Speaker Talk: Understanding dj audio terms

When hiring a DJ For your wedding or private party, you may come across terms such as, SPL, Db, Hz, subwoofers, and column arrays... tossed around. While these might sound technical, understanding these concepts can help you make more informed decisions about your event's audio setup and who you may want to hire. Let's break down some common terms and explain how they impact the sound quality and overall experience of your event.

1. SPL (Sound Pressure Level)

SPL stands for Sound Pressure Level, which is a measure of how loud a sound is. It’s measured in decibels (dB). The higher the SPL, the louder the sound.

For example:

• A normal conversation has an SPL of around 60 dB.

• A rock concert can exceed 110 dB.

For events, DJs aim to strike a balance. They want the music to be loud enough to energize the crowd but not so loud that it causes discomfort or violates local noise ordinances. High-quality DJ equipment ensures consistent sound pressure levels across the venue, so everyone experiences the same energy, whether they’re near the speakers or farther away.

2. Hz (Hertz)

Hertz (Hz) measures frequency, or the pitch of a sound. Lower frequencies create bass sounds, while higher frequencies produce treble.

• Low frequencies (20–200 Hz): These are the deep, rumbling bass sounds you feel more than hear.

• Mid frequencies (200–5,000 Hz): These are where vocals and most instruments reside.

• High frequencies (5,000–20,000 Hz): These are the crisp, high-pitched sounds like cymbals and hi-hats.

At Cascade Dreams we provide a wide variety of sound systems to ensure that your wedding or party is a night to remember.

3. Subwoofers

Subwoofers, or "subs," are specialized speakers designed to handle low frequencies (bass). They’re responsible for that chest-thumping sensation on the dance floor.

Why are subwoofers important?

• They enhance the energy of your event, especially for genres like EDM, hip-hop, or pop.

• They free up the main speakers to focus on mid and high frequencies, ensuring a cleaner overall sound.

Subwoofers come in various sizes, our team can help you select the perfect sound system for your big day!

4. Mains

“Mains” refer to the main speakers in a DJ’s audio setup. These are responsible for delivering the mid and high frequencies, such as vocals, melodies, and instruments.

Mains are typically placed on stands or pole mounted to the sub to ensure even sound coverage throughout the venue. The combination of mains and subwoofers creates a complete audio system that provides rich, immersive sound for your guests.

Why This Matters for Your Event

Understanding these terms can help you communicate your needs to your DJ and ensure they bring the right equipment for your event. For example:

• Hosting a small wedding? You might not need massive subwoofers, but you’ll want balanced sound across the room.

• Planning a big dance party? You’ll need powerful subwoofers and mains to keep the energy high.

Our team of professionals will assess your venue, guest count, and music preferences to create the perfect sound system for your event.

Audio quality can make or break an event. By understanding terms like SPL, Hz, subwoofers, and mains, you’ll be better equipped to choose a DJ that can deliver an unforgettable experience.
