OBT 816 ceiling speaker is a prominent product of the OBT brand - a unit specializing in providing high-end public audio and architectural audio equipment. This is one of the most popular ceiling speaker models today thanks to its compact design, clear sound and good integration in many different types of spaces.
The OBT 816 ceiling speaker is built on a streamlined design philosophy, integrating a 6.5-inch woofer to reproduce deep bass and a 1-inch tweeter to deliver clear highs, creating a 2-way driver system structure that is optimal for enclosed spaces.
The device operates on a 70V/100V voltage signal source, suitable for parallel distribution sound systems, saving wires and simplifying connections. The speaker's nominal power is 5W, reaching a maximum of 10W, suitable for background music and broadcasting needs in spaces from 15 to 30 square meters.
With a frequency response ranging from 100Hz - 15kHz and a sensitivity of 90 ± 2dB, the speaker ensures clear sound reproduction without distortion even when operating at high power levels continuously. The speaker has a speaker face size of 200 x 67 mm, weighs only 0.75 kg, uses a convenient spring clamp mounting method, does not require fixing screws, helping users to easily install quickly while still ensuring safety and high aesthetics.
OBT 816 is developed with a true acoustic orientation, the ability to reproduce balanced sound between three frequency bands, especially outstanding in the ability to play voice and background music clearly. Thanks to the 2-way speaker structure, the device can separate the mid-bass and high-range into two separate speaker membranes, helping to optimize the direction of sound and reduce distortion.
The high sensitivity of 90dB ±2dB allows the speaker to easily achieve high volume with low power, especially useful in systems using multiple speakers. The operating frequency of 100Hz to 15kHz ensures full coverage for soft music, background music or voice from the microphone.
This makes the OBT 816 not only a music speaker but also an ideal solution for public address systems (PA systems) in public buildings. For spaces that require sound that is not too bright or harsh such as offices, shopping malls or meeting rooms, the gentle and clear sound quality of the OBT 816 is completely suitable.
One of the outstanding advantages that makes OBT 816 a popular product is its ease of installation and suitability for all ceiling architectures. The speaker is designed to be mounted directly to the ceiling via the spring clamp method, just drill a 170mm hole in the ceiling and gently press the speaker in to complete, no screws required, no damage to the ceiling structure.
With a compact round speaker face, white electrostatic paint, the product easily blends into any interior space without causing a rough or obvious feeling. This is a big plus for projects with high aesthetic requirements such as hotels, restaurants, showrooms or luxury apartments.
In addition, with a closed back design, the speaker is also more resistant to dust and moisture, ensuring durability in conditions where the ceiling is often exposed to moisture or high temperatures. The heat-resistant ABS plastic material structure also helps the speaker to be more durable when operating continuously for a long time.
The OBT 816 speaker is considered extremely flexible in deploying sound systems, from small scales such as individual apartments to public systems such as buildings, schools, offices or shopping centers.
In the home, the OBT 816 is often used to create relaxing background sound in the living room, hallway, dining room or bedroom, helping to enhance the living experience and entertainment facilities. With its gentle sound characteristics that do not cause ear fatigue, the speaker is also suitable for continuous background music in cafes, spas, beauty salons or showrooms.
In educational institutions and hospitals, the device is integrated into the public address system thanks to its clear, noise-free voice quality, ensuring accurate information transmission. With its light weight and small capacity, the OBT 816 is also the optimal choice when it is necessary to install dozens of synchronized devices in a large space without putting pressure on the power system.
Compared to the popular ceiling speaker lines currently on the market, OBT 816 is superior in both design and performance. While many low-cost models only support 3W - 6W power and single driver structure, OBT 816 uses a 2-way driver system, allowing better sound separation, creating clarity in every small detail.
The OBT 90's sensitivity of 2dB ±816dB helps the speaker produce louder sound with the same power compared to other speakers, saving electricity and reducing system investment costs. In addition, many other products use thin plastic shells or do not have dust shields, which are easily oxidized or deformed over time.
Meanwhile, OBT 816 uses ABS plastic material combined with electrostatic painted steel mesh, which is both light and durable, moisture-proof and heat-resistant, ensuring superior longevity in hot and humid climates like Vietnam. In addition, the spring clamp installation method does not require drilling screws or bolts, helping to shorten construction time from 15 minutes to less than 5 minutes, reducing installation labor costs for large-scale projects.
After experiencing the OBT 816, users gave positive reviews about both the sound quality and the convenience of use. Outstanding feedback shows that the sound from the speaker is very clear, without noise, especially when playing soft music or broadcasting with a microphone, suitable for both quiet spaces like offices and crowded spaces like coffee shops.
Easy self-installation without calling a professional helps users save a significant amount of money. Some customers also emphasize that the compact and beautiful speaker design makes the product almost disappear in space, not causing confusion like conventional hanging speakers.
Although some argue that the price is higher than some unknown Chinese models, most buyers agree that the build quality, durability, and sound of the OBT 816 are well worth the investment.
Ceiling speakers OBT 816 is designed to serve well for spaces from 15m² to 30m² with only one speaker, thanks to a maximum power of 10W and a sensitivity of 90 ±2dB. In case of a larger space or many areas that need even sound coverage, you can arrange 2-4 speakers in combination according to an even distribution diagram. Choosing the right number of speakers according to the area will help limit the phenomenon of "dead sound spots", while optimizing the stereo effect or broadcasting across the entire area if it is necessary to connect a zoning sound system (zoning PA system).
The OBT 816 speaker can be used to play high-quality background music thanks to its 2-way speaker structure, allowing full reproduction of the frequency range from 100Hz to 15kHz. This makes the bass deep enough to listen to light or acoustic music, while the mid and treble are clear enough so that the vocals are not drowned or distorted. However, with a small power level, the speaker is not suitable for high-intensity audio entertainment purposes such as karaoke or DJ, but is more suitable for spaces that require ambiance such as cafe sound system, spa, office, or showroom.
OBT 816 uses 70V/100V input, which means it operates on a high voltage distributed audio system, so it needs to be used with karaoke amplifier for PA or background music systems that support 70V/100V output ports. Conventional amplifiers for low impedance speakers (8 Ohm) will not be compatible without a transformer adapter. Therefore, to ensure optimal performance and system safety, the OBT 816 should be paired with genuine PA amplifiers such as OBT, TOA or Bosch that have integrated high-voltage output ports.
One of the outstanding advantages of OBT 816 is the ability to easily self-install thanks to the spring clip mechanism and the thin and light speaker face design. If you have already drilled a hole in the ceiling with the correct size of 170mm, installing the speaker only requires a few simple steps: attach the speaker wire with the correct polarity, press the speaker into the hole and make sure the spring clip opens to hold the speaker face firmly. However, for systems with multiple speakers connected in parallel or with audio zones, you should carefully refer to the wiring diagram or ask a technician to set up a suitable amplifier source to avoid volume differences between areas.
