, they perform best when placed on dedicated speaker stands away from walls. If you must place them on a shelf, ensure there is enough clearance behind the unit for the rear-firing bass port to breathe, otherwise the low-end response may become muddy.
The 5.25-inch aluminum cone woofer is paired with a rear-firing bass port to maximize low-frequency output. While they provide impressive punch for their size, they are bookshelf speakers and may require a dedicated subwoofer if you are looking for deep, room-shaking bass in a large space.
These speakers are efficient and can be driven by most high-quality integrated amplifiers or AV receivers. Look for an amplifier that offers stable power delivery to ensure the Vojtko crossover network can maintain the speaker's signature clarity at higher volumes.
They are excellent for both. Because they offer a wide, detailed soundstage, they work perfectly as front-channel speakers in a home theater or as a high-fidelity stereo pair for critical music listening.
