Professional sound systems
Sound for hospitality, clubs and business spaces.
Kooijman Connection designs and installs sound systems for hospitality, clubs, halls and business premises: background music per zone, paging, speech that is intelligible everywhere and sound that carries a club. With our own team, and management after handover.
What goes into a sound system?
A good sound system starts with the room: how big, how loud or quiet, and what needs to be heard. From there we choose loudspeakers, amplifiers and a processor that controls the sound per zone. Staff operate it from a wall panel or app: pick a source, set the volume per zone, done.
- 01Loudspeakers
- In-ceiling, surface or pendant, chosen for the room, interior and sound pressure.
- 02Amplifiers
- 100V for many speakers over long distances, low impedance for full sound.
- 03Processor (DSP)
- Controls tone, volume and delay per zone, and protects the system.
- 04Zones
- Bar, terrace, hall or warehouse each with its own source and volume.
- 05Microphones and paging
- Wireless microphones for speakers, a paging microphone for announcements.
- 06Control
- Wall panel or app: source, volume and zones without technical knowledge.
Move the faders. Each zone its own sound, run from one panel

ORYN
Media Park, Hilversum
In the long entrance hall of ORYN, the 5,830 m² event venue in the former Studio 21, Kooijman Connection hung Bose Professional DesignMax Luna pendant loudspeakers (DML88P). Their ring layout spreads the sound evenly through the hall, together with lighting and projection.

What does each space need?
A bar, a club, a hall and a warehouse each ask something different of sound.
| Hospitality and retail | Club | Hall and auditorium | Warehouse | |
|---|---|---|---|---|
| Goal | Background music, per zone | Volume and impact on the dance floor | Speech intelligible from every seat | Paging above the work |
| Loudspeakers | Many small ones, evenly spread | Powerful tops and subwoofers | Directional, matched to the acoustics | Horns or projectors with reach |
| Control | Wall panel per zone | DJ mixer with limiter | Panel with microphone scenes | Paging microphone and fixed messages |
| Watch out for | Even volume, no loud spots | Sound limits and neighbours | Reverberation | Ambient noise |
100V system or low impedance?
There are two ways to connect loudspeakers. The choice depends on the number of speakers and the sound you want.
| 100V system | Low impedance | |
|---|---|---|
| Suits | Many speakers over long distances | Fewer speakers with full sound |
| Typical place | Office, retail, warehouse, terrace | Club, hall, stage |
| Cabling | Long runs, thin cable is enough | Shorter distances, thicker cable |
| Expanding | Speakers are easy to add | An amplifier channel per group |
| Sound | Fine for speech and background music | Full reproduction and high volume |
Many spaces combine both: 100V for background music and paging, low impedance for the hall or dance floor.
What drives the cost of a sound system?
No fixed prices: every room sounds different. After an on-site meeting you receive a design with a quote. These are the factors.
- 01
Floor area and zones
More rooms and zones mean more speakers and channels.
- 02
Required volume
Background music needs less than a dance floor.
- 03
Type of loudspeakers
In-ceiling, pendant or design speakers that suit the interior.
- 04
Acoustics
A reverberant room calls for directional speakers or acoustic treatment.
- 05
Cabling and mounting
Ceiling, walls, and how the cables are hidden.
- 06
Control and microphones
Wall panels, app control and wireless microphones.

Frequently asked questions about sound systems
01What is a 100V sound system?
In a 100V system the amplifier works at a high voltage, so many loudspeakers can share one long cable. That is ideal for background music and paging in offices, shops and warehouses. For full sound at high volume we choose a low-impedance system.
02Can we set different music or volume per room?
Yes. We divide the building into zones, such as bar, terrace and hall. Per zone staff choose the source and volume on a wall panel or in an app.
03Is a paging system the same as a voice evacuation system?
No. A paging system is for announcements and music. A voice evacuation system (in the Netherlands under NEN 2575) is required in certain buildings and must be certified. During the inventory we tell you what applies to your building.
04Do I have to pay for music in my business?
Yes. In the Netherlands, playing music in a business or hospitality venue requires a licence from Buma/Stemra and Sena. That is separate from the installation.
05Which brands do you work with?
Among others Bose Professional, RCF, Shure and Sennheiser. We choose per room on sound, look and budget; the design names the models we propose.
Does your space sound the way you want?
Book an on-site meeting. We listen to the room and advise the sound that suits it.
