Description
S 3900
15-inch (380mm) 2-way Floorstanding Studio Monitor Loudspeaker
Key Features
25 – 250 watts suggested amplifier power range
JBL engineers have designed the S3900 for serious audio output. It’s recommended that it be powered with a separate AVR or amplifier that can deliver up to 250 watts, whether you
Are you using the speaker as a stand-alone unit or as part of a stereo/surround-sound system?
Dual 10″ (250mm) low-frequency transducers for low-distortion, natural sound
The S3900’s dual 10-inch (250-millimeter) pulp-cone woofers deliver deep, crisp bass that will not degrade at any listening level. You’ll hear low frequencies with clarity, power, and low distortion.
1-3/4″ (50mm) high-frequency transducer for crystal-clear highs
The S3900’s 1-3/4-inch (50-millimeter) Aquaplas-treated compression driver provides exceptional high-end response with low distortion. You’ll experience natural, realistic tones from all your music and movies.
3/4″ (19mm) ultrahigh-frequency transducer for extreme highs
We’ve built the S3900’s 3/4-inch (19-millimeter) ultrahigh-frequency compression driver from pure titanium. It reproduces crystal-clear, ultrahigh frequencies quickly, accurately, and without strain or distortion – even when you crank up the volume.
Extremely smooth and wide frequency response
With a frequency response of 33Hz – 40kHz, the S3900’s sound reproduction is extremely smooth and extended in every direction. The system’s directivity and power response are highly uniform, its harmonic distortion is reduced to inaudible levels, and its dynamic linearity is unparalleled.
Rear-mounted port for extended bass response
A rear-mounted port in the S3900 provides optimal low-frequency tuning for extended bass response without adding boominess or unwanted coloration in your audio.
Patented JBL Bi-Radial horn
The S3900 high- and ultrahigh-frequency drivers are mounted in patented JBL Bi-Radial horns for rich, stable stereo imaging and a wide, sit-anywhere soundstage. JBL engineers first developed the Bi-Radial horn for audio professionals and their studios. Now,
You can have the exceptional Bi-Radial sound at home.
Bi-wiring capabilities
The S3900’s internal dividing network enables bi-wiring capabilities that offer you more flexibility in amplifier selection − and serious sonic advantages in the audio response
