Introducing the JBL® S3900, a dual 10-inch (250-millimeter), floorstanding speaker ideal for two-channel and multichannel home theater systems.


Leveraging professional-grade components and taking design cues from the legendary K2® S9900, the S3900 is an audiophile’s dream come true. Hear it as the pros hear it. The JBL® S3900 puts a new spin on the praised JBL K2 S9900. Like its acclaimed sibling, the S3900 delivers your HD media in all its glory – you’ll feel as if you’re sitting in the studio with the engineers and artists. Dual 10-inch (250-millimeter) pulp-fiber cone woofers deliver lows as deep as 33Hz; a 1-3/4-inch (50-millimeter) Aquaplas-coated, pure-titanium driver delivers mids and highs with lifelike dynamics and startling realism; a 3/4-inch (19-millimeter) ultrahigh-frequency transducer reproduces frequencies up to 40kHz with extreme clarity. From your lows to highs, you won’t miss a sound. Ready to be used as part of a two-channel or surround-sound system, the S3900 looks as beautiful as it sounds with its handsome, elegant design.
