2. Understanding Frequency Response
Frequency response is a measure of how well an audio device reproduces different frequencies, typically expressed in Hertz (Hz). It indicates the range of frequencies the device can produce and the accuracy with which it reproduces these frequencies.
2.1 Frequency Range
The frequency range of an audio device is usually presented as a spectrum from the lowest to the highest frequency it can reproduce. For instance, a frequency range of 20 Hz to 20 kHz covers the audible spectrum for humans. However, the quality of reproduction within this range can vary significantly.
2.2 Frequency Response Curve
The frequency response curve is a graphical representation of how the device performs across its frequency range. It shows the level of output (in decibels) at various frequencies. A flat response curve is often desired for accurate sound reproduction, as it means the device reproduces frequencies uniformly without exaggerated peaks or dips.
3. Shure SE535 Frequency Response Analysis
The Shure SE535 is noted for its well-balanced frequency response, designed to offer an accurate and immersive listening experience. The frequency response of the SE535 is typically stated as 18 Hz to 19 kHz, a range that covers the majority of the audible spectrum. However, the actual performance can be more nuanced.

- Performance: The dual tweeters in the SE535 ensure that midrange frequencies are detailed and articulate, contributing to a rich and engaging listening experience. The midrange is neither too recessed nor overly pronounced, maintaining a natural sound balance.
3.3 High Frequencies (Treble)
The high-frequency response of the SE535 is designed to be crisp and extended, providing clarity and definition to the top end of the audio spectrum.
- Frequency Range: The SE535 extends up to 19 kHz, allowing for the reproduction of high-frequency details.
- Treble Quality: The treble is clear and well-defined, with sufficient extension to reproduce high-frequency details without excessive brightness or sibilance.
- Performance: The balanced armature drivers in the SE535 contribute to a precise and accurate high-frequency response, ensuring that cymbals, high hats, and other high-frequency elements are rendered with clarity and precision.
3.4 Frequency Response Curve
The frequency response curve of the Shure SE535 typically shows a relatively flat response across the audible range, with some slight adjustments:
- Bass Presence: The curve may show a slight boost in the lower frequencies to provide a rich and impactful bass response.
- Midrange Flatness: The midrange is generally flat, contributing to a natural and uncolored sound.
- Treble Extension: The high frequencies are extended, with a gentle roll-off at the extreme high end to avoid excessive brightness.
