Key Takeaways

TLDR Summary: The Bowers & Wilkins 607 S2 Anniversary Edition and MartinLogan Motion 4i are standout bookshelf speakers in their class. The 607 S2 continues B&W's legacy with refined drivers and improved crossovers, offering a warm, balanced soundstage. In contrast, the Motion 4i features MartinLogan's acclaimed Folded Motion tweeter, delivering precise highs and a wide sound dispersion. While the 607 S2 impresses with lush midrange detail suited for varied genres, the Motion 4i excels in clarity and spatial accuracy, catering to audiophiles who crave a high-resolution listening experience. Choosing between them hinges on personal taste in sonic character and room aesthetics.

Speaker Comparison

When we delve into the world of high-fidelity sound, the conversation inevitably turns to the craftsmanship of bookshelf speakers. In this arena, two names stand out with their latest offerings: the Bowers & Wilkins 607 S2 Anniversary Edition and the MartinLogan Motion 4i. Both speakers promise an enriching audio experience but cater to slightly different audiophile sensibilities. The 607 S2, a part of B&W's prestigious 600 series, celebrates decades of acoustic innovation, while the Motion 4i continues MartinLogan's legacy of blending traditional speaker design with their signature Folded Motion tweeter.

Design and Build Quality

The Bowers & Wilkins 607 S2 Anniversary Edition speakers boast a classic design aesthetic with clean lines and a minimalist finish, available in matte black or white. Their stout stature and robust construction speak of durability and quality. The MartinLogan Motion 4i, on the other hand, presents a more modern silhouette with its curved top and the distinctive perforated steel grille that protects its unique tweeter. It's available in a luxurious high-gloss black or white to match contemporary decors. Both sets of speakers feel solid and well-engineered, exuding a sense of lasting value.

Sound Characteristics

When we talk about sound, the 607 S2 speakers deliver Bowers & Wilkins' signature warm and balanced profile, with a focus on clarity and depth. The Anniversary Edition has seen an upgrade in crossover design, which translates into a more cohesive soundstage and precise imaging. The Continuum cone technology ensures articulate midrange performance that B&W fans have come to love. In contrast, the MartinLogan Motion 4i bookshelf speakers offer an exceptionally detailed and transparent sound, thanks in no small part to their Folded Motion tweeter. This tweeter provides a lightning-fast response with minimal distortion, making these speakers excellent for nuanced vocal and instrumental renditions.

For bass enthusiasts, the 607 S2 may hold the edge with its larger 5-inch bass/midrange driver. The low end is punchy and more pronounced, suitable for diverse genres of music. MartinLogan's Motion 4i, with a 4-inch woofer, still manages to deliver tight and accurate bass, but it may lack the visceral impact of the 607 S2 in larger rooms or for bass-heavy tracks without the assistance of a subwoofer.

Spatial Performance

One of the most captivating aspects of listening is the spatial representation of music. The 607 S2 speakers produce a wide and deep soundstage, allowing each instrument to occupy its own space. The placement is precise, creating an immersive listening experience that can sometimes make you forget you're in your own living room. The MartinLogan Motion 4i speakers, while offering excellent imaging, shine in delivering an airy and open soundstage. The Folded Motion tweeter's ability to disperse high frequencies with remarkable precision gives these speakers a sense of spaciousness that is hard to find in other bookshelf speakers in this class.

Compatibility and Versatility

Utilitarian considerations matter as well. The B&W 607 S2 is relatively easy to drive, meaning they will pair well with a wide range of amplifiers and receivers, making them a versatile choice for both entry-level and experienced audiophiles. The MartinLogan Motion 4i, while also not particularly power-hungry, tends to reveal its full potential with high-quality amplification due to its revealing nature. Both speakers are well suited for stereo setups, and they can also serve as part of a larger home theater system.

In sum, the Bowers & Wilkins 607 S2 Anniversary Edition and the MartinLogan Motion 4i bookshelf speakers represent two different philosophies in sound reproduction. The choice between them may come down to personal preference: whether you're after the warm and rich sound of the 607 S2 or the detailed, articulate performance of the Motion 4i. Regardless of the path you choose, both speakers are capable of delivering delightful auditory experiences that can transform your music listening into a truly transcendent endeavor.
