OBT CS10 ceiling speaker is a professional audio solution designed to be subtly integrated into the ceiling, providing a vivid music listening experience and uniform sound coverage throughout the space. With a compact design, minimalist design but outstanding performance, this product is becoming a popular choice in projects such as offices, restaurants, cafes or shopping centers.
The OBT CS10 has a circular design, with a speaker face diameter of only 175mm and a height of 60mm, allowing for subtle ceiling mounting without affecting the interior space. The speaker body is made of durable ABS plastic, resistant to heat and humidity, helping the product operate stably in harsh environments such as kitchens, hallways or covered semi-outdoor areas.
Weighing only 0,36kg is also an advantage to help reduce ceiling load and make construction faster. The design uses elastic spring clamps to make fixing the speaker to the ceiling easy, without the need for cumbersome mounting frames or deep drilling. In short, the OBT CS10 ceiling speaker is structured to serve the deployment of fast, neat, beautiful and effective construction.
The product supports two rated power levels of 5W and 10W depending on the wiring method and actual usage needs. This is a prominent feature that helps users flexibly adjust the volume level according to each area. With a maximum power level of 20W, the speaker still ensures stability when operating continuously for a long time without overheating.
The OBT CS10 is compatible with systems using 70V or 100V transmission voltages, the common standard in public address systems. Supporting these two voltage levels allows multiple loudspeakers to be connected on the same line without significant power loss – useful when designing sound systems for buildings or chain stores.
With an operating frequency range of 100Hz to 15kHz, the OBT CS10 ceiling speaker reproduces sound with enough detail to convey both voice and background music. This frequency range is suitable for announcements, soft music or quiet spaces where sound is easy to listen to and does not cause ear fatigue.
The speaker's sensitivity reaches 92 ± 2dB - an ideal parameter for small-capacity speakers, helping to optimize sound output without consuming much energy from the amplifier.
With a 5.25-inch diameter speaker membrane, the OBT CS10 is capable of creating a wide sound field, spreading evenly in a space of 20-40m² depending on the speaker arrangement. Thanks to the sealed anti-interference design and selected materials, the speaker also minimizes distortion or crackling when playing voices at high volumes.
The OBT CS10 ceiling speaker is optimized for projects requiring high aesthetics and limited space. With a spring clamp ceiling mount design, users can quickly install it directly into plasterboard or aluminum ceilings without the need for specialized tools.
In particular, due to its light weight and simple structure, mass installation of OBT CS10 in multi-zone sound systems such as restaurants, resorts, offices or shopping centers will save significant construction time.
Not only does it work well in quiet environments, this product is also used in areas with medium noise levels such as cafes and mini supermarkets, thanks to its clarity and ability to amplify sound evenly.
Compared to other ceiling speaker lines on the market such as JBL Control 16C/T, TOA PC-658R or Bose FreeSpace DS16, OBT CS10 has clear advantages in compact design, quick construction and affordable price.
While higher-end products are geared towards deep music reproduction, the OBT CS10 is optimized for practical applications in background music and announcement systems – where clarity, low cost and high durability are required.
Although it does not have a wide frequency range like hi-end speakers, the CS100's 15Hz - 10kHz response range fully meets the common requirements in civil works. At the same time, the OBT CS10 is easier to match because it is compatible with the 70/100V voltage standard without the need for a separate converter, which many international speakers require.
Practical use shows that OBT CS10 operates stably for a long time, providing clear sound, separate voices and no distortion even at high volume levels.
The speaker's bass is moderate, mainly to create a warm background, while the midrange and treble are clearly expressed, very suitable for spaces such as meeting rooms, classrooms or places that need to convey information through speakers. High sensitivity helps reduce the load on the central amplifier, allowing the system to operate stably with multiple speakers on one line.
Technicians also appreciate the speaker's ability to resist moisture and isolate electromagnetic interference, ensuring it is not affected when installed near light sources or high-power electrical equipment.
Yes. OBT CS10 is a speaker line designed specifically for public address system and background music. With a selectable power of 5W/10W and high sensitivity (92 ± 2dB), the speaker fully meets the needs of use in meeting rooms, offices or classrooms while still ensuring clear sound, without glare or loss of sound.
Yes, but it is more suitable for light music, background music than listening to high quality music. Because the speaker has a frequency range of 100Hz - 15kHz, the sound is biased towards dialogue and midrange, very suitable for playing instrumental music, light music, ballads or BGM in cafe sound system, spa, store. If you need high quality music speakers, you should choose full-range speakers or wall-mounted speakers that support deeper frequency ranges.
This depends on the power and impedance of the amplifier. With a system using 100V voltage, if each OBT CS10 speaker uses 10W power, then one ampli 240W can pull about 20-24 speakers. However, to ensure performance and durability, you should calculate according to the actual power used and leave about 15-20% of the amplifier's power left.
Is not. Ceiling speakers OBT CS10 is designed with a ceiling spring clamp, so you only need to drill the correct size of the speaker face (175mm). No need for additional hanging frames or complicated brackets. Installation is quick and does not affect the current ceiling structure. This is a great advantage of the OBT ceiling speaker line.
