Indoor or Outdoor Sound System: How to Choose

Rigging an indoor sound system and rigging an outdoor one are not the same job. Where the event happens changes how sound travels, and therefore how the system has to be sized. This guide covers the main differences and what to weigh up before you plan your event.

Sizing changes with the location

The most important difference is how much power you need:

• Indoors the walls reflect sound. The reverberation helps fill the room, so you need less power and a more modest system will do.
• Outdoors there’s no reverberation: sound disperses into the air and falls away quickly with distance. Covering the same number of people takes considerably more power — often two or three times what you’d need inside.

In practice, the same guest count needs a noticeably bigger system when the event moves outdoors.

Subwoofers and delay speakers

Outdoors, low frequencies are the first thing to disappear. That’s why subwoofers become close to essential: without them the music sounds thin and bodiless, especially on the dancefloor.

When the area is large or long, delay speakers come into play as well: additional cabinets placed further from the stage and time-aligned electronically, so people at the back get a clear sound without having to push the level uncomfortably high at the front.

The electrical supply question

One aspect that’s often underestimated at outdoor events is power. Gardens, countryside venues and remote properties don’t always have sockets rated for the load. In those cases you need a properly sized generator:

• it has to cover the combined draw of audio, lighting and any effects;
• it needs to sit far enough away to keep the noise down;
• it takes planning in advance — it isn’t something you improvise on the day.

Indoors the existing supply is usually sufficient, but it’s still worth checking.

Weather and cover

The other big unknown outdoors is the weather. Rain, humidity and wind can damage equipment and ruin the evening. Which is why it’s essential to:

• provide cover (a marquee, a canopy, a roof) for the desk and the speakers;
• have a plan B for bad weather;
• protect cables and connections from water and foot traffic.

Indoors those problems don’t exist, but you do need to think about acoustics and room capacity.

Why the site visit matters

Whichever you choose, the site visit is what makes the difference. Seeing the venue beforehand lets us assess the space, the distances, the power points, the acoustics and the access, so the day itself holds no surprises.

In short: indoors is simpler to manage, while outdoors demands more power, subwoofers, and attention to power supply and weather. In both cases, a professional production company adapts the build to the real conditions of the place.
