What is the resonant frequency of a subwoofer?
Frequency range and frequency response The typical frequency range for a subwoofer is between 20–200 Hz. Professional concert sound system subwoofers typically operate below 100 Hz, and THX-certified systems operate below 80 Hz.
What is the lowest frequency for subwoofer?
But first, what is sub-bass? Now, based on what we’ve just discussed, sub-bass is a very low frequency that ranges from 20Hz to around 160Hz. The best sub-bass frequency starts at around 60Hz and goes down to around 20Hz.
Do speakers have a resonant frequency?
A speaker will have a resonant frequency at which it is most efficient at converting the input electrical power to audio output power.
What determines the resonant frequency of a speaker?
With a loudspeaker, the mass of the moving parts, and the stiffness of the suspension (surround and spider) are the key elements that affect the resonant frequency.
Can you hear 30Hz?
Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. The volunteers were exposed to a frequency of 30 Hz for 90 seconds.
Is 30Hz good for subwoofer?
A subwoofer should certainly offer useful response to below 30 Hz. It wouldn’t be unusual for a respectable subwoofer to approach 10\% distortion at 90 dB and 30 Hz with little audible effect. If distortion goes much higher, however, the bass could turn boomy, the sub might become more localizable, or both.
What is frequency response of a speaker?
A speaker’s frequency response, measured in Hertz (Hz) tells you how accurately it converts the frequencies of an input signal. It’s common to see specs such as 60 Hz to 18 kHz. This means that it can transduce frequencies in that range with a certain degree of accuracy.
What does FS mean on a speaker?
Fs. This parameter is the free-air resonant frequency of a speaker. Simply stated, it is the point at which the weight of the moving parts of the speaker becomes balanced with the force of the speaker suspension when in motion.
What is the resonant frequency of a speaker?
The resonant frequency of the speaker (read: driver + cabinet + room acoustics) only refers to a sensitivity around a certain hz. The sound reproduced at frequencies lower than Fs are not necessarily better or worse than those above Fs.
Why do subwoofers have such high Fs?
In fact, some subwoofer manufacturers set an artificially high Fs (above true sub frequencies) just to avoid having to “tune” around this issue. Of course, this brings other issues into play, such as frequency rolloff and phase.
What is resonance and frequency?
Resonance is the phenomenon at which natural frequency coincides with the driving force and gives the maximum response. The resonant frequency is the frequency at which resonance happens. Resonance occurs in electrical systems when the system contains at least one inductor and one capacitor.
What determines the frequency of sound an object makes?
That’s the frequency that the object will sound, or resonate, when struck. A lightweight object will generally have a higher resonant frequency than a heavy object. The weight of the object, however, is not the only determinant of resonant frequency as the density of the object also contributes a role.
