PSB Imagine B50 Bookshelf Speakers

Precision Sound, Size-defying Bass

The Imagine B50 bookshelf speakers deliver room-filling true-to-nature sound, underscored by an unexpectedly impressive bass performance. Featuring a 1” tweeter and a 5.25” woofer meticulously housed within a compact architectural footprint, the B50 also unveils a sophisticated 2-way bass reflex arrangement complemented by a rear-facing slot port. The B50s can be seamlessly integrated into any multi-channel or surround sound setup by placing them on the AST-25 floor stands.

Placement Flexibility

Enjoy precise sound wherever you place the B50 bookshelf speakers. Their performance-focused components offer placement flexibility, wider bandwidth, higher output, enhanced efficiency, superior power handling, reduced distortion, and a smooth tonal balance. Accuracy is maintained at all sound levels, with clarity even at lower volumes, ensuring every note resonates.

Bring your Entertainment to Life

Elevate the way you listen to your music and movies. Seamlessly adaptable to hi-fi or home theatre setups, the B50s deliver a sonic experience that captivates any listener. From cinematic soundtracks, easy music listening to whisper quiet dialogues, you can expect a level of performance that defies its compact footprint.

Refined Design

With minimalist elegance offered through a slim and compact cabinet design and neutral Satin Black and White finish options, the B50 bookshelf speakers integrate seamlessly into any space. Aluminum trim and chamfered edges not only captivate the eye but also sync perfectly with the PWM Series, creating an entertainment oasis at home.
