Ex Machina Arcturus is the flagship three-way studio monitor engineered for flush-mount (soffit) mains applications or as a towering freestanding system in world-class control rooms. Expanding upon the proven coaxial and axisymmetric architecture of the Quasar, the Arcturus introduces a devastatingly accurate low-frequency section featuring twin 10.5-inch SEAS Extreme neodymium subwoofers. By offloading the massive Hypex Ncore amplification and SHARC+ DSP processing into a dedicated 2RU external rack pack, the system ensures optimal thermal management while maximizing internal cabinet volume for pure acoustic efficiency.

Unrelenting Headroom Without Port Noise

Monitoring sub-bass in modern production requires deep, visceral output without sacrificing transient speed. The Arcturus utilizes dual 10.5-inch SEAS subwoofers driven by a unique split-gap twin-ring radial neodymium motor. This topology guarantees phenomenal motor strength and linear excursion, yielding vanishingly low THD even at continuous output levels of 117dB. Rather than relying on ported designs that inherently introduce group delay and port turbulence, the Arcturus employs completely sealed enclosures crafted from dense, heavily damped Valchromat. The cabinet is reinforced by an ultra-rigid 38mm (1.5-inch) laminated front baffle, ensuring the enclosure remains acoustically inert and transient responses stay surgically tight down to an 18Hz cutoff.

Point-Source Accuracy and DSP Linearity

Exacting spatial localization is non-negotiable for critical mixing and mastering. The mid and high frequencies are handled by a custom SEAS 7-inch coaxial driver outfitted with ultralight, resonance-suppressing Metamodal TX carbon fabrics. The remote 2RU pack leverages flagship AKM Velvet Sound conversion and 5th-generation SHARC+ DSP to govern the entire system. This powerful hardware calculates 4th-order crossovers natively with full phase correction, delivering an astounding ±15° linear phase response from 20Hz to 30kHz. Combined with a mathematically optimal waveguide providing a symmetrical 90-degree conical dispersion, the Arcturus creates a massive, razor-sharp sweet spot.
