FONESTAR VULKAN-50

Product overview

The FONESTAR VULKAN-50 is a low impedance exponential horn speaker from the VULKAN series: 50 W RMS, one compression driver, IP-66 protection and a low impedance (8 Ω) connection directly to the amplifier, for sending messages and warnings over long distances.

FONESTAR created the VULKAN range of horn loudspeakers for the wide range of installations where the sound signal must be sent with maximum efficiency. VULKAN horns are suited to the frequency range of speech and to sending messages over long distances. They are built with materials that are highly resistant to adverse weather, and the IP-66 design protects them against the ingress of dust and water, so they suit outdoor use and marine environments: open spaces, industrial facilities, sports facilities and car parks.

Key features

• Exponential horn speaker with one compression driver, 50 W RMS
• Low impedance, 8 Ω for direct connection to the amplifier
• 105 dB sensitivity (1 W / 1 m) and 122 dB maximum sound pressure
• 270-6,000 Hz (-10 dB) response for clear speech
• IP-66 in compliance with EN 60529, anti-corrosion materials
• Diffuser and ABS rear cover with high resistance to sun exposure, aluminium mount, A2 stainless steel screws
• 30 cm cable with stripped ends; grey RAL 7035

Long-range speech

The exponential horn concentrates the sound of the compression driver for messages, warnings and paging over long distances. The response of 270-6,000 Hz (-10 dB) covers the speech range, and the dispersion is 180°/160° @ 500 Hz, 140°/120° @ 1 kHz, 90°/80° @ 2 kHz, 50°/40° @ 4 kHz (-6 dB).

Direct low impedance connection

The VULKAN-50 is a low impedance (8 Ω) loudspeaker for direct connection to the amplifier in installations where a long cable run is not necessary: white wire to +, black wire to COM.

Built for harsh environments

Materials: diffuser and ABS rear cover with high resistance to sun exposure; aluminium mount; A2 stainless steel screws. IP-66 protection, operation from -25 °C to +55 °C, storage from -40 °C to +70 °C and humidity below 95% make it suitable for factories, sports facilities, hotels, transport stations.

Quick installation

Remove the mount from the horn, fix it to the wall or structure, configure the speaker, connect the cables and fit the horn back on the mount, aiming it at the listening area (official quick start guide).

Workflow 1: Factory announcements

Paging and warnings across noisy production halls and yards.

Connections

Setup

1. Fix the mounts high on walls or columns.
2. Connect the horn directly to the amplifier output (8 Ω).
3. Aim each horn along the working area.
4. Check speech clarity with machines running.

Tip: The horn shape concentrates speech for long-range messages.

Workflow 2: Sports ground

Announcements for open-air pitches and stands.

Connections

Setup

1. Mount the horns on posts or the stand roof.
2. Connect the horn directly to the amplifier output (8 Ω).
3. Aim them at the spectator areas.
4. Raise the level gradually to avoid feedback with microphones.

Tip: IP-66 protection suits fully exposed outdoor positions.

Workflow 3: Car park

Messages and alarms in open and covered car parks.

Connections

Setup

1. Place horns at the entrances and along the driving lanes.
2. Connect the horn directly to the amplifier output (8 Ω).
3. Use round cable and keep the cable gland tight.
4. Test messages from the paging console.

Tip: Use appropriate power, impedance and frequency limits, as FONESTAR advises.

Workflow 4: Transport station

Platform and forecourt announcements.

Connections

Setup

1. Install horns above the platforms facing the passengers.
2. Connect the horn directly to the amplifier output (8 Ω).
3. Keep similar settings on one platform for an even level.
4. Verify intelligibility at both ends of the platform.

Tip: Speech-range response keeps announcements clear over traffic noise.

Workflow 5: Marina or coastal site

Paging in harbours and seaside facilities.

Connections

Setup

1. Fix the aluminium mounts with A2 stainless steel screws.
2. Connect the horn directly to the amplifier output (8 Ω).
3. Route outdoor cable to the horns.
4. Aim the horns over the moorings or walkways.

Tip: FONESTAR states VULKAN horns suit marine environments.

Workflow 6: Hotel or campus grounds

Messages for gardens, pools and outdoor areas.

Connections

Setup

1. Mount the horns discreetly on walls or poles.
2. Connect the horn directly to the amplifier output (8 Ω).
3. Aim them at the open areas only.
4. Set the paging level for daytime use.

Tip: Use round outdoor cable and keep the cable gland tight.
