When wondering if a subwoofer needs an amp, look first at the subtype. If you own a premium powered subwoofer or are thinking of getting one, you may not need an external amplifier, unless you want to push the output to extreme levels. A passive subwoofer, however, can't work without an amp.
Can I use a subwoofer without an amp?
In nearly all cases, the answer is yes. Unless you have a system in your car or boat that is already powering a subwoofer, you'll need to find an amplifier that will power your sub. Your head unit will typically provide a low-power signal (RCA output) that can be used for an amplifier to power your subwoofer.
Can you use a subwoofer by itself?
This could leave you in a state of confusion. Will a subwoofer work without speakers? Yes, with the right connection, you can achieve the low frequencies of a subwoofer without the use of a speaker system. To achieve this, use a line level RCA converter or speaker level inputs with a powered subwoofer.
Why do subwoofers need an amp?
Why Do Subwoofers Need an Amp? Subwoofers are designed to reproduce low-frequency sounds. This takes a lot of power. In designs where the subwoofer came as a part of a larger sound system, it will be properly optimized to work with the rest of the setup without showing any distortions as a result of inadequate power.
Do powered subs need an amp?
A powered subwoofer does not need an external amplifier; it has a built-in amp that supplies it with power. You will most likely connect it to the wall for its power source.
Is a subwoofer just for bass?
What is a Subwoofer? In the words of Meghan Trainor, a subwoofer is all about that bass. It's the speaker that delivers the lower frequencies – specifically 20-200 Hz – that a traditional two-channel or surround sound setup can't reproduce on its own.
Can I use any speakers with a subwoofer?
A normal speaker is not capable of producing low-frequency sound emission and hence, cannot be used as a subwoofer. Given the subwoofer's unique purpose, a normal speaker cannot replace it. You can use a woofer to achieve low bass tones, but even this does not compare to a sub.
Is subwoofer same as amplifier?
A subwoofer has impedance (measured in ohms) which represents the "load" an amplifier will sense on its output. An amplifier will put out different amounts of power (watts RMS) based on the impedance load it "sees."
Can a subwoofer power speakers?
A powered subwoofer (active subwoofer) cannot act as the power source for speakers in your sound system. While a powered subwoofer has a built-in amplifier and does not rely on an additional power source for itself, the equipment does not have a speaker input/output capacity to supply power.
