OBT 106 ceiling speaker is a dedicated audio device designed to be installed recessed into the ceiling, providing a smooth and aesthetic music listening experience for living or working spaces.
The product has a compact design with high-quality polypropylene material, helping to increase durability, moisture resistance and is suitable for many different environments such as offices, restaurants, cafes or residential areas.
The integration of 70/100V transmission technology makes the OBT 106 easy to combine in multi-speaker sound systems without using too many complicated wires. In this article, we will analyze in depth the outstanding factors of the OBT 106 such as sound quality, performance, design structure, application ability, installation and actual feedback from users.
The OBT 106 ceiling speaker is designed in a minimalist circular shape, with an overall diameter of only 120mm and a height of 80mm, allowing for compact installation in thin plasterboard ceilings or standard ceiling structures. Made of high-quality white Polypropylene plastic, the speaker is both light and moisture-resistant, easy to clean and resistant to rust like some metal speakers.
The spring clip installation method helps to fix the speaker quickly with just a press, without the need for screws or specialized accessories, saving time and construction costs. In addition, the sharp design and thin speaker border help the OBT 106 become almost "invisible" when installed, keeping the ceiling clean and seamless - a very popular element in modern interior design.
The OBT 106 is equipped with a full-range speaker capable of reproducing sound in the frequency range from 100Hz to 15kHz, helping to respond to both speech and light background music. With a sensitivity of up to 92 ± 2dB, the product can produce high volume from low power, suitable for moderate-sized spaces such as offices of 20-40m².
360-degree uniform sound diffusion technology allows sound to spread evenly throughout the space without echo or distortion. In fact, when installed in small meeting rooms or showrooms, listeners can clearly feel each broadcast without having to increase the volume too much, thereby avoiding ear fatigue. OBT 106 is also especially suitable for background music applications in restaurants, spas, and cafes thanks to its tight bass and bright treble.
The OBT 106 speaker uses 70V or 100V input voltage, which is the standard in public address systems (PA systems), helping to minimize signal loss when running long cables, and allowing multiple speakers to be connected on the same signal line. Rated power of 5/10W and maximum power of up to 10/20W allows the speaker to operate stably for a long time without distortion or overheating.
This helps the OBT 106 save energy while ensuring optimal sound transmission performance. With dedicated amplifiers ranging from 60–120W, users can install up to 6–10 OBT 106 speakers at the same time while still maintaining stable sound quality throughout the system. This is the strength that makes the OBT 106 an ideal choice for commercial projects that require evenly distributed, light and clear sound.
Wide compatibility and compact design make the OBT 106 ceiling speaker flexible to be applied in many different types of spaces. In the office area, the speaker is used for announcement systems and light background music to create a comfortable working environment.
In cafes, restaurants, hotels or spas, OBT 106 helps spread gentle sound, contributing to improving the customer experience. The product is also commonly used in public address systems in schools, supermarkets, hospitals, etc. thanks to its clear pronunciation and frequency response for both voice and music.
With its moisture-resistant ability, OBT 106 can also be installed in bathrooms, kitchens or hallways – places with high humidity and susceptible to corrosion.
Compared to many popular ceiling speakers on the market, OBT 106 has many outstanding advantages in both design and performance. While many cheap speakers only support a maximum power of 10W and a frequency range of 150Hz, OBT 106 provides a peak power of up to 20W, with a frequency response down to 100Hz - helping to express the bass more clearly.
The higher sensitivity than the market average (92dB compared to the common 88–90dB) allows the speaker to produce a louder volume with the same input power level, saving more power. In addition, the moisture-proof polypropylene plastic material of the OBT 106 is much superior to iron-shell speakers that are prone to oxidation after a long time of use.
The final strength is the clamping method – fast, strong and does not require complicated tools, making OBT 106 popular in fast construction projects such as cafes, showrooms or renovated offices.
Installing the OBT 106 ceiling speaker is relatively simple and can be done by non-professional users, as long as the correct technique is followed. First, you need to determine the appropriate ceiling position so that the sound spreads evenly and is not blocked. Then, use a drill to cut a 100mm diameter hole in the plasterboard or light wooden ceiling.
The 70V/100V signal wire from the amplifier will be connected directly to the speaker via the rear terminal, ensuring correct polarity and secure contact. Next, you just need to squeeze the spring clip and push the speaker into the hole - the clip will pop out to hold the speaker firmly to the ceiling. After turning on the power, check the audio signal again and adjust if necessary.
Thanks to its smart clamp design and compact size, OBT 106 can be installed in series in a very short time, suitable for projects requiring quick construction.
To keep the OBT 106 ceiling speaker working effectively for a long time, users should perform periodic inspection and cleaning every 6 months. The speaker surface can be gently wiped with a dry or slightly damp cloth - absolutely do not use strong detergents because they can damage the speaker shell.
In case of installation in dusty environment or near the kitchen, use a mini vacuum cleaner to clean the heat sink and speaker protection mesh. In addition, periodically checking the signal wire, connection point and power source will help prevent short circuit or sound degradation.
The speakers should also be kept away from heat sources such as water heaters, high-power ceiling lights or gas stoves – to ensure the durability of the plastic material and the sound quality are not affected by temperature.
Many users rate the OBT 106 ceiling speaker as a “small but powerful” product, because despite its small size, the sound it produces is still clear, enough for a space of 20-40m². Some customers who are cafe and spa owners appreciate the ability to evenly disperse sound and bright treble – making the background music pleasant to listen to, without being harsh.
In addition, the ability to self-install is also a big plus, especially for those who need to equip themselves with a sound system for their office or home. In addition, the product's durability also receives positive feedback from users, when many customers share that the speaker still works well after more than 2 years of use in high humidity conditions.
Although it has a higher price than some popular models, in terms of durability, sound quality and aesthetic design, most people consider the OBT 106 to be a "worth the money" choice.
The OBT 106 ceiling speaker is specially designed for use in small and medium sized enclosed spaces, from 15m² to about 40m². With a rated power of 5/10W and a high sensitivity of 92dB, the product can produce clear sound even when only 1-2 units are used in a standard space. Typical applications include: offices, meeting rooms, cafe sound, spa, showroom, reception hall, massage room, WC area or apartment corridors, shopping malls.
OBT 106 uses a 70V/100V high voltage broadcasting system, so it requires an amplifier compatible with this line, often called a distribution amplifier or a dedicated amplifier for the PA (Public Address) system. Suitable amplifiers usually have a capacity of 60W or more, such as TOA A-2030, OBT-6060A or equivalent lines. The selection karaoke amplifier Correct voltage and power help the system operate durably, while optimizing sound transmission efficiency for multiple speakers at the same time.
Despite its compact size, the OBT 106 speaker is still considered to have the ability to reproduce relatively full-range sound, enough to play background music in quiet environments such as spas, cafes, restaurants or supermarkets. The frequency range from 100Hz to 15kHz allows the speaker to clearly express musical instruments, soft vocals and simple sound effects. However, if you require playing vibrant music with deep bass or high volume, the OBT 106 may not be enough to satisfy like speakers with larger bass.
The answer is absolutely yes. One of the outstanding advantages of the OBT 106 is the mechanical design of the ceiling clamp which is very user-friendly for non-professionals. You just need a hand drill, saw a hole in the ceiling with a diameter of 100mm (you can use a plaster cutter or a specialized drill bit), then connect the audio wire according to the correct polarity (+/–) and push the speaker into the correct hole. The clamp will automatically pop out and hold the speaker firmly to the ceiling.
