Why Do Some ELAC Speakers Extend Beyond 20kHz?
ELAC designs tweeters to extend beyond 25kHz to ensure accurate, high-quality performance up to 20kHz, where many standard tweeters have already started to roll off. This results in clearer, more detailed sound within the audible range.
Many ELAC speaker models list frequency specifications that extend beyond the commonly accepted upper limit of human hearing, which is around 20kHz. So why design speakers to exceed this range?
Understanding Frequency Specifications
The frequency range listed in speaker specifications typically marks the points where the speaker’s output begins to diminish—often measured at the point where it drops by 3dB. For many dome tweeters rated up to 20kHz, the output has already begun rolling off significantly as it approaches that upper limit.
The ELAC Advantage
By engineering our tweeters to extend well beyond 25kHz, we ensure that the performance remains strong and accurate up to and through 20kHz. This results in a smoother high-frequency response and helps preserve detail, air, and clarity in the sound—even within the audible range.
Bottom Line
Extending the tweeter’s range past 20kHz isn’t just about reaching higher frequencies—it’s about maintaining better performance within the range you can actually hear.
