Audio Pro SP-3 Wireless Active Loudspeaker
The Audio Pro SP-3 is a professional active wireless loudspeaker designed to provide high-quality background audio in commercial and public spaces. Combining a compact Scandinavian design with DSP-controlled amplification and reliable 1.9 GHz wireless transmission, it delivers clear, balanced sound without complicated installation or extensive cabling.
SP-3 is particularly well suited to retail stores, cafés, restaurants, hotels, offices, showrooms and other commercial interiors where discreet, flexible audio distribution is required. The speaker is designed for installation in compatible three-phase lighting track systems, allowing it to become part of the existing ceiling infrastructure while keeping the installation visually clean. An optional wall-mount solution is also available for installations where a lighting track is not suitable.
At the heart of the SP-3 is a digital Class D amplifier delivering 2 × 25 W. The amplifier works together with a 4.5-inch woofer and a 0.75-inch soft-dome tweeter in a two-way bass reflex enclosure. Digital signal processing helps optimize the speaker's acoustic performance, while the 60–22,000 Hz frequency range allows it to reproduce both detailed high frequencies and a solid, controlled low end.
The proprietary wireless system operates on the 1.9 GHz RF band rather than conventional Wi-Fi frequencies. This helps minimize interference and unwanted delays, which is especially important when several speakers are used throughout a commercial space. Depending on the installation conditions, the wireless transmission range can reach up to 100 meters. The system supports plug-and-play operation without requiring dedicated software and can work with Mac/PC and analogue audio sources.
The SP-3 can also be integrated into a wired audio setup, giving installers greater freedom when designing or expanding a commercial sound system. Its compact 155 × 155 × 240 mm enclosure and approximately 2.1 kg weight make it easy to position without visually overwhelming the interior. The minimalist Scandinavian styling is available in several colour options, allowing the speaker to blend naturally with different interior concepts.
