How to Choose the Right Active Speakers to Purchase

How to Choose the Right Active Speakers to Purchase for Your Events: Technical Considerations and Use Cases

Imagine a DJ set where every beat hits you with crystal-clear precision, or a band’s performance where vocals soar and instruments shine, leaving the audience captivated. This is where having the right professional-grade active speakers makes all the difference.

What is an active speaker? Understanding Active (Powered) Speakers and Their Benefits

Active speakers, or powered speakers, are audio systems with built-in amplifiers and signal processing integrated with the speaker drivers. This design allows for custom drivers that deliver precise bass and high-frequency performance, along with digital limiters, filters, and crossovers—all in one durable enclosure.

They also usually feature a simple audio mixer built in for easy mixing of vocals and instruments, or for connecting a larger audio mixing desk with more channels into it. By combining these components, active speakers provide powerful, crystal-clear sound that reflects the engineers' intent. For users, this means easier setup and near-studio-quality audio (from a good quality active system).

At Edwards Sound Systems, New Zealand’s audio experts with over 60 years of experience, we’ll help you find the perfect Active Speakers for professional-grade sound. In this article, we’ll cover the key features of premium DAS Audio and Audiocenter powered speakers and explain why their specs matter. We’ll also recommend subwoofers for different needs—whether for DJs, AV rentals, churches, school halls, or performance venues. Let us help you find the best solution for unbeatable sound.

1. Match Power and SPL to Your Venue

The loudness and clarity of powered speakers depend on two key factors: power output (in watts) and Sound Pressure Level (SPL, in decibels). A higher SPL ensures sound reaches every corner of a venue, while RMS power (measuring continuous output) ensures distortion-free performance. Together, these factors create professional-quality audio for DJs, bands, corporate events, and venues, making music dynamic and speech clear.

When evaluating active speakers, one key specification is Rated Peak SPL @ 1m (Sound Pressure Level at one meter), measured in decibels (dB). SPL reflects how humans perceive loudness. For instance, a speaker rated at 129 dB is loud, but to sound twice as loud, it must reach about 138 dB, as a 10 dB increase is perceived as doubling in loudness. Achieving higher SPL levels requires significantly more power—every 3 dB increase requires double the amplifier power output. This demands advanced amplifier and speaker technology to deliver top-tier performance.

• DAS Audio Vantec-12A and Vantec-15A (1500W Peak, 135dB SPL): These premium powered speakers feature a 750W RMS Class D Bi-amplified system, delivering punchy bass and crisp highs through a 12” or 15” woofer and 1.4” compression driver. With high SPL, they’re ideal for medium to large venues (200–500 people) like churches, nightclubs, or performance spaces, ensuring every sound is clear. FIR filters improve phase alignment and reduce distortion for studio-quality audio.
  
  
• DAS Vantec-215A 2x15" (2250W Peak, 138dB SPL): A 3-way active speaker with a powerful 1100W RMS Class D Tri-amplified system, featuring dual 15” woofers and a 1.4” compression driver. Perfect for larger venues (300–800 people) like nightclubs, corporate events, or live performances. FIR filters and DSP ensure clear, impactful sound.
  
  
• Audiocenter 15" GT515A DSP-Controlled (1100W Peak, ~130dB SPL): A budget-friendly option with 550W RMS and a 15” woofer, delivering solid low-end for smaller venues (100–300 people) like school halls or churches. Its 24-bit DSP ensures clear vocals, though it lacks the refined clarity of Vantec speakers at higher volumes.

Subwoofer Pairing:

• For DJ or nightclub settings, pair with the DAS Audio Action-S218A (3200W Peak, 140dB SPL). Its dual 18” woofers and 1600W RMS power deliver deep bass to energise dance floors.
  
  
• For corporate events, churches, or Pro AV setups where a compact option is better, consider the Vantec 118A Active 18" Subwoofer (2000W) or the budget-friendly ACTION-S18A Active Subwoofer (1500W).
  
  
• Need more bass? The DAS Audio Event-121A (3200W Peak, 30Hz–125Hz), with its 21” woofer and 141dB SPL output, is perfect for nightclubs. However, at 85kg, it’s best for setups requiring professional transport..

Why It Matters: High SPL and RMS power ensure even the loudest sets stay clear and distortion-free, delivering professional, balanced audio that boosts the reputation of the venue, DJ, or band.

Clipping, common in low-quality speakers, happens when the amplifier can't deliver audio peaks as it is running out of capacity, causing harsh, distorted sound. If ignored, it can overheat or damage the equipment. The limit light on an active speaker is a warning, flashing to indicate that that it is being over-driven and the automatic protection is stepping in.

2. Evaluate Frequency Response for Sound Quality

Frequency response (e.g., 50Hz–20kHz) shows the range of sounds a speaker can produce, from deep bass to clear highs. A broad, balanced range is key to delivering rich, natural sound for an engaging listening experience in any setting.

• DAS Audio Altea-412A (800W Peak, 50Hz–20kHz): This budget-friendly model features Mi Series loudspeakers and a 12” woofer, delivering a wide frequency range with rich low frequencies. Its 96kHz DSP sampling fine-tunes EQ for warm, detailed sound, ideal for churches, schools, corporate events, and live music. For deeper bass without a subwoofer, consider the Vantec range.
  
  
• Audiocenter 12" DSP-Controlled (1000W Peak, ~55Hz–20kHz): With slightly less low-end, this speaker still delivers clear mids and highs via a 1.35” compression driver. DSP presets (e.g., music, speech) optimise sound for performances, making it a great choice for budget-conscious venues. A subwoofer may be needed for deeper bass.
  
  
• Subwoofer Pairing: The Audiocenter 18" DSP-Controlled Subwoofer (1000W Peak, 35Hz–150Hz) enhances low frequencies and delivers deep, powerful bass ensuring live music, organ notes and worship soundtracks resonate with power and impact.

Why It Matters: A broad frequency response delivers rich, immersive sound, enhancing music playback, DJ sets, or live performances. When basslines hit deeply and vocals are clear, the sound feels professional and high-quality.

Research shows distorted audio disrupts comfort, often subconsciously pushing people to leave. In bars, cafés, and restaurants, poor speaker quality creates an unpleasant atmosphere, driving patrons elsewhere. Clear, distortion-free audio is essential for creating a better experience and promoting customer satisfaction and loyalty.

3. Consider DSP and Connectivity for Versatility

Digital Signal Processing (DSP) and versatile connectivity, like Bluetooth and multiple inputs, allow precise sound customization and smooth audio transitions. These features adapt audio to any event and leave a strong impression. Many Audiocenter and DAS Audio speakers also feature TWS (True Wireless Stereo) Bluetooth, enabling wireless stereo by linking powered speakers. Models like the SA312+, SA315+, Vantec12A, and Vantec15A come with these advanced features.

• DAS Audio Altea Duo-10A (2000W Peak, 24-bit DSP): This 3-way column system features a 96kHz DSP with LCD interface and DASlink™ app control for EQ adjustments, perfect for live music, corporate, or performance venues. With Bluetooth streaming and mic/instrument inputs, it supports wireless playlists or live mics for smooth DJ sets or small bands. The precise DSP minimizes feedback, delivering professional-quality sound.
• Audiocenter 12" Full-Range (800W, Bluetooth): Featuring 48kHz DSP with basic presets and Bluetooth, this option is ideal for school halls or budget AV/rental gigs. While less advanced than DAS, it handles music and speech well, though its shorter Bluetooth range may limit DJ flexibility.
• Subwoofer Pairing: The DAS Audio Action-18A (1500W Peak, 35Hz–125Hz) pairs well with Audiocenter active speakers, delivering tight bass with DSP-controlled low-pass filters for corporate events or live performances.
• Audiocenter S118A: Complements the SA312+, SA315+, and GT512A speakers for AV/rental companies, with DSP-controlled low-pass filters for powerful, clean bass at events or performances.

Why It Matters: Advanced DSP prevents distortion and optimizes sound for the venue, while Bluetooth allows quick source switches. This ensures polished, seamless performances that enhance the reputation of the venue, DJ, or band.

4. Assess Portability and Build Quality

For frequent use in rentals or mobile DJ setups, portability (weight, handles) and durability (enclosure material) are key. A rugged build ensures longevity, maintaining sound quality over time, which audiences notice in consistent performances.

• DAS Audio Action-515A (1000W Peak, 45Hz–20kHz): At 26kg, this premium 15” speaker uses a birch plywood enclosure with ISO-flex paint, ideal for touring AV/rental companies or performance venues. Its M8 rigging points allow stage mounting, delivering powerful sound for bands that audiences find immersive.
• Audiocenter 15" DSP-Controlled (1000W Peak, ~27kg): Slightly heavier but with ergonomic handles, this speaker’s polypropylene cabinet suits school halls or church sound. It’s less durable than DAS but cost-effective for fixed installations where budget matters.
• Subwoofer Pairing: Consider the DAS Vantec 18A Active 18" Subwoofer, 1500W peak which is powerful but also very compact at 36kg, or the slightly larger, but more budget friendly ACTION-S18A Active Subwoofer also at 1500Wpeak – it is deep and loud and weighs 45kg.
• From Audiocenter the S3118A active sub is respectable at 2000Wpeak and weighs in at 39kg, but the DAS speakers are harder wearing and easier to transport.

Why It Matters: Durable speakers withstand wear, ensuring consistent sound quality. Lightweight models ease setup, allowing DJs or bands to focus on performance, which audiences perceive as slick and professional. They should look better and last longer on the road too.
