Bosch LBC 3099/41 Ceiling Speaker

Bosch LBC 3099/41 . Ceiling Speaker is a specialized broadcasting device designed to be integrated into public address systems (PA systems), providing clear, evenly distributed sound in large spaces such as offices, shopping malls, hospital corridors or waiting rooms.

Thanks to its broadband audio technology, combined with a compact design and aesthetic ceiling installation capabilities, this product becomes the ideal choice for projects requiring professionalism, high durability and outstanding audio performance.

Engineering design and material structure – Acoustic optimization and durability

Bosch LBC 3099/41 is built with a 203,2 mm (8 inch) diameter speaker, providing better low frequency sound reproduction, while helping the sound spread evenly throughout the space.

The speaker face and frame are made of fireproof ABS plastic, coated with white paint code RAL 9010, ensuring safety in public environments while increasing aesthetics when mounted on plasterboard or suspended ceilings. The overall dimensions of the speaker are 265 mm in diameter and 89 mm in depth - an ideal ratio for neat installation without disrupting the space design.

This is a line of speakers designed in flush-mount style (mounted flat on the ceiling), helping to increase acoustic resonance while limiting sound energy dissipation in open environments.

Audio Performance – Clear, well-distributed sound

The product has an optional rated power of 6/12/24W, operates on a standard voltage of 100V and provides a maximum SPL of up to 107 dB at 4 kHz – enough to ensure information is transmitted clearly even in areas with high background noise.

With an effective frequency response of 60 Hz to 18 kHz (-10 dB), the Bosch LBC 3099/41 delivers both soft bass and clear mid-high tones – ideal for public address systems, background music and speech-focused applications.

The ability to maintain frequency stability in a variety of installation conditions is one of the factors that helps the product achieve broadcast-grade standards in the ceiling speaker segment.

Sound coverage and directivity – Even sound dispersion, no missing listening area

The loudspeaker is designed with a wide opening angle of 160° at 1 kHz and 60° at 4 kHz (-6 dB level), which means the sound is distributed extremely wide in the speech frequency range – an important factor in public environments or open spaces where listeners may move around constantly.

The stability in the directivity index helps reduce the phenomenon of uneven sound reflection and limit dead zones. This is a big advantage compared to ceiling speakers with coverage angles of less than 100°, which often cause uneven sound between areas in the space.

Installation – Easy, space and time saving

A big plus of the Bosch LBC 3099/41 is the ability to install quickly thanks to the ceiling mounting mechanism with a standard mounting diameter of 210 mm. The speaker weighs only 1,8 kg so it can be easily fixed with screws, without the need for a complex load-bearing structure.

The 3-pole screw-in connector ensures a secure wire connection, minimizing flickering caused by oxidation or vibration. The flush-mount design minimizes the distance from the speaker to the ceiling surface, optimizing the sound phase and avoiding the loss of sound energy behind the ceiling – a common problem with surface-mount speakers.

Durability and practical application – Stable operation in all environments

The Bosch LBC 3099/41 is capable of operating well in harsh environmental conditions thanks to its moisture-proof, dust-proof design and the use of fire-resistant materials. This makes the product especially suitable for places with high humidity, high traffic, or buildings requiring strict safety standards such as hospitals, schools, train stations and industrial areas.

In addition, the 417 ohm rated impedance makes it easy to pair in series sound systems on 100V lines - which is a common standard in modern public address systems.

Compare Bosch LBC 3099/41 speakers with similar products

When comparing the Bosch LBC 3099/41 to its competitors in the same segment as the Crown CM Series or the Yamaha VXC Series, the noticeable difference lies in the maximum SPL and frequency range. While the Crown has the advantage in industrial design, the Bosch excels in sound uniformity and stable operation in harsh environments.

Compared to Yamaha, Bosch LBC 3099/41 has a softer price but still ensures clear sound and solid structure. If your requirements are more about durability, flexible system integration and ease of installation, Bosch LBC 3099/41 is definitely a more worthy choice than speakers in the same price range.

Frequently asked questions about Bosch LBC 3099/41 Ceiling Speakers

Is Bosch LBC 3099/41 speaker suitable for offices and shopping malls?

Yes. With its wide 160° coverage, compact design and clear sound, the Bosch LBC 3099/41 loudspeaker is ideal for spaces such as notification sound, hall sound, large halls or public corridors. The recessed design helps ensure high aesthetics for modern interiors.

Can Bosch LBC 3099/41 speakers be used in 100V systems?

Yes. The product is designed to be fully compatible with cafe sound system 100V, 417 ohm impedance and supports 6W, 12W or 24W power options. This is the optimal choice for projects that require deploying multiple speakers simultaneously on the same line.

Is it easy to install Bosch LBC 3099/41 speakers?

It's easy. Just cut a 210mm diameter hole in the ceiling, attach the speaker with a 3-pole screw and connect the speaker wire. With its light weight and depth of only 89mm, it fits into a wide range of ceilings without the need for additional reinforcement.

Are the speakers moisture resistant and suitable for high humidity environments?

Yes. The speaker is made of fireproof ABS plastic, which is resistant to moisture and dust, so it can operate stably in high humidity environments such as train stations, hospitals or covered outdoor areas. However, direct contact with rain should be avoided to increase durability.
