What Are the Main Advantages of a Concentric Driver?
Concentric drivers align the tweeter and woofer in one compact unit, improving sound consistency and imaging across the room. This design offers clearer, more uniform audio regardless of listener position or room acoustics.
What is a Concentric Driver?
A concentric driver is a specialized speaker design where the tweeter is mounted directly at the center of the bass or midrange cone, effectively combining the two into a single, compact unit. The tweeter sits at the apex of the cone—right where the dust cap would typically be—positioned on top of the bass driver’s pole piece.
Benefits of a Concentric Design
The unique alignment of drivers in a concentric configuration offers several key performance advantages:
-
Improved Off-Axis Response
Because the sound from both the tweeter and woofer originates from the same point, the speaker delivers more uniform sound across a wide listening area. This helps ensure clarity and tonal balance even when you’re not seated directly in front of the speaker.
-
Superior Imaging
The time alignment of the tweeter and woofer leads to more accurate soundstage and imaging, allowing instruments and vocals to appear more naturally placed in the stereo field.
-
Greater Consistency Across Rooms
Concentric drivers are less influenced by room acoustics, making them an ideal choice for spaces where perfect speaker placement is difficult. This design helps maintain consistent sound character regardless of the room layout.
-
Compact Design
Combining two drivers into a single assembly also helps save space and allows for more flexible cabinet designs, which can be useful in both home audio and custom installations.
Conclusion
Concentric drivers, like those found in select ELAC speakers, provide a significant upgrade in sound dispersion, imaging, and consistency. They deliver a more natural and immersive listening experience—wherever you are in the room.
