Portable Array Speaker Subwoofer Combo | USB Bluetooth PA Speaker System & Compact Stage Audio Speaker Kit

We are NingBo FengSound Electronic Co.,Ltd., a professional manufacturer dedicated to professional PA audio systems. Event planners and mobile DJs often struggle with bulky sound rigs that require complex wiring and separate signal processors. Heavy traditional Speaker stacks cost time on installation and transportation, limiting flexibility for mobile performances and multi-venue activities.

To simplify on-site audio setup and deliver full-range sound reinforcement, we developed our S Series Satellites P.A. Systems for diverse event scales. Designed for quick deployment and full frequency playback, our integrated Portable Array Speaker Subwoofer Combo balances deep bass and clear vocal reproduction. Built with versatile media playback functions, our multi-source USB Bluetooth PA Speaker System allows seamless pairing with different audio devices. Packaged into a space-saving assembly, our practical Compact Stage Audio Speaker Kit suits small gatherings as well as large commercial occasions.

We also carry matching audio equipment including Portable Satellite PA System, accurate Powered Studio Monitors and durable Wooden Enclosure Speakers for one-stop audio procurement.

MDF Cabinet & Adjustable Mounting Structure

Our S0815AD satellite speaker set uses thick MDF wooden cabinets coated with texture paint. This material suppresses cabinet resonance and unwanted vibration, delivering cleaner low-frequency response compared with all-plastic speaker housings. The S series adopts high strength engineering plastic for auxiliary structural parts to enhance impact resistance during repeated transport.

The dual stand hole design enables 10° angle adjustment for satellite units. Users can tilt the satellite array to direct sound coverage toward audiences freely, optimizing sound distribution in different venue heights and space layouts. This flexible mounting design greatly improves sound uniformity across listening zones.

Built-In DSP Digital Audio Processing

The built-in high-performance DSP chip is the core tuning unit of this satellite PA system. It integrates limiter, compressor, crossover and parametric equalizer modules. With 4 preset speaker operation modes, users can switch quickly according to event types without extra external processors.

The limiter function prevents audio clipping and protects drivers from overload damage. The compressor balances dynamic range for vocals and live music, while crossover separates low, mid and high frequency signals properly, letting subwoofer and satellite array work independently without signal interference.

Multiple Input Options & Wireless Connection

This audio system supports multiple audio input methods. Apart from balanced and unbalanced line inputs, it is fitted with a digital media player supporting USB and SD card playback. The embedded Bluetooth 4.2 stereo module realizes simple wireless pairing with mobile phones, laptops and tablets, saving cable arrangement time at events.

Combined with XLR combo jack and RCA wired ports, it supports microphones, musical instruments and other professional audio sources. Operators can switch between wired and wireless sources flexibly to meet the demands of live shows, speeches and background music playback.

Multi-Layer Safety Protection & Heat Dissipation

We build comprehensive protection circuits inside the amplifier module. Short-circuit, over-current, over-temperature and soft-start protection keep the whole system stable during continuous high-power work. Variable-speed cooling fans adjust rotation speed automatically based on working temperature, avoiding overheating during long-hour operation.

Front panel control knobs include left/right volume, subwoofer volume, DSP mode and 180-degree phase reverse switch. Clear indicator lights display power status, input signal, limiter activation and Bluetooth connection for convenient on-site inspection.
