OBT 108 ceiling speakerThe OBT 108 ceiling speaker is an optimal choice for spaces that require high-quality sound combined with a sophisticated and space-saving design. This product is especially suitable for installation in offices, showrooms, cafes, restaurants, hospitals or public areas thanks to its ability to reproduce clear, faithful and even sound throughout the space.
The OBT 108 ceiling speaker is designed with a traditional round shape, using high-quality white polypropylene plastic that is both lightweight and has good moisture and corrosion resistance in tropical environments.
This design not only ensures high durability over a long period of time but also creates synchronization and harmony with many different types of ceilings such as plasterboard ceilings, concrete ceilings or aluminum ceilings. OBT 108 uses a ceiling mounting mechanism using the clamp method, making construction easy and quick, without affecting the ceiling structure.
The standard 180mm cutout and 240mm overall speaker diameter allow for neat integration into most ceilings without disrupting the overall aesthetic. Weighing just 0.72kg, this product is ideal for spaces that require a minimalist, modern and clean interior design.
Although the OBT 108 has a modest capacity (5/10W rated, 10/20W maximum), it still produces clear, balanced sound performance with even coverage thanks to a sensitivity of up to 92 ± 2dB. The frequency response from 100Hz to 15kHz helps the speaker reproduce both voice and background sounds well, especially in applications such as soft music, announcements or internal PA systems.
With a standard impedance of 8 ohms and the ability to operate at 70V/100V voltage, the speaker is easily compatible with most central audio systems or zone controls today. Thanks to its optimized acoustic structure, the speaker produces clear sound at high frequencies and is not distorted when operating at the highest power level. This is an ideal choice for spaces from 15-30m², where the sound is needed to be even, pleasant, and not cause ear fatigue when listening for a long time.
The OBT 108 speaker is designed to optimize energy savings in distributed audio systems by operating at a high voltage of 70V/100V - a common industry standard in large projects. With low power consumption, from only 5W to a maximum of 20W, the product not only helps save operating costs but also ensures stable operation over a long period of time.
This is especially useful for systems that must operate continuously for many hours, such as announcement systems in shopping malls, schools, or office buildings. In addition, thanks to the simple circuit system, low heat generation and dust/moisture resistant design, the OBT 108 loudspeaker rarely has technical problems, significantly reducing maintenance costs throughout its life cycle.
One of the biggest advantages of the OBT 108 is its quick installation without the need for a professional technician. The product uses a ceiling spring clamp method, allowing users to simply drill a 180 mm diameter hole, insert the speaker and secure it with the available spring mount.
This design does not require screws or auxiliary brackets, shortening construction time and significantly reducing labor costs. In addition, the speaker is also equipped with connecting wires with extremely clear symbols, supporting the installer to easily connect the positive and negative poles correctly, avoiding the phenomenon of reverse phase distortion.
Thanks to its light weight, sturdy construction and overall diameter of 240 mm, the OBT 108 can be installed on ceilings such as plasterboard, wooden ceilings or lightweight concrete without affecting the adhesion of the ceiling system.
Compared to products in the same segment such as DB TS 301 or TOA PC-658R, the OBT 108 ceiling speaker has some clear advantages in design and performance. Specifically, while DB TS 301 only has a capacity of 5W and a sensitivity of 89dB, OBT 108 reaches a rated 10W and a sensitivity of 92dB - meaning the sound is stronger and clearer under the same operating conditions.
The polypropylene plastic material also helps the speaker to be more moisture and heat resistant, especially suitable for tropical monsoon climates like in Vietnam. In addition, the OBT 108 is also easier to install than models that require a separate mounting frame.
In terms of cost, OBT 108 is often more reasonably priced than TOA with the same configuration, helping to save initial investment costs while still ensuring long-term efficiency. It is the balance between performance, durability and price that makes OBT 108 the most popular product in the popular ceiling speaker segment.
Using OBT 108 ceiling speakers brings many practical benefits in both living and commercial environments. First of all, the ceiling design helps save installation space, while creating harmony for the interior, especially in areas that require high aesthetics such as showrooms, restaurants or reception rooms.
In addition, the sound emitted from the ceiling helps to cover the sound field evenly, avoiding negative reflections like when using wall-mounted or desktop speakers. Flexibility in connection and installation helps users easily expand the system to each area without changing the ceiling structure.
In particular, with high durability and low maintenance costs, OBT 108 helps save significantly on long-term operating budgets, making it a worthy investment solution for large construction projects or chain stores and offices that need to synchronize sound systems.
Most users who have used the OBT 108 ceiling speaker have positive feedback on the sound quality and durability of the product. Many customers from companies that design and construct PA systems said that the speaker has the ability to reproduce mid and high tones very clearly, especially suitable for broadcasting announcements, background music or instrumental music in service spaces.
Some individual users also shared that self-installation of the speaker is very easy, without hiring a professional team, thanks to the convenient clamp design and detailed instructions from the supplier. In terms of design, the speaker is highly appreciated for its compactness and white color that easily blends with the interior.
However, some feedback also said that OBT 108 is not suitable for use in large spaces or playing vibrant music with deep bass. However, with basic to average needs, most users are satisfied and willing to recommend this product to friends and partners.
The OBT 108 speaker works best in spaces from 15 to 30m², depending on ceiling height and intended use. With high sensitivity and a maximum power of 20W, the product is capable of evenly covering sound in spaces such as meeting rooms, cafe sound, office, hallway or lobby.
Yes. Ceiling speakers The OBT 108 is designed to operate in a 70V/100V high impedance sound system, so it should be paired with a dedicated amplifier for a distributed system (public address), such as the TOA, OBT or DB amplifiers. Do not connect directly to low impedance household amplifiers to avoid sound distortion or speaker burnout.
Not difficult at all. OBT 108 uses the ceiling clamp mounting method, just drill the right size hole (Ø180mm) and attach the speaker with a spring mount. With basic tools and a little care, users can completely install it at home without hiring a professional. However, if you need to install a system of many synchronized speakers, you should ask a professional sound engineering unit to advise on the connection diagram.
The OBT 108 speaker has a high-quality polypropylene plastic shell, which is moisture-proof, anti-oxidizing and can withstand the humid air conditions commonly found in buildings in Vietnam. However, to ensure long-term durability, you should still avoid installing it directly in areas exposed to water such as bathrooms, open kitchens or uncovered outdoor areas.
