PSB Imagine B50 in Japan
The PSB Imagine B50 loudspeaker is a standout in the crowded market of bookshelf speakers, offering a compelling blend of performance, design, and value. Priced at $699 per pair, it is positioned as an entry-level offering in PSB’s Imagine series, yet it incorporates advanced technologies and design principles borrowed from the brand’s flagship Synchrony series. This review delves into the speaker’s design, sound performance, and overall value, providing a comprehensive analysis of why the Imagine B50 is a worthy contender for audiophiles and casual listeners alike.
Design and Build Quality
The PSB Imagine B50 boasts a sleek, minimalist design that is both visually appealing and acoustically functional. Measuring 6.75” W x 11.8” H x 9.8” D, the compact cabinet is available in Satin Black or Satin White finishes, making it versatile enough to blend into any room decor. The satin finish, while elegant, is prone to fingerprints, requiring occasional cleaning to maintain its pristine appearance.
The speaker features a 2-way bass reflex design with a rear-facing slot port, which aids in extending the bass response down to an impressive 45Hz (-3dB). The driver complement includes a 1” titanium dome tweeter with ferrofluid cooling and a neodymium magnet, paired with a 5.25” woven carbon fiber woofer. This combination ensures a balanced frequency response and efficient power handling.
One of the most distinctive design elements is the placement of the woofer above the tweeter. This configuration tilts the in-phase lobe of the sound wave upward, optimizing the listening experience for seated listeners at an ear height of 36” to 39”. PSB recommends using 24” stands to achieve this ideal listening position, though the speakers perform well even without them.
The build quality is excellent, with a low-resonance MDF cabinet and extensive internal bracing to minimize unwanted vibrations. The rear panel features dual 5-way gold-plated binding posts, allowing for bi-wiring or bi-amping, a rare feature at this price point.
Sound Performance
The PSB Imagine B50 delivers a sound signature that is neutral, detailed, and engaging, making it suitable for a wide range of musical genres and listening environments.
Frequency Response and Imaging
The speaker’s frequency response is rated at 60Hz–20kHz (±1.5dB), with a claimed bass extension down to 45Hz (-3dB). This is remarkable for a bookshelf speaker of its size, allowing it to reproduce deep bass notes with authority. The bass is tight and controlled, avoiding the bloated or muddy sound often associated with smaller speakers.
The midrange is where the Imagine B50 truly shines. Vocals and instruments are rendered with exceptional clarity and naturalness, thanks to the seamless integration of the woofer and tweeter via a 4th-order Linkwitz-Riley crossover at 2200Hz. This crossover design ensures a smooth transition between drivers, minimizing phase issues and delivering a cohesive soundstage.
The titanium dome tweeter provides airy and detailed highs, though some listeners may find it slightly bright at higher volumes. This can be mitigated by careful placement or toe-in adjustments. The speaker’s horizontal directivity is excellent, ensuring a wide sweet spot and consistent sound quality across different listening positions.
Dynamics and Power Handling
The Imagine B50 handles dynamic passages with ease, making it well-suited for both quiet acoustic tracks and high-energy rock or electronic music. At moderate listening levels, the speaker remains distortion-free, with a smooth tonal balance. However, at very high volumes (above 95dB), some cabinet resonance becomes noticeable, particularly in the lower midrange. This is a minor quibble, as most listeners are unlikely to push the speakers to such extremes.
Soundstage and Imaging
The speaker’s ability to create a wide and immersive soundstage is one of its standout features. Instruments and vocals are precisely placed within the soundstage, with excellent depth and layering. This makes the Imagine B50 a great choice for both stereo listening and home theater applications.
Setup and Placement
The PSB Imagine B50 is remarkably easy to set up, requiring minimal tweaking to achieve optimal performance. We recommends placing the speakers on 24” stands, with the tweeter at ear level. However, the speakers perform well even on shorter stands or bookshelves, thanks to their forgiving directivity.
The rear-firing slot port requires some clearance from the wall (approximately 6–12 inches) to avoid bass buildup. Experimenting with toe-in can help fine-tune the soundstage and treble response to suit individual preferences.
Conclusion
PSB Imagine B50 offers exceptional value for money. The inclusion of bi-wiring capability and the use of high-quality materials further enhance the speaker’s appeal. It is a testament to PSB’s commitment to delivering flagship-level performance at an affordable price. The PSB Imagine B50 is a remarkable achievement in the world of bookshelf speakers. Its combination of neutral sound, deep bass extension, and elegant design makes it a versatile choice for both music and home theater enthusiasts. While it has minor limitations, such as cabinet resonance at high volumes and a slightly bright treble, these are outweighed by its overall performance and value.
For those seeking a compact, high-performance speaker that doesn’t break the bank, the PSB Imagine B50 is an excellent choice. It embodies PSB’s philosophy of delivering “True to Nature” sound, making it a worthy addition to any audio system.
