Closer Acoustics OGY Active — Complete Wireless Hi-Fi System

Closer Acoustics Pure sound. Timeless design. Effortless listening. OGY Active brings the natural sound, musical coherence and distinctive acoustic design of our original OGY loudspeakers into a complete, fully integrated wireless Hi-Fi system. Combining our signature single-driver transmission-line design with dedicated amplification, custom-programmed DSP and WiSA wireless technology, OGY Active offers a new way to experience high-quality sound. Every component is designed to work together as one carefully optimized system. No separate amplifier. No speaker cables. Just music. The OGY Sound — Now Active At the heart of OGY Active is the same acoustic philosophy that defines the original OGY: one full-range driver, one carefully engineered transmission-line enclosure, and no conventional crossover. By reproducing the musical spectrum through a single driver, OGY preserves the coherence, immediacy and natural presentation that have become hallmarks of our loudspeakers. The enclosure is crafted from high-quality Baltic birch plywood, combining excellent acoustic properties with natural beauty, minimalist design and meticulous attention to detail. OGY Active preserves this original acoustic concept while introducing a completely new approach to amplification, signal processing and connectivity. A Fully Integrated System — Engineered as One Unlike conventional Hi-Fi systems, where loudspeakers and amplifiers are selected and matched separately, OGY Active is designed as a complete, self-contained electroacoustic system. Each loudspeaker incorporates a dedicated Class D amplifier and custom-programmed digital signal processing (DSP), precisely optimized for the characteristics and capabilities of its full-range driver. The amplifier and DSP work together to control the loudspeaker’s performance across its entire operating range. Maximum Performance. Built-in Protection. One of the key advantages of OGY Active is its carefully controlled maximum output. The system’s DSP programming establishes predefined operating limits, allowing the loudspeaker to reach its designed maximum sound pressure level while protecting the driver against overload and excessive distortion. This means that even at the highest available volume setting, the system operates within its engineered performance limits. 97 dB SPL at 1 metre Measured maximum sound pressure level. Rather than relying on amplifier power ratings alone, the entire system is optimized to deliver controlled, reliable performance from its compact enclosure. Exceptional Sound, Even at Low Volumes Great sound should not depend on listening at high volume. OGY Active features dynamic loudness compensation, automatically adjusting its frequency response according to the listening level. This helps preserve tonal balance, bass presence and musical engagement even when listening quietly. Whether enjoying music late at night or filling a room with sound, OGY Active adapts to the way you listen. Wireless Freedom with WiSA Technology OGY Active uses WiSA wireless audio technology to transmit digital audio directly from the Platin Stereo Hub HT to both loudspeakers. WiSA provides lossless digital audio transmission with exceptionally precise synchronization between the left and right channels. Unlike conventional wireless streaming solutions, the connection between the Hub and the loudspeakers does not depend on your home Wi-Fi router. Each loudspeaker requires only a mains power connection. All Your Music, One System The Platin Stereo Hub HT brings your music sources together in one compact, elegant device. Enjoy your favourite music through: Spotify Connect, including Spotify Lossless TIDAL Connect Qobuz Connect Apple AirPlay 2 Google Chromecast Roon Ready Bluetooth The Hub also provides HDMI ARC/eARC, USB audio, optical and coaxial digital inputs, and an analogue line input.
