Line Array vs Point-Source Speakers — Which One for My Hall?
A plain-language comparison: how each works, when a line array is worth the cost, and when a pair of good boxes is the smarter choice.
"Should we buy a line array?" is one of the most common questions we hear. The honest answer depends on the room length, the audience and the budget — not on what looks impressive on stage.
How a point-source speaker behaves
A single box (itc KS-10H, KF-D15H) radiates from one spot. Its level falls about 6 dB every time the distance doubles, so the front row hears it far louder than the back. In short rooms that difference is acceptable; in long rooms it is not.
How a line array behaves
A line array (itc KS-210, LA-2800K) stacks identical boxes in a curved column. Over its working range it behaves like a long source whose level falls more slowly with distance, and its vertical coverage can be shaped by the splay angles to fit the seating. The result is a more even level front-to-back and less energy wasted on the ceiling.
Rules of thumb
- Rooms under about 20–25 m deep: point-source speakers are usually the better value.
- 25–50 m, or balconies: a compact line array (4–8 boxes per side) gives clearly better coverage.
- Outdoor events and stadiums: line arrays plus delay towers or distributed fills.
- Low ceilings: point-source or distributed speakers — there is no room to hang an array properly.
Do not forget the rest of the system
Either choice needs correct amplification, subwoofers sized to the music, processing for EQ and delay, and a good mixer. A well-tuned pair of boxes beats a badly-tuned array every time.

Frequently asked questions
Is a line array always louder?
Not louder — more even. It delivers similar level to the front and back rows, which lets the overall level stay lower and clearer.
Can we start with point-source and move to an array later?
Yes; the amplifiers, mixer and subwoofers can usually be reused when the mains are upgraded.
