For clubs, bars, restaurants, boardrooms, museums and theatres

At 285 x 189 x 178 mm and 4.9 kg, the 4030C reaches 104 dB SPL with a response down to 47 Hz: enough output and bass extension for small to medium-sized rooms, with GENELEC reliability around the clock.

Minimum Diffraction Enclosure and DCW waveguide

The die-cast aluminium Minimum Diffraction Enclosure (MDE) has rounded edges and gently curved surfaces that reduce edge diffraction; the Directivity Control Waveguide (DCW) shapes the tweeter's dispersion. Together they give a flat response on and off axis, fewer early reflections and an excellent frequency balance in difficult acoustic environments.

Euroblock input with daisy-chaining

Audio enters through a balanced 10 kOhm Euroblock connector. Wire the signal cable to the supplied 3-pole plug; to feed several speakers from one source, connect a second cable to the same plug and route it to the next 4030C. The LEVEL control (-40 dB range) matches the input to the source: -6 dBu gives 100 dB SPL at 1 m with the control at maximum.

Room response controls

Treble Tilt boosts the treble above 5 kHz by +2 dB to compensate for the high frequency loss at long listening distance. Bass Roll-Off adds -4 dB at 55 Hz for heavy bass near room boundaries, and Bass Tilt gives -2, -4 or -6 dB below 2 kHz. The factory setting is all OFF for a flat anechoic response.

Versatile mounting

A 3/8 in UNC thread in the base fits a standard microphone stand, and two M6x10 mm threaded holes on the rear take brackets or the supplied keyhole wall mount adapter. A simple bracket and mounting screw set come in the box, and GENELEC offers table and floor stands, ceiling, truss and wall mounts for the 4030C.

In the box

• 1 x GENELEC 4030C installation speaker
• 1 x 3-position terminal block
• 1 x mains cable (1.8 m)
• 1 x simple bracket
• 1 x mounting screw set
• 1 x operating manual

GENELEC 4030C: frequently asked questions

Does the 4030C need a separate amplifier?

No. Two 50 W Class D amplifiers are built in. Connect a line-level source to the balanced Euroblock input; never connect it to the speaker outputs of an amplifier or receiver.

Can several speakers share one signal?

Yes. Connect a second signal cable to the 3-pole plug and route it to the next speaker (daisy-chaining).

Which colours are available?

Black and White as standard; RAW aluminium and any of 120 RAL colours can be ordered as custom finishes.

How much space does it need around it?

In a cabinet or wall structure keep at least 3 cm free behind, above and at both sides, open to the room, with the ambient temperature below 35 °C.

Where can I buy the GENELEC 4030C in India?

The GENELEC 4030C is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: Club or bar

Music with clarity and output for a small to medium-sized venue.

Connections

Setup

1. Mount the speakers with the acoustic axes aimed at the centre of the listening area.
2. Wire the balanced cables to the 3-pole plugs and push them in.
3. Set all tone switches OFF, then choose settings for the mounting position.
4. Connect the earthed mains cables, switch on and set the LEVEL controls.

Tip: Vertical placement is preferred: it minimises cancellation around the crossover frequency.

Workflow 2: Daisy-chained zone

Several speakers in one zone fed from a single line output.

Connections

Setup

1. Run a balanced cable from the zone output to the first speaker.
2. Connect a second cable to the same plug and route it to the next speaker.
3. Repeat for each speaker in the zone.
4. Match the levels with each speaker's LEVEL control.

Tip: Daisy-chaining saves cable runs back to the rack in long rooms and corridors.

Workflow 3: Restaurant or bar

Clean, non-fatiguing music at any playback level.

Connections

Setup

1. Choose black, white or a custom RAL colour to blend with the interior.
2. Mount the speakers clear of reflecting surfaces and aim them at the seating areas.
3. Use Bass Tilt near walls and Bass Roll-Off for heavy bass near boundaries.
4. Leave ISS ON so the system goes to standby after closing.

Tip: GENELEC's online colour picker previews the speaker in the 120 RAL colours.

Workflow 4: Museum or theatre foyer

Narration, soundscapes and announcements for visitors.

Connections

Setup

1. Place the speakers where the audience listens, aimed at ear height.
2. Keep at least 3 cm free space around them inside any enclosure.
3. Use Treble Tilt +2 dB if the listening distance is long.
4. Set the levels with the LEVEL control.

Tip: Controlled directivity keeps the sound clear and intelligible in reverberant rooms.

Workflow 5: Meeting room or boardroom

Clear speech for presentations and video calls.

Connections

Setup

1. Mount the speakers on either side of the display.
2. Aim the acoustic axes at the table.
3. Set Bass Tilt for wall mounting (near a wall: -6 dB).
4. Set the LEVEL controls for a comfortable speech level.

Tip: The compact enclosure fits beside a display without dominating the room.

Workflow 6: Energy-saving everyday use

Leave the system ready all day without wasting power.

Connections

Setup

1. Set the ISS switch to ON.
2. After playback has ended for a while the speaker goes to standby, below 0.5 W.
3. It wakes automatically when audio arrives; there is a slight delay.
4. If the delay is unwanted, set ISS to OFF and use the power switch.

Tip: Only removing the mains cable disconnects the amplifier completely from the mains.
