A Complete Guide to Event Audio Requirements

A Complete Guide to Event Audio Requirements

Not only visuals—the LED screens and the stage lighting bring impact to the event. However, sound is the "invisible" element that can make or break the experience. If your audience can’t hear the speaker clearly or the music feels thin, the impact of your event is lost.

At Heavy Duty AV, we believe in using the right tool for the right job. Here is a breakdown of how to choose the heart of your sound system: the speakers.

 

1. Choosing the Right Speaker System

The "size" of the speaker doesn't always determine the quality; the technology behind it does. Here are the three most common configurations we provide:

A. PS15 Full-Range Speaker + LS18 Subwoofer

Professional Nexo PS15 full-range speaker paired with Nexo LS18 subwoofer for high-end corporate event audio.

At Heavy Duty AV, we believe that a subwoofer isn’t just an "extra"—it is essential to completing the audio spectrum. While the PS15 is a powerful full-range speaker, pairing it with the Nexo LS18 Subwoofer is our standard for almost every event.

  • Why the LS18 is Mandatory: A subwoofer handles the low-end frequencies that standard speakers can't reach. Without it, you lose the "warmth" of background music and the "impact" of videos. We include the LS18 to ensure a rich, high-fidelity sound that covers the full frequency range from top to bottom.

  • Best For: Nearly every event scene. Whether it’s a high-end Gala Dinner, a cinematic Product Launch, or a Live Band performance, this combo is the baseline for professional quality.

  • The Exception: We only recommend the PS15 on its own for speech-only events (such as basic press conferences or stand-up announcements) where music and video playback are not required.

  • The Heavy Duty Benefit: You get a concert-grade audio spectrum in a compact setup that delivers power without cluttering your event space.

     

B. Turbosound iQ15 + iQ18B (Active Powered System)

 Turbosound iQ15 active speaker and iQ18B powered subwoofer setup, ideal for space-saving event control areas.

For setups that require high-performance digital integration and a faster setup time, we offer the Turbosound iQ Series. Unlike our passive systems, these are Active Speakers, meaning the amplifiers are built directly into the units.

  • Space-Saving Efficiency: We specifically recommend this active system when the control console area is small. Since the power amplifiers are built into the speakers, we don't need extra space for bulky amplifier racks. This keeps your event floor clean and uncluttered.

  • Full Spectrum Power: By pairing the iQ15 with the iQ18B subwoofer, we maintain our commitment to a full audio spectrum—delivering deep bass and clear highs without the need for external power gear.

  • Why choose it? It is the perfect "all-in-one" powerhouse for venues with limited space, such as E-Sports booths, small stages, or high-traffic roadshows.

     

C. Curv 500PS (Column Array Systems)

Sleek LD Systems Curv 500PS column array speaker with subwoofer for luxury showrooms and shopping mall roadshows.

If you are looking for a sleek, modern aesthetic that blends seamlessly into high-end environments, the LD Systems Curv 500PS is our top recommendation.

  • Best for Roadshows & Showrooms: We specifically recommend this system for shopping mall roadshows or events inside luxury showrooms where the appearance of the equipment is just as important as the sound.

  • Small Footprint, Full Spectrum: Don't let the slim design fool you. The Curv 500PS comes with its own dedicated subwoofer. True to our philosophy at Heavy Duty AV, this ensures your event has a full audio spectrum while maintaining a minimalist, "clean" look that doesn't block your branding or products.

  • Why choose it? It provides wide horizontal coverage, ensuring your message reaches every corner of the showroom without the bulky look of traditional tripod speakers.

     

D. Line Array Systems


High-power line array speaker system flown for large-scale outdoor festivals, marathons, and esport tournaments.

When you see speakers stacked or "flown" (hanging) in a curved shape, that is a Line Array. These are designed for massive power and long-distance projection.

  • Best for: Festivals, outdoor marathons, esport tournaments, and large ballrooms.

  • Why choose it? Line arrays ensure that the person sitting in the very last row hears the exact same volume and quality as the person in the front row.
