The ORA4 speakers are designed for those who demand precision and detail, delivering professional-grade sound across a flat, full-range frequency response. Powered by 140W of DSP-tuned, bi-amplified Class-D amplification, they provide accurate, balanced audio for both studio monitoring and Hi-Fi listening. The 4 woofers produce deep, punchy bass, while the overall tuning ensures your music or mixes are heard exactly as intended, making them an excellent choice for creators and audiophiles alike.
Versatility is at the core of the ORA4s design, offering multiple input options to suit a wide range of devices. USB-C delivers a direct, lossless connection to PC or Mac for high-quality audio playback, while Bluetooth 5.0 allows seamless wireless streaming from smartphones and smart home devices. An RCA input is also included for connecting analogue equipment such as turntables or legacy audio gear, ensuring compatibility with both modern and classic setups.
For enhanced low-frequency performance, the ORA4 features seamless subwoofer integration. When a subwoofer is connected, an automatic crossover redirects frequencies below 80Hz, allowing the speakers to focus on midrange and high frequencies. This improves clarity, reduces distortion, and delivers a more powerful and immersive listening experience, ideal for both music production and cinematic audio.
Despite their powerful performance, the ORA4 speakers maintain a compact and flexible design. Their small footprint makes them perfect for desktop setups or stand mounting, while threaded inserts on the rear and base provide multiple positioning options. Additionally, magnetic shielding allows safe placement near CRT or PVM displays without interference, making them a great choice for retro gaming setups or specialised studio environments.
