How to connect a powered subwoofer to passive speakers? If not, dive into this article, in which we have compiled three workable tips to do so.

Whatever the characteristics of the speakers are, they fall into one of two categories: passive or active.

Their connection to the amplifier distinguishes them. Most speakers on the market are passive, requiring ordinary speaker cable to connect them to an amp. 

The subwoofer is usually an active speaker in most modern sound systems. So, how to connect a powered subwoofer to passive speakers?

This article will show you the method to do so using some easy tips.

The Difference Between A Powered And A Passive Subwoofer

Active And Passive Speakers

Understanding the differences between models of subwoofers and how they react with the remainder of your audio equipment can help you better comprehend the connections you’re trying to make when setting up the sound system in your house. 

Understanding the difference between passive and powered subwoofers, in particular, is critical to know how to use them in your house’s sound system.

Your powered subwoofer includes an integrated amplifier that provides the power required to play limited audio emissions. 

On the other hand, passive subwoofers don’t have this constructed feature and depend heavily on an external amplification for authority. 

Moreover, you must understand that when you use an active subwoofer, your amplifier does not supply your subwoofer; it would if you employed a passive subwoofer instead. 

This feature is advantageous for the rest of your surround sound machinery since you can connect the additional amplifier directly to the active speakers, providing power to them. 

Even yet, there are advantages to both passive and powered subwoofers, and one is not always superior to the other.

On the other hand, most audiophiles like the convenience of utilizing powered subwoofers without attaching them to an amplifier in their system. 

This growth in popularity since employing a powered amplifier with its integrated amplifier requires fewer connecting components to acquire and set up. You may connect a powered or passive subwoofer to the speaker feedback connection about other speakers. 

It does not, however, imply that the powered subwoofer is powering your linked active speakers. This link strips and transfers them to the subwoofer for distribution rather than sending moderate audio impulses to the speakers. 

Instead of connecting these sound equipment to transfer power between the subwoofer and speaker, you’ll link them so that the excellent signal may be “broken down” and given to the appropriate speakers based on the device’s mission. 

In this scenario, the powered subwoofers could “take” the lower frequencies bass tones while the speakers played the rest.

Even unless you aren’t confident in understanding the differences between active and passive subwoofers, you may be confused about how these differences influence the sorts of speakers that can connect to your sound source. 

And besides, the powered subwoofer’s integrated amplifier changes where the sub gets its power, so what else can it change?

Surprisingly, you may use the active and passive subwoofer. 

However, because the powered subwoofer’s integrated amplifier does not give power to the external amplifier, you need to link a dedicated amplifier to the speakers to provide them with lots of energy sources.

It emphasizes the necessity of having an additional power supply ready to be used with your loudspeakers, whatever of the subwoofer kind. 

While you want to link the subwoofer and speakers, it’s not a power source; instead, it’s a means to help the sound system’s components work together better. 

Building a high-quality sound experience with a surround audio system requires a strong connection between the speakers, subwoofers, and amplifiers. 

That’s where science and art come together to create an unforgettable sound experience for you, your family, and your friends. That’s why it’s so important to have these connections right for the entire audio experience. 

For example, you must check that each device is receiving sufficient power, that audio signals are being delivered and received correctly by each piece of equipment, and that each subwoofer is placed optimally for the speaker. 

You may then enjoy the audio experience as you intended after this coherent arrangement has been achieved.

How To Link Passive Speakers To A Powered Subwoofer?

Working with electronics may be scary at times if we are unfamiliar with it. Typically, you will end up enlisting the assistance of an expert to handle a primary task. 

If you’re having trouble connecting the powered subwoofer to passive speakers, don’t sweat it! The following are the three most straightforward tips for connecting the powered subwoofer to passive speakers.

#1. Use Stereo RCA

If a signal from an LFE subwoofer isn’t compatible with an amp or converter. It’s also possible that the subwoofer has no LFE response. Instead, the left and right RCA connections on the subwoofer may be linked. 

Alternatively, they could have the spring hooks seen on the backs of specific standard speakers. Check to see if the amplifier has an ‘Out’ RCA terminal and the sub has a ‘Line In’ coming with RCA wires to connect them. 

Connect both the right and left ports if the subwoofer’s line has a divide or a Y-connector for left and right stations. Remember to plug in the receiver’s RCA terminal if there are two RCA connections for sub output on the amplifier.

You may connect the receiver’s speaker signal to the subwoofer’s construction if it includes spring clips for using speaker wire. This procedure is the same as attaching a standard stereo speaker. 

Connect the receiver’s network to the sub as the loudspeaker if one pair of spring clips. Instead of partially covered wire, you can use banana hooks to connect every system’s backs.

#2. Use An LFE

The ideal way to integrate a sub is to employ an LFE through the speaker’s sub output, often known as “Subwoofer” or “Sub Out”. 

All audio mechanism receivers and specific stereo speakers provide this type of subwoofer output. The LFE path is a secondary output for subwoofers alone; it means ‘Subwoofer’ rather than LFE. 

The station audio format found on DVDs and cable TV will have a dedicated bass-only sound signal that a subwoofer can better reproduce. 

It  permits the receiver/LFE amp or sub output connection to the subwoofer’s ‘LFE In’ or “Line In” port. Overall, it is merely a cable with regular RCA sockets.

#3. Use XLRs

It is a better solution if the speakers and subwoofer accept the jack wires. In reality, 3.5 mm connectors (known as XLR connections) are better than RCA in terms of sound quality. 

But, once again, both devices must support it for this to function; assuming your equipment is not too ancient, we’re guessing it will come with jack connectors and cables.

How To Choose The Best Powered Subwoofer For Passive Speakers?

How To Choose The Best Subwoofer?

Subwoofers are a sort of speaker that can reproduce the lowest frequency audible. The best subwoofer depends on the room’s features as well as your preferences.

Here’s how to pick the right subwoofer for your surround sound system.

Down-Firing And Front-Firing Subwoofers

Front-firing or side-firing subwoofers have a sound that comes from the front of the enclosure or the side. The sound from these subwoofers is directed downward to the floor. 

Both kinds provide comparable outcomes. Because subwoofers recreate non-directional profound frequencies, human ears can’t determine which way the music is coming from. 

Front-firing subwoofers, on the other hand, are generally situated toward the front of the room. When positioned in a sidewall or corner, down-firing subs produce the most satisfactory results.

Passive Radiators And Ports

Some subwoofers feature an extra port that allows more air to escape, resulting in a more effective bass response than the sealed ones.

Other enclosures, rather than a port, utilize a passive reflector to the speaker to improve efficiency and precision. 

You can use a flat panel or a speaker without the armature coils as a passive reflector. A passive radiator responds to the powered subwoofer driver’s airflow rather than bouncing directly from the electrically transferred audio output. 

The passive radiator boosts the subwoofer’s low-frequency output by complementing the active driver’s activity.

Wired Or Wireless

Wireless connection is becoming more common in powered subwoofers. The ability to link wirelessly between the receiver and the subwoofer eliminates a long connecting cord requirement. 

A transmitter device connected to the sub outputs of any home theater receiver is generally included with a wireless-enabled sub.

The wireless subwoofer receives low-frequency sound signals from the transmitter linked to the home theater receiver. 

As a result, the subwoofer’s wireless reader allows the integrated amplifier to supply the speaker driver, resulting in the required low-frequency sound.

Final Thoughts

Not all subwoofers are as simple and easy as this one. There are numerous options for connecting a subwoofer to a receiver, a home theater system, or an amplifier. This post has covered all you need to know about how to connect a powered subwoofer to passive speakers.
