Equipment of modest quality is relatively unaffected by these issues, as the amplifier and speaker will not reproduce such low frequencies, but high-fidelity turntable assemblies need careful design to minimize audible rumble.
The choice of speaker represents a compromise: while some speakers more effectively reproduce low frequencies, they may have poorer midrange and transient response.
These drivers used a single cone made with paper at the base, reproducing low frequencies, aluminium in the middle area, and titanium at the neck zone, to produce high frequencies.
Reproducing multiple frequencies with the same diaphragm causes intermodulation distortion, a non-linear effect that occurs when one surface attempts to reproduce both frequencies simultaneously.
The new disks will be able to reproduce higher frequencies than compact disks, and the range between the loudest and the softest sounds will be greater.
They are used to supplement the sound of tweeters by reproducing frequencies which the tweeter may produce only with a narrow polar output, or perhaps with distortion.
A woofer is a driver that reproduces low frequencies.
A mid-range speaker is a loudspeaker driver that reproduces middle frequencies.
Many components, for instance, are able to reproduce frequencies higher than the limit of human hearing-20 kHz.
The crossover section may also include a high-pass "infrasonic" filter which prevents the subwoofer driver from attempting to reproduce frequencies below its safe capabilities.
