What is bi-amping in an active speaker?

Bi-amping means two separate amplifiers inside one cabinet: one for LF, another for HF. Each is optimized for its frequency band. Result: lower distortion, higher SPL, more accurate sound. Top models feature three amplifiers (tri-amping) for LF, MF, and HF.

Do I need a powered subwoofer?

For speech and background music — no, full-range tops are sufficient. For live music, DJ, and club events — yes: a subwoofer adds depth at 30–60 Hz that 10–15-inch tops cannot fully reproduce. Typical ratio: 1 subwoofer per 1–2 tops.

Can I connect multiple active speakers together?

Yes — via link/thru output (XLR), DSP network (Dante, AVB), or daisy-chain. Most active PA speakers have an XLR link out. Column arrays connect in stacks. DSP-enabled models allow remote control of every speaker from a laptop or tablet.

Q: What is the difference between active and passive speakers?

An active speaker has a built-in amplifier (one or more), DSP processor, and crossover. You only need a signal cable and a power outlet — no external amplifier required. A passive speaker needs a separate power amplifier and speaker cables.

Q: What types of active speakers exist?

Portable PA (battery or mains), column/line arrays, full-range tops, active stage monitors, powered subwoofers, installation speakers (ceiling/wall with 70V/100V transformer), multimedia speakers with Bluetooth/Wi-Fi.

Q: How much power do I need?

Roughly: 50–100 people indoors — 300–500 W per channel. 200–500 people — 500–1,000 W. Outdoor 500+ — 2,000 W and above. Consider both peak and RMS power: RMS is continuous, peak is for short transients.

Active speakers are loudspeakers with a built-in power amplifier, DSP processor, and crossover. Connect your signal, plug into mains — sound is ready. No external amplifiers, no cable matching, no impedance calculations. Portable PA, column arrays, stage monitors, powered subwoofers, installation solutions. SoundsGood offers active speakers for any scenario — from an intimate event to a stadium concert.

🔊 Active Speakers: What They Are & Who Needs Them

An active (powered) speaker is a loudspeaker with a built-in power amplifier (often multiple), electronic crossover, and DSP processor. You feed a line-level signal (from a mixer, player, or microphone) — the speaker handles the rest: amplifies, splits into bands, limits, and equalizes. The result — less gear, faster setup, optimized sound right out of the box.

🎤 Concerts & Events

Live performances, corporate events, conferences, festivals. From intimate evenings for 30 guests to open-air stages for thousands. Quick setup — arrive, place, connect XLR, power on. No rack amplifier, no speaker cables running across the floor.

🏢 Business & Installations

Restaurants, bars, retail, offices, conference rooms, houses of worship, lecture halls. Background music, speech reinforcement, presentations. Installation-grade active speakers with 70V/100V — dozens of speakers on a single line, DSP control from a laptop.

🎧 DJs & Clubs

DJ sets, dance floors, bars. Active tops + powered subwoofers — powerful, deep sound without a rack of amplifiers. DSP control of delays, limiters, crossover. Cardioid subwoofers for directional bass.

⚡ Active Speaker Technology

🔌 Class D Amplifiers

The modern standard — Class D (switching): 85–95% efficiency (vs. 50–65% for Class AB). Less heat, less weight, more power for the same size. A 2,000 W amp weighs 2–3 kg instead of 15 kg. Class D is what made active speakers light and powerful.

🧠 DSP (Digital Signal Processing)

The speaker's digital brain: EQ, crossover, limiter, delay, phase alignment — all in the digital domain. Presets for different scenarios (speech, music, monitor, outdoor). Overload protection. Some DSPs feature FIR filters for linear phase and ideal impulse response.

🔀 Bi-amping / Tri-amping

Each frequency band (LF, HF or LF, MF, HF) gets its own amplifier. An active electronic crossover splits the signal before amplification — more precise than passive. Lower intermodulation distortion. Higher headroom. Each amp is optimized for its driver.

🌐 Networked Audio (Dante / AVB)

Digital audio over Ethernet: Dante, AES67, AVB, Milan. One Cat6 cable replaces dozens of analogue XLRs. Route any input → any output. Monitor every speaker from a laptop. Ideal for installations and large systems.

📶 Wireless Features

📱 Bluetooth

Most modern active speakers include Bluetooth 5.x for streaming audio from a phone or tablet. Ideal for background music, set breaks, presentations. Codecs: SBC, AAC, aptX. Range: up to 10–30 m. Does not replace wired connections for critical performances (20–40 ms latency).

📡 Wi-Fi / App Control

DSP management via Wi-Fi or Ethernet from a dedicated app. Adjust EQ, volume, delay, presets — from your phone. Monitor status (temperature, load). Firmware updates. Multiple speakers — one control panel.

🔋 Battery-Powered Models

Portable active speakers with a built-in Li-Ion battery. 4–12 hours of operation without mains. For street musicians, outdoor events, fitness classes, countryside weddings. Some include a solar panel for charging. Power: 100–500 W.

⚖️ Active vs Passive: Which to Choose

✅ Active Advantages

All-in-one — no external amplifier needed. Faster setup. DSP optimization out of the box. Overload protection. Fewer cables. Bi-amping. Guaranteed amp-to-driver matching. Easier to transport (one cabinet instead of two).

⚠️ Active Limitations

Heavier than passive (built-in amp). Requires a power outlet at each speaker. More expensive (amp included in price). If the amp fails — the speaker is silent (a passive can be connected to another amp). Less flexibility in amp choice.

🎯 When to Choose Active

Mobile musicians and DJs (fast setup). Rental companies (simplicity). Installations without a separate equipment rack. When you need DSP in every speaker (individual EQ, delay). When minimal gear count matters.
