JBL Synthesis 4349

While the 4349 is built to professional studio standards, it is designed specifically for home audio environments. Its classic aesthetic and adjustable sound controls make it a versatile choice for high-end residential listening rooms.

These controls allow you to fine-tune the high-frequency output to match your room's specific acoustics. If your room is overly reflective or 'bright,' you can dial back the treble to achieve a more balanced and comfortable sound.

With a sensitivity of 91dB, these speakers are relatively efficient and can be driven well by amplifiers ranging from 25W to 200W RMS. However, using a high-quality amplifier within this range will ensure you get the best dynamics and control from the 12-inch woofer.

Yes, the JBL 4349 features dual sets of input terminals, allowing for both bi-wire and bi-amp configurations. This provides flexibility if you prefer to separate the signal paths for the woofer and the compression driver.

Each speaker weighs 37.7kg and measures roughly 737mm tall by 445mm wide. Given their size and bass-reflex design, they perform best when placed on sturdy stands—ideally the optional tilt-back stands—with enough clearance from walls to allow the rear port to breathe.

The 12-inch woofer is engineered for high output and low distortion, delivering a deep, punchy, and articulate bass response. It provides a solid foundation for the music, maintaining clarity even at higher volumes.
