Comparisons
Line Array vs Point Source Speakers
Line array and point-source speaker systems are the two main approaches to PA sound reinforcement, and the right choice depends heavily on room shape, throw distance and audience size. Here's how they compare and which suits different Kenyan venues.
How Each System Works
A point-source system uses one or a small number of full-range speakers per side, radiating sound outward from a single point — simple, familiar and effective for smaller or wider spaces. A line array stacks multiple speaker elements vertically, using wave physics to control vertical dispersion and throw sound evenly over long distances with more consistent volume from front to back.
Side-by-Side Comparison
| Factor | Point Source | Line Array |
|---|---|---|
| Best room shape | Wide, shallow rooms | Long, narrow halls or outdoor throw distances |
| Coverage consistency over distance | Volume drops noticeably further back | More even volume from front to back rows |
| Setup complexity | Simple — speakers on stands or wall mounts | Requires rigging, flying and careful angle calculation |
| Cost | Lower for equivalent room size | Higher due to more elements and rigging hardware |
| Portability | Quick to set up and move | Slower setup, needs trussing or flying points |
| Typical use | Small-to-mid venues, churches, bars, conference rooms | Large auditoriums, outdoor festivals, arenas |
When to Choose Point Source
- Smaller churches, bars, lounges and conference rooms under roughly 300 seats
- Wide, shallow rooms where vertical throw control matters less than horizontal spread
- Budget-conscious projects that don't need rigging infrastructure
- Multi-purpose halls needing speakers that can be moved and reconfigured easily
When to Choose Line Array
- Long, narrow sanctuaries or halls where the back rows are far from the stage
- Outdoor events and festivals needing controlled, even throw over long distances
- Large auditoriums seating several hundred to thousands
- Any venue where minimising volume difference between front and back rows is a priority
Bigger isn't always better
A line array in a small, wide room is often overkill and can actually give worse coverage than a well-placed point-source pair, since line arrays are optimised for long vertical throw, not wide rooms.
Cost Implications
Line arrays cost more not just per speaker but also in rigging hardware, trussing, and the installation time needed to properly angle each element. For rooms under about 15 metres deep, a well-specified point-source system is usually both cheaper and acoustically better suited.
Frequently asked questions
Is a line array always louder than point source?+
Not necessarily louder overall, but a line array maintains more consistent volume across a long room, whereas point source systems lose significant volume toward the back in large spaces.
Can a small church use a line array?+
It's possible, but usually unnecessary and more expensive than needed — a well-placed point-source system typically performs as well or better in small-to-mid-size sanctuaries.
Which is better for outdoor events?+
Line arrays are generally preferred for outdoor events with large crowds, since they throw sound evenly over long distances, which is especially valuable outdoors where there are no walls to reinforce sound.
Does a line array need special rigging?+
Yes, line arrays require proper flying/rigging hardware and structural points to hang safely, which point-source systems on stands or poles do not need.
Is point source cheaper to hire for an event?+
Yes, point-source systems are generally cheaper to hire and quicker to set up than line arrays, making them a common choice for small-to-mid-size events on tighter budgets.
