THE HALO 10 PRO Active Ext Cardioid
Ascendo THE HALO 10 PRO Active Ext Cardioid Screen Speaker
ASCENDO's flagship statement screen channel speaker. The HALO 10 PRO features a circular cardioid array of six 8-inch woofers and a 10" coaxial point source midrange, delivering 136+ dB with near-zero back energy. Designed for high-end private cinemas where absolute sonic immersion is paramount.
Overview
The ASCENDO HALO 10 PRO is a fully active 3-way screen speaker engineered for reference-grade private cinema installations. At its core is a 10" point source coaxial driver combining a midrange cone with a 3" compression driver on a short horn, surrounded by a circular array of six 8" cardioid woofers that suppress rear energy by design. This extended cardioid low-frequency array eliminates the back-wall reflection problem that plagues conventional LCR speakers behind acoustically transparent screens, resulting in dramatically cleaner bass imaging and reduced room mode excitation. The HALO 10 PRO is entirely self-powered, requiring only signal and mains: HF amplification at 600–1200W, midrange at 2000–2500W, and LF at 2000–5000W depending on configuration. The finish is high-gloss forged carbon fibre. Mounting is via French cleat wall brackets with 0–15° angular adjustment, plus VESA 200x200 compatibility.

Integrating the Ascendo HALO 10 PRO for Reference Screen Channels
At Kolosseum, the HALO 10 PRO represents the pinnacle of screen channel performance for private cinema. We specify this speaker in rooms where maximising sonic impact, minimising screen reflection artefacts, and delivering a truly cinematic SPL headroom are the brief. Its cardioid behaviour is a genuine acoustic advantage in rooms where the screen is close to the rear wall.
Room Requirements
The HALO 10 PRO demands solid structural mounting given its 47 kg weight. French cleat systems must be fixed to load-bearing or reinforced wall structures. The speaker is best positioned fully behind an acoustically transparent screen, and we account for its depth and angular adjustment range in the acoustic design.
Recommended Screen Pairing
Works behind any high-quality acoustically transparent screen fabric. The coaxial point source and cardioid bass array are particularly effective behind microperforated screens where HF transmission is consistent across the surface.
Acoustic Considerations
The extended cardioid array substantially reduces rear-wall energy below 200 Hz, which can reduce the need for heavy bass treatment behind the screen. We measure and verify cardioid performance during commissioning to confirm room integration.
Frequently Asked Questions About the Ascendo THE HALO 10 PRO Active Ext Cardioid Screen Speaker.
The six-woofer extended cardioid array is the key differentiator. It radiates bass primarily forward and suppresses rear energy, dramatically reducing screen-wall reflections and room mode interaction that conventional speakers cannot address.
No. It is fully active with built-in amplification across all three ways. You supply balanced audio signal and mains power. No external amplifier is required.
It can be used as a centre-only, but for optimal timbre matching and spatial coherence across the soundstage, Ascendo recommends matching all three LCR positions. Kolosseum can advise on mixed-model configurations where budget constraints apply.
The HALO 10 PRO works behind any acoustically transparent screen. Microperforated screens with consistent HF transmission are the ideal pairing for a coaxial point source at this performance level.
