Upgrading a karaoke system is a necessary solution when the old sound system starts to deteriorate: the speakers are distorted, the microphone howls, the amplifier is weak, or the sound is no longer clear and vibrant as before. According to Phuc Truong Audio's experience, after only 2-3 years of continuous use, the performance of a karaoke system can decrease by up to 30%., especially in high-intensity business karaoke rooms.

Replacing and upgrading speakers, amplifiers, digital reverbs, microphones and high-quality cables helps restore and enhance the singing experience, while integrating many modern technologies such as Bluetooth 5.0, HDMI ARC, S/PDIF and smart anti-howling features.
According to statistics from the Vietnam Audio Association in 2024, 70% of karaoke bar owners said that revenue and the number of returning customers increased significantly after upgrading their old sound systems. This is proof that investing in upgrading not only brings entertainment value but also has direct business benefits.
Why should you upgrade your karaoke system?
When using a karaoke system for a long time, the device will gradually degrade in both hardware and sound processing performance. Phuc Truong Audio's experience shows that bass speakers and amplifiers are often the fastest degrading devices, easily causing distortion and loss of power when playing music at high volume.
In addition, the need for change is also an important reason: in the past you only needed basic karaoke entertainment, but now many families want a more versatile system - singing karaoke, listening to lossless music, watching movies or even high-quality livestreaming.
Signs you need to upgrade your karaoke system
Some common signs that Phuc Truong Audio has conducted a field survey. in many customers:
- The singing often howls and is difficult to control.
- The speaker makes a distorted sound when the volume is increased.
- The vocals are drowned out by the background music and lack brightness.
- Weak bass, less detailed treble, no longer as "tight" as before.
- The room is spacious but the sound is not even, the volume is unstable.
- Background hum and signal interference due to old wiring.
According to technical standards, when Total harmonic distortion (THD) exceeds 1% then the sound will lose fidelity - this is also the milestone for you to consider upgrading the device.
Benefits of upgrading karaoke system
Upgrading your karaoke system makes a clear difference:
- More accurate sound: New generation speakers have a wide frequency range from 40Hz - 20kHz, fully reproducing bass - mid - high.
- Modern amplifier: Integrated 24bit/192kHz DAC, high-detail signal processing, solid and clear music.
- Smart microphone: Multi-level anti-howling, frequency filtering support, helps vocals to be clear and effortless.
- More versatile: Suitable for family karaoke, watching movies, listening to music, organizing small events or livestreaming.
According to an internal study by Phuc Truong Audio in 2025, 8/10 customers after upgrading said that "sound quality improved significantly, singing was lighter, bass was stronger and no more howling."
What does the karaoke system upgrade service include?
Karaoke system upgrade service does not stop at replacing speakers or amplifiers. This is a comprehensive process, including evaluating the current system, selecting suitable equipment, integrating new technology and recalibrating the whole system for maximum performance.

Replace and upgrade core equipment
Karaoke speakers are the heart of the system, so upgrading speakers is crucial. For example, replacing a 25cm bass speaker with a 30cm bass speaker helps improve the powerful bass range, suitable for rooms larger than 25m². At the same time, the amplifier or power amplifier also needs to be upgraded to ensure the ability to pull the speaker, avoiding distortion during long-term operation. With new generation digital echo or mixer, the sound is processed by an advanced DSP chip, allowing each frequency band to be adjusted precisely to each Hz, providing optimal balance.
Integrating modern technology
Today's karaoke equipment is no longer limited to traditional analog. 3-in-1 digital amplifiers can connect via Bluetooth 5.0, HDMI ARC, optical or S/PDIF, allowing for a variety of connections from TVs, laptops to smartphones. Some digital echo lines also support calibration via phone applications, making it easy for users to optimize with just a few steps. New generation anti-feedback technology uses frequency analysis algorithms to completely eliminate feedback, even in spaces with many speakers.
Check and optimize the wiring system
Many customers ignore the wires, but this is the "blood vessel" of the entire karaoke system. Low-quality speaker wires and signal wires will cause attenuation, slow down the signal and reduce sound details. When upgrading, the technician will replace the standard RCA or XLR signal wire, which is anti-interference and multi-layered, ensuring accurate signal transmission, strong and stable sound. With speaker wires, choosing the right pure copper cross-section also helps the speaker maximize its capacity.
Calibrate and set-up the entire system
After installation, the technician will measure the frequency response with specialized equipment to calibrate the sound to suit the space. EQ for each frequency range is set so that the bass is tight, the mid is clear and the treble is bright but not harsh. The microphone is set up with reasonable gain so that the vocals stand out without causing howling. Echo and reverb are also calibrated according to each music genre, from gentle bolero music to vibrant remix music, creating a professional feel like a business karaoke room.

Phuc Truong Audio's karaoke system upgrade process
To ensure quality, we have developed a 5-step upgrade process, ensuring that customers receive a stable karaoke system with perfect sound quality.

Test and evaluate current system
First, the technician will survey the home, checking the entire old system including speakers, amplifiers, digital echo, microphones, wires and room space. Each device is evaluated in detail for performance, durability and compatibility, from which an accurate report is provided as a basis for the consultation step.
Consulting on upgrade solutions
Based on the actual needs and budget of the customer, we will offer many options. For example, for a 30m² room, you can upgrade to a 30cm bass speaker combined with an active subwoofer to enhance the bass range. For customers who love technology, a digital amplifier supporting Bluetooth 5.0 and HDMI ARC is the right choice. All solutions ensure a balance between performance and cost.
Perform upgrade
After the customer chooses the option, we will proceed to replace the equipment quickly, ensuring safety and neatness. The old equipment is dismantled cleanly, the new equipment is installed according to technical standards, and simultaneously connected to the existing system.
Calibration and testing
Once the installation is complete, the technician will proceed to calibrate the entire karaoke system in detail. The EQ, echo, reverb, and delay parameters are set specifically for the room space. Then, the system is tested with many music genres: from bolero, pop music to dance, remix to ensure accurate sound reproduction, outstanding vocals, and not overwhelmed by background music.
Handover and user manual
Finally, the customer will be handed over the fully upgraded karaoke system. The technician will give specific instructions on how to use, how to connect the device, and basic operations to adjust it to their liking. In addition, Phuc Truong Audio always maintains a clear warranty policy and after-sales technical support, helping customers feel secure throughout the usage process.
Practical FAQs When Upgrading Old Karaoke Systems
Can I just replace the speaker without replacing the amplifier?
Yes, but you need to carefully consider compatibility. If the new speaker has a larger capacity (for example, a 30cm bass speaker with a capacity of 500W) while the old amplifier can only pull a maximum of 300W, it will lead to a "weak" phenomenon, easily distorting the sound or burning the capacity. On the contrary, if karaoke amplifier too strong for the speaker can easily damage the speaker. Therefore, it is best to upgrade synchronously or have a technician calculate the appropriate capacity.
Does upgrading the microphone help reduce feedback?
Yes. Wireless microphones New generations often integrate frequency filters and multi-level anti-feedback (Auto Feedback Canceller). However, howling does not only come from the microphone, but is also related to the placement of the speakers, digital echo, amplifier and signal wires. Therefore, the optimal solution is to combine upgrading the microphone + adjusting the digital echo and rearranging the speakers.
Are wires important when upgrading a karaoke system?
Very important. Poor quality cables will degrade the signal, cause background noise, and make the sound buzz or crackle. With the system karaoke system, speaker wire should be pure copper, cross-section suitable for speaker capacity (usually from 2.5mm² or more). RCA/XLR signal wire should be anti-interference, multi-layered to ensure stable signal.
Should I add a subwoofer when upgrading my karaoke system?
If you want more powerful, deep and solid bass then you should. Subwoofer (especially electric sub) helps support the bass range from 30-120Hz, bringing a more realistic karaoke experience, especially when singing remix music, EDM or watching movies. However, it is necessary to choose a sub suitable for the room area: rooms under 20m² only need a 30cm sub, rooms 30-40m² should choose a 40cm sub.
