BOSCH LHM0606/00 Ceiling Mount Speaker 6W LHM-10MGE LHM-30MGE LHM-50MGE, LHP-60CGE Marine PRA-EOL PRA-EOB

A professional Public Address (PA) and Voice Alarm system requires more than simply choosing a loudspeaker with sufficient wattage. Different environments require different speaker construction, sound projection, mounting methods and loudspeaker-line supervision.

The BOSCH loudspeaker and PRAESENSA supervision solution provides options ranging from the LHM0606/00 6W ceiling loudspeaker for indoor announcements and background music to the LHM-10MGE, LHM-30MGE, LHM-50MGE and LHP-60CGE for more demanding marine and industrial applications, together with PRA-EOL and PRA-EOB devices for supervised loudspeaker circuits.

This makes the range suitable for designing PA infrastructure across offices, commercial buildings, factories, warehouses, transportation facilities, marine environments and other professional installations.

BOSCH LHM0606/00 – 6W Ceiling Mount Speaker

The BOSCH LHM0606/00 is a compact ceiling loudspeaker designed for clear speech reproduction and background music in general indoor PA applications.

Its discreet ceiling-mounted design makes it suitable for areas where sound coverage is required without large visible loudspeakers.

The LHM0606/00 provides a 6W rated output with selectable 6W, 3W and 1.5W transformer taps. The loudspeaker has an effective frequency range of approximately 80Hz to 18kHz, allowing it to reproduce both speech announcements and general background music. (Bosch Security Resources)

Ideal Applications for LHM0606/00

The 6W ceiling loudspeaker is well suited to:

Office • Reception • Meeting Room • Retail Shop • Corridor • Classroom • Commercial Building • Waiting Area • General PA

Its wide sound dispersion makes it particularly useful where several ceiling speakers can be distributed throughout an area to achieve more consistent sound coverage.

Optional Fire Dome for LHM0606/00

For installations requiring additional protection, the LHM0606/00 can be fitted with the compatible LBC 3080/01 protective steel fire dome.

The fire dome mounts behind the loudspeaker and provides additional mechanical and cable protection. (Bosch Security Resources)

Whether a particular installation meets a fire, evacuation or regulatory requirement depends on the complete PA/Voice Alarm system design, not on the loudspeaker alone.

The LHM-10MGE belongs to the marine/industrial loudspeaker family and is intended for applications where a conventional indoor ceiling speaker would not be appropriate.

Its lower-power positioning makes it useful where clear local announcements are required without the output level of the larger marine models.

Potential applications include:

Marine Areas • Shipboard PA • Industrial Facilities • Machinery Areas • Utility Spaces • Outdoor/Harsh Environments

For marine projects, speaker selection should consider the required coverage area, ambient noise level, mounting position, environmental exposure and applicable project certification requirements.

The LHM-30MGE provides a step up in output for larger or noisier environments.

A higher-output horn-style loudspeaker can project speech more effectively over distance and against elevated background noise compared with a conventional low-power ceiling speaker.

Typical applications can include:

Ship Deck Areas • Workshops • Industrial Plants • Warehouses • Loading Areas • Machinery Spaces • Marine Facilities

Correct loudspeaker quantity and spacing should be calculated according to the required sound-pressure level and intelligibility rather than simply selecting the highest wattage.

For applications requiring still greater sound output, the LHM-50MGE provides a higher-power option within the marine loudspeaker range.

It can be considered for larger areas or locations with substantial environmental and machinery noise where announcements need stronger acoustic projection.

Potential environments include:

Marine Vessels • Shipyards • Heavy Industry • Large Workshops • Outdoor Process Areas • High-Noise Facilities

For critical announcements, the objective is not merely loudness. Speech intelligibility is essential.

Speaker direction, mounting height, reverberation, ambient noise and amplifier power all affect the final result.

The LHP-60CGE provides another higher-output loudspeaker option for demanding marine and industrial PA applications.

It can form part of a professional distributed PA design where powerful speech reproduction is needed across challenging environments.

For marine installations, equipment should always be selected against the exact project’s environmental and approval requirements. A product being described as a marine loudspeaker should not automatically be taken to mean that every complete installation satisfies every maritime or vessel-classification requirement.

From Office Ceiling to Marine Environment

One of the strengths of this product group is the ability to select different speaker types for different zones while maintaining a coordinated PA design.

For example:

Office Area → LHM0606/00 Ceiling Speakers

Workshop → Higher-Output Loudspeakers

Outdoor / Industrial Area → Marine/Industrial Loudspeakers

High-Noise Area → Higher-Power Directional Speakers

Marine Area → Appropriate LHM/LHP Marine Speaker

This is much more effective than installing one loudspeaker type throughout an entire facility regardless of the acoustic environment.

100V Distributed PA System

The LHM0606/00 and appropriate professional PA loudspeakers can form part of a distributed 100V line PA architecture.

A 100V loudspeaker system is particularly useful for installations requiring multiple loudspeakers over larger cable distances.

Each compatible loudspeaker can use an appropriate transformer tap so that the system designer can control the amount of amplifier power allocated to each speaker.

For example, several low-power speakers can be distributed through offices and corridors while higher-power speakers serve noisy or outdoor areas.

The total connected loudspeaker load must remain within the amplifier and system-design limits.

Why Loudspeaker-Line Supervision Matters

For normal background music, a disconnected loudspeaker is inconvenient.

For an emergency communication system, a disconnected loudspeaker circuit can be much more serious.

A supervised system helps identify faults before an emergency occurs.

Depending on the complete system architecture, supervision can assist in detecting conditions such as:

Open Circuit • Short Circuit • Loudspeaker-Line Failure • Branch Failure

This allows maintenance personnel to investigate and rectify the problem rather than discovering it only during an actual emergency.

BOSCH PRAESENSA Voice Alarm Integration

PRA-EOL and PRA-EOB are designed for use within the PRAESENSA IP-connected Public Address and Voice Alarm ecosystem.

A complete professional solution may incorporate:

System Controller → Network Amplifier → Loudspeaker Zones → PRA-EOL / PRA-EOB → Loudspeakers

Depending on the system design, different zones can use ceiling speakers, wall speakers, horn loudspeakers or marine loudspeakers according to their acoustic and environmental requirements.

PA Speaker Selection – Wattage Is Not Everything

Choosing a loudspeaker based only on “6W, 10W, 30W, 50W or 60W” is not good PA engineering.

Several factors should be considered:

Ambient Noise – A machinery area needs more acoustic output than a quiet office.

Coverage Distance – A ceiling speaker covering a small room has a different requirement from an outdoor horn projecting across a large area.

Speech Intelligibility – Emergency messages must be understandable, not merely loud.

Environment – Indoor, outdoor, industrial and marine areas have different physical requirements.

Mounting Position – Ceiling height, direction and spacing affect coverage.

Amplifier Capacity – The total loudspeaker load must be correctly matched to the amplifier.

Cable Supervision – Voice Alarm applications may require monitored speaker circuits.

Suitable Applications

This Bosch speaker and supervision range can be considered for appropriately engineered systems serving:

Commercial Buildings – paging and background music.

Offices – announcements and distributed ceiling audio.

Factories – higher-output announcements in operational areas.

Warehouses – paging over larger spaces.

Marine & Shipboard Environments – appropriate marine loudspeaker applications.

Transportation Facilities – distributed announcements across multiple zones.

Industrial Facilities – higher-output speakers for challenging environments.

Voice Alarm Systems – supervised loudspeaker circuits using appropriate PRAESENSA equipment.

One BOSCH PA Solution – Different Environments

A well-designed PA system can therefore combine different technologies according to each zone:

LHM0606/00
6W ceiling speaker for indoor speech and background music.

LHM-10MGE
Marine/industrial loudspeaker for appropriate lower-output applications.

LHM-30MGE
Higher-output marine/industrial speaker for larger or noisier zones.

LHM-50MGE
Higher-power marine loudspeaker for demanding environments.

LHP-60CGE
High-output marine loudspeaker for appropriate heavy-duty applications.

The result is a more complete solution covering sound reproduction + environmental requirements + loudspeaker-line supervision.

Bosch Horn Speaker Range

The marine-certification distinction is important: Bosch currently explicitly lists MED marine certification for LHM-10MGE and LHM-30MGE. The LHM-50MGE, LHE models and LHP-60CGE should not automatically be advertised as MED-certified simply because they belong to the same new horn family. (commerce.keenfinity.tech)

BOSCH LHE-10CGE — 10W

The LHE-10CGE is an economical 10W horn loudspeaker designed for clear speech and alarm-tone reproduction. Its compact enclosure uses glass-reinforced ABS, carries an IP66 rating and provides an internal installation option for either PRA-EOL or PRA-EOB supervision hardware. It is EN 54-24 certified. (commerce.keenfinity.tech)

Best suited for general paging, corridors, sheltered external areas, schools, warehouses and commercial premises.

BOSCH LHE-30CGE — 30W

The LHE-30CGE provides the same Entry-level concept with a more powerful 30W compression driver.

It is the logical step up where greater sound pressure or coverage is required while retaining the compact IP66 glass-reinforced ABS enclosure, smart installation bracket and PRA-EOL/PRA-EOB provision. (commerce.keenfinity.tech)

MID LEVEL — LHM Marine-Capable Series

The LHM family moves to a more rugged aluminium and PPE construction with a stainless-steel smart bracket. (commerce.keenfinity.tech)

BOSCH LHM-10MGE — 10W

The LHM-10MGE uses a 10W compression driver with IP66 construction and is officially listed with:

EN 54-24 Fire Safety Certification

MED Marine Certification

PRA-EOL / PRA-EOB Provision

This makes it particularly interesting for projects involving marine and demanding industrial environments, subject to the complete project’s certification requirements. (commerce.keenfinity.tech)

BOSCH LHM-30MGE — 30W

The LHM-30MGE increases output to 30W and currently carries the strongest published certification combination among these Mid models:

EN 54-24

UL 1480

MED Marine

IP66

For marine-related specifications requiring more acoustic output, this is particularly attractive.

BOSCH LHM-50MGE — 50W

For industrial locations requiring greater output, the LHM-50MGE provides a powerful 50W compression driver.

It retains the rugged aluminium/PPE enclosure, IP66 rating, stainless-steel bracket and PRA-EOL/PRA-EOB installation provision. Bosch currently lists it as EN 54-24 certified. (commerce.keenfinity.tech)

Do not automatically describe the LHM-50MGE as MED Marine certified unless the exact supplied product’s current certificate confirms it.

The BOSCH LHP-60CGE is different from the conventional speech-focused horns because it is a:

60W 2-WAY MUSIC HORN LOUDSPEAKER

Bosch specifies a 2-way system, 60W compression driver, glass-reinforced ABS housing, IP66 protection, smart bracket and internal PRA-EOL/PRA-EOB provision. It is also EN 54-24 certified. (commerce.keenfinity.tech)

This makes the LHP-60CGE especially attractive where the PA system is expected to provide both:

Emergency / Operational Announcements

and

Higher-Quality Background Music

while still using a horn-style loudspeaker.

Marine Applications

For marine projects, model selection requires more than looking for an IP rating.

IP66 primarily addresses ingress protection. Marine certification addresses additional requirements relevant to marine installations.

Within this particular new range, Bosch explicitly lists:

LHM-10MGE — MED Marine Certified

LHM-30MGE — MED Marine Certified

(commerce.keenfinity.tech)

Bosch also has dedicated marine horn products elsewhere in its portfolio. For example, its LH2 marine range includes models engineered for humid, chlorine and salt-containing environments, with applicable marine type approvals depending on model. (resources-boschescurity-cdn-hre9eue8h0fefmcd.a02.azurefd.net)

Therefore, for ships, offshore facilities, shipyards and marine terminals, the exact required marine standard should be established before selecting a model.

Recommended Selection

For economical general PA, start with LHE-10CGE.

For higher-output economical PA, use LHE-30CGE.

For 10W marine-certified applications, consider LHM-10MGE.

For 30W marine-certified and demanding PA/VA applications, LHM-30MGE is particularly strong.

For higher-output industrial applications, consider LHM-50MGE.

For high-output voice plus better music reproduction, select the LHP-60CGE 60W 2-way music horn.

For supervised PRAESENSA speaker circuits, select PRA-EOL or PRA-EOB according to the actual loudspeaker-line topology.
