The question defines irony: how does a bookshelf speaker in this class, with these dimensions, deliver sound reproduction so big? Perhaps not so ironic when you consider they are the new Series 3 Bookshelf Speakers from Pioneer.

With relentless attention to detail, these speakers were designed to satisfy both movie and music lovers. Together, clean lines and innovative features make them the quintessential speakers in their class for home theater systems, delivering the kind of high performance and outstanding quality that makes for a stunning audio experience.


Passion Translated Into Sound

Pioneer has been the industry leader in audio design and engineering firsts for over 70 years. This heritage of passion for high-end audio represents everything we have learned about accurate sound reproduction.

A descendant of our revered EX speaker line, the S-31B-LR-K incorporates some of our most advanced technology to deliver pristine sound:

Working with its unique cabinet construction, Pioneer’s exclusive ABD (Acoustic Balance Drive) and AFAST (Acoustical Filter Assisted System Tuning) sound tuning technologies work with the driver and port placement in the cabinet to eliminate vertical standing waves, resulting in precise and dynamic bass with no low midrange coloration.

It isn’t a difficult conclusion to reach. Superior sound components, materials and technology get you closer to the music and soundtrack than ever before.


Ahead of the Curve

The S-31B-LR-K speakers utilize a true curved cabinet design. So besides the aesthetics being considerably more pleasing, this stiffer design reduces standing sound waves inside the cabinet, resulting in high-performance and exceptional sound quality.

Beautiful and elegant in their own right, the speaker grills are flush-mounted to the cabinet. Beyond visually pleasing design, they also do a superior job of protecting the speaker drivers.

Place the S-31B-LR-K speakers precisely where the sound will be most appealing to you, with the optional telescoping metal CP-31B speaker stand (sold separately).
