When an event planner, venue manager, or production company asks for "a sound system," the most important decision is not the brand. It is the type of system: line array or point source.
These two architectures behave differently, sound different, and suit different situations. Choosing wrong means either overspending on a system you do not need or underpowering an event that deserves better.
Here is how they work and when to use each.
How a Point-Source Speaker Works
A point-source speaker is a single cabinet (or a stack of cabinets) that radiates sound from one location. Think of the classic speaker-on-a-stand at a small gig, or a larger cabinet on a tripod at a corporate presentation.
Sound from a point source spreads outward in a cone shape. The coverage angle is fixed by the horn design, typically 60 to 120 degrees horizontal and 40 to 60 degrees vertical. People close to the speaker hear it louder. People far away hear it quieter. That drop-off follows the inverse square law: double the distance, lose 6 dB.
Examples: JBL SRX800 series, Electro-Voice ELX200, L-Acoustics X Series, QSC KLA.
When Point Source Works Best
- Small to medium events (up to 200 guests). A pair of quality point-source speakers handles this crowd comfortably.
- Indoor venues. Walls help contain and reflect sound, extending effective coverage.
- Seated audiences. When the audience is not deep (few rows), the front-to-back volume difference stays manageable.
- Speech and presentation. Clarity at moderate volume, where even coverage is less critical than intelligibility.
- Budget-conscious events. Point-source systems cost less to rent, transport, and set up.
Limitations
The 6 dB-per-doubling drop-off becomes a problem at scale. At an outdoor event with 300+ guests, the front row is uncomfortably loud while the back cannot hear properly. You can add more speakers (delay fills), but at that point you are fighting physics rather than solving the problem.
How a Line Array Works
A line array is a series of identical speaker cabinets (called elements) hung vertically in a curved column. Each element covers a narrow vertical slice of the audience, and together they create a coherent wavefront that covers the entire area.
The key difference: a line array's volume drops at 3 dB per doubling of distance (cylindrical wave propagation), not 6 dB like a point source (spherical wave). That means the volume difference between the front row and the back is much smaller. Everyone hears a similar level.
Additionally, each element's angle is individually adjusted during rigging. The top elements aim at the back of the audience. The bottom elements aim at the front. The result is even coverage from front to back, with no hot spots and no dead zones.
Examples: L-Acoustics K2, KARA II, A Series; JBL VTX; d&b audiotechnik; Meyer Sound.
When Line Arrays Win
- Large events (300+ guests). The even coverage makes a line array necessary once the audience depth exceeds what point source can handle.
- Outdoor events. Without walls to help, you need the controlled dispersion and slower level drop-off that line arrays provide.
- Events with artist riders. Most professional DJs and live acts specify line arrays. It is what they are used to hearing, and it is what their engineers know how to tune.
- Multi-zone venues. Different array elements can be aimed at different areas, and delay hangs can extend coverage to secondary zones.
- High SPL requirements. Line arrays scale by adding elements. Need more output? Add more boxes. The system stays clean and coherent.
Limitations
Cost. A line array system requires more cabinets, dedicated amplifiers (often one amp channel per element), rigging hardware, and skilled engineers. It is the right tool for the job at scale, but overkill for a 50-person dinner.
Rigging complexity. Line arrays hang from trusses or ground-stack on specialised frames. This adds setup time and requires certified rigging knowledge.
Real-World Comparison: Mykonos Events
Here is how the choice plays out at typical Mykonos events:
Villa wedding, 120 guests, courtyard dining + pool area
Best choice: Point source. A pair of JBL SRX835P full-range speakers on stands for the dining area, a compact sub underneath, and a smaller pair for cocktail-hour coverage by the pool. Clean, adequate, and proportional to the space.
A line array here would be too much visually and physically. The rigging frames would dominate the intimate setting.
Beach party, 400 guests, open sand
Best choice: Line array. An L-Acoustics KARA II system, eight elements per side, with KS28 subwoofers. The open-air environment and deep audience area demand the even coverage and throw distance that only a line array provides. Point-source speakers would leave the back third of the crowd in a dead zone.
Corporate gala, 250 guests, hotel ballroom
Best choice: It depends. A good point-source system can handle this if the room is not too deep and the ceiling is reflective. But if the room is large, L-shaped, or the client is doing a DJ set after speeches, a compact line array (L-Acoustics A10 or KARA II in short hangs) gives better results.
Festival stage, 2,000+ attendees
Best choice: Line array, no question. L-Acoustics K2 or K1 main hangs with delay towers for the back. Multiple subwoofer stacks. This is the only way to cover a crowd this size with consistent quality.
The Hybrid Approach
For complex venues, the best solution is often a combination. Line arrays handle the main coverage area. Point-source speakers fill in specific zones: a cocktail area, a VIP section, an entrance corridor.
This hybrid approach is common at Mykonos weddings where the ceremony, dinner, and party happen in three different spaces within the same venue. Each space gets the system that suits it, all running from a single mixing position.
How to Decide
Ask these questions:
1. How many guests, and how spread out? Over 200 in an outdoor or deep space: lean toward line array.
2. Indoor or outdoor? Outdoor almost always favours line arrays for events over 150 people.
3. Is there an artist rider? If so, it probably specifies line arrays.
4. What is the budget? Point source is more affordable. But underpowering a large event to save money results in a worse experience for everyone.
5. What does the venue allow? Some venues have weight limits on rigging points or restrictions on speaker placement.
Your sound provider should recommend the system based on these factors, not upsell the bigger rig for the sake of it.
Soundme Events Can Advise
We stock both line array (L-Acoustics KARA II, JBL VTX) and point-source systems (JBL SRX, Electro-Voice). We recommend based on what your event actually needs.
