Detailed review of Bosch LHM 0626/00 speaker configuration

Before making a decision on a professional ceiling sound system, it is essential to carefully evaluate the configuration and actual performance of the equipment. With Bosch LHM 0626/00 . ceiling speaker, not only stopping at aesthetic design but also a thorough investment in technology, optimizing for modern announcement sound systems and background music.

Compact design, highly aesthetic and suitable for many types of ceilings

Bosch LHM 0626/00 ceiling speaker has a compact recessed ceiling design with an overall diameter of 199 mm, integrated with a white electrostatic painted metal mesh RAL 9010 - a standard color code commonly used in modern interior architecture.

Thanks to its round shape and elegant white coating, the speaker easily blends in with plasterboard, aluminum or industrial wood ceiling designs, without affecting the overall aesthetics of the space.

Not only is it aesthetically pleasing, it is also optimized for professional installation. The 3-point screw ceiling mounting mechanism (instead of the usual spring clamp) ensures stability and limits vibrations after long-term use. The 77 mm installation depth is ideal for projects with thin ceilings or limited space above the ceiling.

In addition, the 900g weight combined with the 150g magnet is just enough to ensure stable magnetic force while remaining absolutely safe when hanging from the ceiling - which is very important when installing in large projects.

Multi-level power configuration – flexible for each area of ​​use

A prominent technical advantage of this model is the integrated transformer that allows power selection at the following levels: 6 / 3 / 1,5 / 0,75 W. This is a very important factor in a distributed audio system using 100V voltage.

Users or technicians can customize the power of each speaker based on room size, intended use (background music, announcements, emergency information), or system configuration by zone.

For example, in an office hallway, only 0,75W is needed to play soft music, while in a waiting room or large meeting room, it can be increased to 6W to ensure the volume is loud and clear enough. This ability to customize power not only helps the system save energy, but also optimizes the cost of deploying amplifiers and cables for each specific project.

High sound pressure level ensures clarity in a wide range of environmental conditions

In terms of audio performance, Bosch LHM 0626/00 capable of emitting sound with SPL (Sound Pressure Level) reaching 99 dB at 6W – 1kHz, and 104 dB at 6W – 4kHz, showing clear sound reproduction in both mid and high frequencies. High SPL means sound can travel further in large spaces or environments with background noise.

At a low power of 1W, the speaker still maintains sound clarity at 91 dB (1kHz) and 96 dB (4kHz), ideal for playing soft background music or for use in areas where high volume is not required. In particular, the high SPL at 4kHz helps to clearly reproduce consonants in the voice - a key factor in high-precision announcement systems.

Wide frequency range, good reproduction of both background music and voice

The speaker has an operating frequency range of 70 Hz to 18 kHz (-10 dB), wide enough to convey both clear speech and deep music. Bass down to 70 Hz allows for light bass in background music, while highs open up to 18 kHz for bright, clear sound that is comfortable for long listening sessions.

In practical implementation, wide frequency range helps Bosch LHM 0626/00 . ceiling speaker Not only can it be used for PA (Public Address) systems, but it is also effective in background sound systems at cafes, spas, bookstores, libraries, hotels or training centers.

Wide standard negative coverage angle – optimizes installation density

Sound coverage is a very important factor in ceiling sound systems. With a coverage angle of 160° at 1kHz and 55° at 4kHz (standard -6 dB), Bosch speakers ensure sound is evenly distributed throughout the space, minimizing dead spots or weak sound areas.

Secure screw connection, easy to maintain and mass installation

Bosch LHM 0626/00 ceiling speaker Using 2-pole screw connectors, allowing the wire to be firmly fixed, avoiding loose wires after long-term use. This type of connection also supports quick mass construction, especially suitable for projects deploying many speaker points at the same time such as hotels, resorts, high-rise apartments or general hospitals.

Using screw terminals instead of jacks also makes inspection and maintenance easier when the speaker needs to be removed for repair or routine inspection.
