What is a Karaoke Speaker?
Karaoke speakers is a specialized type of speaker designed for use in home karaoke sound system or professional. This is an important device that plays the role of transmitting audio signals from the source and transmitting them to the listener's ears.
Unlike regular music speakers, karaoke speakers have the following characteristics:
- The design focuses on the mid-range frequency range to reproduce vocals more clearly, brightly and transparently.
- Usually have a horizontal design, while music speakers usually have a vertical design.
- Integrated sound adjustment features such as tone adjustment, echo and reverb to enhance entertainment and sound quality for singers.
- It can be a powered speaker (electrically excited speaker) with a built-in amplifier, or a regular speaker that needs to be connected to an external amplifier/power amplifier.
- 2 in 1 design for singing karaoke, watching movies and listening to music.
In general, karaoke speakers are optimized to provide the best singing experience with suitable sound quality, although they may not be as detailed as dedicated music speakers. This is an indispensable device in today's home karaoke sound systems.
Structure of karaoke speakers
The structure of karaoke speakers includes the following main parts:
- Woofer: The subwoofer is the main part of the karaoke speaker, designed to produce bass and bass sounds.
- Mid-range speaker: The midrange speaker helps to produce sound at mid-range frequencies, ensuring that vocals are transmitted clearly and vividly.
- tweeter: The tweeter helps reproduce high frequency sounds, creating sounds such as flutes, violins, etc.
- Low frequency crossover (crossover): The low-pass crossover helps divide the audio signals and send them to the respective speakers, ensuring that each speaker produces sound at the appropriate frequency.
- Enclosure: The speaker enclosure is the part that contains the different parts of the speaker, helping to isolate sound and reduce outside noise.
- Audio controls: Some karaoke speakers are equipped with sound adjustment features such as tone adjustment, echo and reverb to enhance the entertainment and sound quality for users.

- Karaoke speaker with power: Powered speakers (also known as electric speakers) are speakers that have a built-in amplifier in the same housing as the speaker, allowing the speaker to operate without connecting to an external amplifier. Using powered speakers, you will not need to buy an additional amplifier, because it is already integrated inside, this helps save some costs, but in return the speaker is quite expensive.
- Regular speakers: This is the type of speaker that you can see in almost all home karaoke systems. Because this is a popular speaker line, it usually does not have integrated power, and must use a power amplifier or amplifier to operate.
How to connect multiple Karaoke speakers at the same time to the amplifier
It is easy to connect 2 pairs of speakers (4 speakers) to a 1-channel power amplifier. You do not need to calculate the impedance when connecting 2 speakers to 2 power channel. There are 1 most popular ways to connect 3 speakers and a 4-channel power amplifier: direct connection, parallel connection, and adding resistors and circuits. Each method will have its own advantages, limitations, and implementation methods.
Method 1: How to connect 4 speakers to a 2-channel amplifier in parallel
Prepare speaker wire and jacks for connection.
How to do it specifically:
- You take the positive poles of the two speakers and connect them together, and the two negative poles and connect them together. When connecting, pay attention to the correct polarity to ensure effectiveness. If you connect the wrong polarity, they will cancel each other out. Then the bass of the speaker will be lost, and the sound from the speaker will not be good.
- When connecting 4 speakers and a 2-channel amplifier in parallel, for example, 2 speakers with an impedance of 8 Ohm will have 4 ohm left. The power will be equal to the total power of the 2 speakers.
- Do the same with the other pair of speakers you need to use. When you connect them exactly this way, the sound from the speakers will be very good. You won't feel them weaker or less when playing.
Method 2: How to connect 4 speakers to a 2-channel amplifier in series
Unlike the method of connecting 4 speakers to a 1-channel amplifier in parallel, with this serial connection method you only need to perform the following steps:
- The negative terminal of this speaker is connected to the positive terminal of the other speaker. The remaining positive and negative terminals will be connected to the 2-channel amplifier. You do the same with the remaining pair of speakers.
- When connecting 2 pairs of speakers and a power amplifier, you will increase the impedance of the speakers, and the power amplifier will not overheat when operating. However, due to the series connection, the power of the power amplifier will be divided into 2 pairs of speakers. Thus, both the volume and power of the speakers will not be able to be used. The sound output is also not as good as the connection method above.
Based on our many years of experience, we recommend that you choose to connect 2 pairs of speakers to the amplifier in parallel because this will ensure the strongest, most powerful and best sound.
However, when connecting 4 speakers to 1 amplifier in parallel, the resistance of the speakers and amplifier may not match. Don't worry, just follow the solution to the situation by adding a capacitor to the device.
Method 3: How to connect 2 pairs of speakers to the amplifier by adding resistors to the connecting circuit
How to connect 2 pairs of speakers to the amplifier by adding resistors to the connecting circuit is done as follows:
When connecting 4 speakers in parallel but the impedance is low, for more peace of mind during use, you can add a 3ohm impedance capacitor in series with the speaker. This will increase the impedance and make the safest connection.
Some notes when connecting 4 speakers and 2-channel amplifier
To perform the most accurate way to connect multiple speakers to the amplifier, please note the following:
- The 2-channel amplifier must have enough capacity to be able to load 4 speakers before you can make the connection. If the power output is low, you should not do so, as it will cause the speakers to not output at their full capacity, the amplifier will not perform its role properly, or even break down or burn out. Instead, you can invest in a 4-channel amplifier to ensure maximum safety.
- You need to clearly determine which 4 channels you will connect the 2 speakers to, parallel or series to wire them correctly. Pay special attention to the wires to connect them correctly.
- Use quality Neutrik speaker cables and jacks to ensure that the audio signal is transmitted stably and at its best.
- After connecting, before playing test music, turn the volume to 0, then play music and slowly adjust the volume to your liking.
Frequently Asked Questions (FAQ) Section:
What type of speaker wire and plug is best for a karaoke system?
To ensure the best sound quality, use speaker wire with a large cross-section, usually 14 AWG or larger, to minimize signal loss. Neutrik plugs are a popular choice due to their durability and reliable connection. Make sure the wire and plug are rated for the power of your system.
How to check and maintain the sound system after connection?
After connecting, test each speaker by playing music at a low volume, then gradually increasing it to ensure there is no distortion or loss of sound. Regularly check the wire and plug connections to ensure they are not loose. Clean the speaker and plug surfaces periodically to prevent dust from affecting the sound quality.
What are common speaker connection problems and how to fix them?
Some common problems include distorted sound, no sound coming from the speakers, or the amplifier overheating. To fix this, double-check the wiring to make sure it is not misaligned. If the amplifier is overheating, it may be due to a mismatch in speaker impedance; consider adding resistors to adjust the impedance. If the sound is distorted, check that the amplifier is driving enough power to drive the speakers.
