Detailed review of APlus A-B04 speaker set

To understand why APlus A-B04 popular in high impedance public address systems, we will take a deep look at each important aspect: from physical design, sound reproduction performance, ease of installation to the ability to coordinate with other audio devices in the system.

Compact design – Optimized for all types of modern technical ceilings

APlus A-B04 ceiling speaker Designed with a minimalist yet sophisticated philosophy, focusing on practicality when installed and aesthetic efficiency when used in interior spaces. With an overall size of Φ200 x 67 mm, this is one of the models with an ultra-thin speaker body, helping to fit in areas with limited technical ceiling depth such as plasterboard ceilings, aluminum ceilings or plastic ceilings.

The entire speaker body is made of high-quality ABS plastic, which is durable, lightweight, fire-resistant and can withstand moderate humidity in a closed environment. The surface is finished in neutral white, easily blending into common ceilings, maintaining the uniformity of interior design without causing confusion or disrupting the spatial layout.

The protective mesh surface is powder coated to increase durability against oxidation, prevent peeling over time and limit dust accumulation, helping the speaker maintain its new shine even after long-term operation.

Flexible capacity, customized according to area and purpose of use

APlus A-B04 ceiling speaker Designed with two output power levels of 3W and 6W, allowing users to choose according to different areas of use. In small spaces or with low background noise such as offices, classrooms, internal corridors, 3W power is enough to ensure clear sound, not harsh and save energy.

On the contrary, in larger areas or with a need for louder sound such as waiting areas, factories or apartment lobbies, the 6W level helps the sound to be emitted fully and clearly without having to increase the amplifier's power too much. This ability to adjust the power is also a plus point that helps the A-B04 easily adapt to many system layouts.

70V/100V Input – High impedance standard for building audio systems

APlus A-B04 ceiling speaker using 70V/100V input voltage system, which means operating in high impedance system (High Impedance) - a common standard in public address sound solutions. The biggest advantage of this system is that it allows connecting many speakers in the same line without affecting the sound quality, even when pulling the wire hundreds of meters away.

Hence, APlus A-B04 become the ideal solution for projects such as office buildings, high-rise apartments, schools, hospitals or large-scale factories. The ability to coordinate well with high-impedance amplifiers, zone microphones or zone division systems makes the speaker easy to integrate into complex sound systems.

Perfect frequency range, clear voice and background music reproduction

Speaker APlus A-B04 capable of reproducing sounds in the frequency range of 110Hz to 15kHz, focusing on the mid and high ranges – where the energy of voices and soft instruments is contained. This is the ideal frequency range for internal announcements, automated messages, or soft background music.

Moderate bass levels keep voices from becoming muddy, while highs are clear enough to make out every word and message, even in low-noise environments. With audio processing that focuses on the essential information, APlus A-B04 Not only does it serve well for announcement purposes, it also contributes to creating a pleasant acoustic environment in reception, lobby or waiting areas.

High sound performance, energy saving

The speaker's 90 dB sensitivity means that only a small input power level is required, APlus A-B04 ceiling speaker can produce sound loud enough to cover the space effectively. This is a very important factor in systems using many speakers, because it helps reduce the load on the central amplifier, prolong the life of the equipment and optimize investment costs.

With high sensitivity, the speaker can produce clear and even sound without having to set the amplifier at high power level, thereby saving energy during operation. This is especially beneficial in environments such as hospitals, schools, and shopping centers, where the sound system must operate continuously for hours every day.

Practical application of APlus A-B04 announcement speaker
