Start With Your Venue and Audience
Before you look at a single speaker spec, get to know your venue and your crowd. A setup that sounds brilliant in a small hall can sound thin and echoey in an open marquee, or muddy in a room full of hard, reflective surfaces.
Reading the Room's Acoustics
Soft surfaces, carpets, curtains, a room full of people, absorb sound, which cuts down on echo but can mean you need a bit more power to fill the space. Hard surfaces, glass, concrete, bare walls, bounce sound around and create reverberation, making speech harder to follow. In a "live" room like this, where you place your speakers matters more than usual.
Sizing Up Your Audience
A 50-person indoor gathering and a 200-person outdoor event have genuinely different requirements. A smaller indoor crowd is often well served by a single portable PA unit. A larger outdoor crowd usually needs more power and, in some cases, additional speakers to maintain even coverage without distortion at the source.
Active vs Passive Speakers
One of the first real decisions is active versus passive. An active speaker has the amplifier built into the cabinet, a self-contained, plug-and-play unit. A passive speaker is just the speaker itself, with no power of its own, and needs a separate external amplifier to do anything.
Active Speakers: The Simple Choice
For most small to medium events in New Zealand, active speakers are the practical default. There's no matching an amplifier to a speaker driver and no complex wiring, you plug it into power, connect your audio source, and you're set. This suits mobile DJs, corporate presentations, and community events where quick setup and pack-down matter.
Passive Speakers: Built for Scale
Passive systems trade convenience for flexibility. Choosing your speakers, amplifier and mixing desk independently lets a sound engineer build a genuinely customised setup for a large venue or a complex event, and if one component fails, you replace that part rather than an entire self-contained unit. This is the standard for concerts, festivals and larger professional live sound, not a typical small function.
If you need a straightforward, no-fuss setup without a dedicated sound technician, active is almost always the right call. If you're running something with serious power needs, multiple sound sources, or fine-tuned control, that's when a passive rig earns its complexity.
Power, Cables and the Gear People Forget
Even the best speakers are just heavy boxes without reliable power and the right leads. This is the logistical side that's easy to overlook and can bring an event to a stop if it's not sorted in advance.
Check the Power Situation First
Before plugging anything in, find out where the power outlets are, how many circuits serve the area, and each circuit's amperage limit. Tally the total power draw of your gear, speakers, mixer, lights, and keep your total load comfortably under the circuit's maximum capacity, leaving margin rather than running right up to the limit. Tripping a breaker mid-speech is avoidable with a five-minute check beforehand.
Don't Skimp on Cables
Cheap, worn cables are a common point of failure, prone to damage and capable of introducing noise, crackling, or a dropped signal entirely. XLR cables are the standard for microphones and linking speakers, with a locking three-pin design that resists interference over longer runs. Jack plugs (TS/TRS) connect instruments, laptops or phones. Speaker cables connect an amplifier to passive speakers. Run cables safely along walls or tape them down, never stretched tight across a walkway.
The Accessories That Get Forgotten
Sturdy speaker stands matter more than people expect, since sound needs to travel over the crowd's heads to reach the back of the room clearly. Sort out microphone stands too, a boom stand for a seated speaker or an acoustic instrument, a handheld or lapel setup for a presenter who needs their hands free.
Getting Speaker Placement Right
Where you put your speakers matters as much as which ones you chose. Good placement is what separates clear, even audio from a muffled, patchy mess.
Get Speakers Off the Floor
Sound waves travel in a straight line. Speakers left on the floor or a low table fire sound into the backs of the people standing closest, while the rest of the room gets a dull, muddy result as clarity gets absorbed before it travels. Raising speakers to at least head height lets sound travel over the crowd and reach the back of the room intact, a simple change that makes any setup sound noticeably more professional.
Building a Stereo Image for Music
For any event where music matters, a party, a wedding reception, a DJ set, place your two main speakers on either side of the stage, forming a rough triangle with the audience. The sweet spot has roughly equal distance between the two speakers and from each speaker to the centre of the audience, giving listeners in the middle a proper stereo experience rather than a lopsided one.
Awkward Room Shapes
A long, narrow room or an L-shaped venue can leave people near the front overwhelmed and people at the far end straining to hear. Delay speakers, smaller units placed further down the room playing the same audio with a slight electronic delay, compensate for the travel time of sound and keep everyone hearing it at effectively the same moment.
Avoiding Feedback
Feedback happens when a microphone picks up sound from a speaker, which gets re-amplified in a loop. The simple fix: never point a microphone directly at a speaker. Position speakers so the presenter or performer stands behind them, aimed out at the audience, which is the most reliable way to avoid that squeal without sacrificing volume.
Why Hiring From a Specialist Beats a Big-Box Store
For a one-off event, hiring makes more sense than buying, both practically and financially. The bigger question is where you hire from. A large department store might seem convenient, but it typically stocks a narrow range of consumer-grade gear, and staff often can't advise on what your specific event actually needs.
A specialist provider works differently. Before recommending anything, we'll ask how many people you're expecting, whether the audio is mainly speeches, background music, or a live band, and what your power situation looks like on-site. That informs a genuinely matched recommendation, whether that's a simple portable PA for a school sports day or a more complex setup with a mixing desk and multiple microphone types for a corporate conference.
Specialist hire equipment is also built to a different standard: regularly tested and serviced, designed for clear projection and durability well beyond consumer gear, and supplied complete with the stands, cables and connectors you'll actually need, so you're not scrambling on the day.
Real PA Options from Mobile Systems
We supply and hire the Chiayo portable PA range, scaled from small indoor briefings through to larger outdoor events.
| Model | Output | Best For |
|---|---|---|
| Chiayo Coach 400 | 25W RMS (40W music), built-in UHF wireless mic receiver | Sports coaching, outdoor briefings, small tours |
| Chiayo Focus 505 Complete | 27W RMS, wireless mic receiver included | Classrooms, boardrooms, small presentations |
| Chiayo Stage Pro 1500 Complete | 150W RMS / 200W peak, built-in mixer | School assemblies, stage performances, mid-size functions |
| Chiayo Challenger C1000D Complete | 200W Class D, expandable with slave speakers | Larger events, crowds up to roughly 300 people, sports clubs |
All four are active, self-contained systems, so there's no separate amplifier to source or match. If your event is genuinely large-scale or needs a passive, professionally engineered rig, that's a conversation worth having directly with our team rather than assuming a bigger portable unit is the answer.
