OBT 107 ceiling speaker is one of the top choices in the segment of high-quality low-cost ceiling speakers, thanks to its ability to produce consistent sound, sophisticated design and stable performance. Widely used in homes, offices, shops and public buildings, this product brings outstanding value in both listening experience and aesthetic factors.
OBT 107 has a classic round design, with a diameter of 185mm and a depth of only 105mm, making it easy to install on plasterboard or wooden ceilings. Weighing only 0.65kg, the construction does not require much labor and does not affect the ceiling structure. The speaker body is made of heat-resistant ABS plastic, allowing stable operation in environments with high humidity or changing temperatures.
The speaker face is covered by a rust-free, powder-coated aluminum mesh, ensuring durability and aesthetics. The clamp-type mounting mechanism helps to firmly fix without the need for a cumbersome hanging frame, saving installation time. With a 160mm hole size, the OBT 107 speaker is easily compatible with ceilings with current construction standards.
The OBT 107 speaker delivers stable sound performance thanks to a frequency response range of 100Hz - 15kHz, enough to clearly reproduce important sound ranges such as voices and background music. Sensitivity reaches 90 ± 2dB, helping the sound spread evenly throughout the space without the need for a large power amplifier. The rated power level of 3W or 6W makes it easy for users to set up to suit each area.
With a 70V/100V audio transmission system, the product can be easily integrated into a multi-point public address or background music system. The speaker is designed to reproduce sound at a stable acoustic pressure level, reducing distortion, anti-howling and not causing ear-piercing when playing at high volume continuously. Thanks to the closed resonance structure, the sound is not reflected back to the ceiling, reducing sound loss.
Using OBT 107 brings many practical benefits, especially in spaces that require aesthetics and stable sound performance. With the ceiling installation mechanism, the product helps save space and keep the space neat and modern. OBT 107 is widely used in offices, cafes, shopping malls, meeting rooms or restaurants, where soft, quiet but still clear and pleasant sound is required.
The 70V/100V high voltage system allows multiple speakers to be connected on the same line, suitable for zoning sound models. At the same time, with low power and high sensitivity, the speaker consumes very little power, contributing to saving long-term operating costs. This is also a plus for large-scale installation projects such as office buildings, hotels or chain stores.
To properly install the OBT 107 speaker, you need to drill a hole with a diameter of 160mm and make sure the ceiling is thick enough to clamp the speaker. After drilling, connect the signal wire from the amplifier (at 70V or 100V) to the two poles of the speaker, then gently put the speaker into position, using the ceiling clamp-mounting mechanism to hold it tight. Finally, check the connection and try to play the sound.
In particular, if installed in a high humidity environment such as a covered outdoor corridor or near a kitchen, ensure that the wiring is shielded and waterproof. Using the correct voltage and polarity will help prolong the life of the speaker and ensure performance.
Compared to products such as Bosch LBC 3090/01 or JBL Control 24CT, the OBT 107 speaker is significantly cheaper but still ensures basic specifications such as frequency range, sensitivity and RMS power. While JBL Control 24CT costs over 1 million VND, OBT 107 is only about 300.000 VND, suitable for large-scale projects that need to optimize the budget.
In terms of design, the OBT 107 still maintains a high level of perfection with uniform colors, less dust and no discoloration over time. In addition, the strength of the OBT 107 is also easy to install, easy to replace and maintain - something that many construction engineers highly appreciate. With a power level of 6W and a sensitivity of 90dB, this product can play background music or clear voice in a space of 15 - 30m² per speaker, while still saving energy and wires than low impedance speakers.
According to feedback from installation units, OBT 107 is widely used in school, apartment, and shopping center projects thanks to its low price, ease of construction, and few technical errors. Mr. Huy - a sound engineer in Ho Chi Minh City said: "We have installed more than 300 OBT 107 speakers for the background music system of a supermarket chain.
The sound is even, not too harsh and especially very stable over a long period of time." A personal user also shared: "I installed it myself for a small cafe, at first I was a bit worried because of the cheap price, but after more than 6 months, the speaker still plays evenly, sounds smooth and has no distortion." Overall, the product received positive reviews in both technical and cost factors.
The OBT 107 loudspeakers work effectively in spaces ranging from 15 to 30m² per speaker, depending on ceiling height and required volume level. For larger spaces, you should arrange additional speakers to ensure the sound is evenly distributed and there are no dead spots.
Ceiling speakers OBT 107 uses 70V/100V input voltage, so you need to use a dedicated amplifier for high-impedance speaker systems. Do not connect directly to a regular 8Ω amplifier because it may cause the speaker to burn or damage the amplifier.
Yes. The OBT 107 is specifically designed for Public Address (PA) and Background Music Systems, making it ideal for both continuous background music and microphone announcements thanks to its wide frequency range and clear sound.
If installed properly and using the right 70V/100V amplifier, the OBT 107 speaker can last from 5 to 10 years, thanks to the heat-resistant ABS plastic material and internal components that are optimally designed for continuous operating environments.
