Eos HX: Concentrated state of the art
Application(s). Time-coherent 2-way speaker sounds best on stands or a bookshelf.
User adjustability (Soundfield Convergence™). Tweeter adjusts front-to-rear in its channel via easy-to-use thumb-nut.
Room size. Small to medium, 100-500sf.
Power (amplifier’s 8 ohm rating). 7 to 150 Watts.
Response. In-room, typically +/- 2dB from 50Hz to 20kHz; - 3dB frequencies below 47Hz and above 26kHz. 20 to 24-inch high speaker stands recommended.
Distortion. <0.5% harmonic 100Hz-12kHz, <1% intermodulation, both at 98dB at 1m (I.M.D. is for any two frequencies separated by a 10:1 ratio.)
Phase shift. +/- 2 degrees acoustically, from 200Hz to 8.5kHz for Eos HD. Does not vary with loudness. For Eos HX, spec is +/- 2 degrees acoustically, from 50Hz to 10kHz.
Rise time. <10 microseconds, positive or negative input. Does not vary with loudness.
Polarity. Positive, over full bandwidth.
Dispersion. Omni at 47Hz, smoothly decreasing to cardioid at 12kHz.
Impedance. 4.8 Ohms, +/- 0.75 Ohms 100Hz to 20kHz. Does not vary with loudness.
Sensitivity. 90dB for 2.83V at 1m, at sea level. Dynamically linear within 0.5dB to 100dB.
Max SPL. 105dB peak at 3m from stereo pair, first-arrival (without room gain).
Pair matching. Amplitude +/- 0.25dB; impedance +/- 0.15 Ohms, 160Hz-8kHz; crossover parts +/- .15%.
Cabinet finish and choices. Clad in black Texture-Kote™ for the look of pin-grained leather. Cocobolo or Bolivian rosewood (depending on availability) trims the top channel. Other trim choices can be quoted.
Speaker Conditioning. Upon request, we will gladly condition the speakers' drivers before shipment at no additional charge.
Grilles. Speakers have been designed for foam grilles to be left in place.
Accessories. Ownership Guide.
Size. 19.875"H; 8.8"W 12.625"D. For speaker stands, base: 7"W, 10.875"D.
Weight. 45lbs. (20.5kg) each.
Woofer diameter. 6" (17cm).
Woofer construction. Single-pressed paper/carbon fiber cone with ultra-linear suspension, vented under-hung 2-layer, 1" (25mm) voice coil wound on Kapton former. Mechanically damped chassis. Shielded, radially-magnetized, neodymium-iron-boron magnet structure with heat dissipating black coating; 0.32" (8mm) p-p linear excursion; 9.85g moving mass.
Woofer cabinet. Woofer mounted in Q-Stone™ cabinet. 4th-order Butterworth ported with nearly zero box loss.
Woofer / Bass port. Twin 1.625" (41mm) aerodynamic ports tuned to 54Hz merge to become one port inside. The Bi-Port™ intake opening more efficiently transmits bass pressures from its ideal placement inside the enclosure and optimizes bass delivery into the room via larger-than-usual twin openings on the front.
Tweeter diameter. 1.06" (27mm).
Tweeter construction. Lightweight, impregnated fabric dome with high-compliance polymer suspension. Ferrofluid-cooled voice coil with highly-flexible lead-in wires. Fully vented into large, damped rear chamber, with extruded heat sinks. 0.31g moving mass. Neodymium ring magnet.
Tweeter enclosure. In non-defractive, Q-Stone™ enclosure with integrated tweeter chassis damping.
Wiring. Exclusive, High-Definition CopperMatrix™ wire by Marigo Audio Labs: 18-gauge, 650+ strands of Litz wires; oxygen-free, six-nines purity, single crystal copper; proprietary multiple-layered winding geometry; double cryogenically-treated; organic dielectric insulation; proprietary internal vibration damping system (Pure metals love to ring both sideways and along their lengths. Marigo CopperMatrix™ wires do not and cannot ring, which sounds like noise).
Crossover. Balanced-Phase™ first-order circuit with XTC™ technology.
Zobel circuit's capacitor. Woofer: Ultra-premium quality. Tweeter: Ultra-premium quality.
Crossover principal capacitor. Woofer: N/A. Tweeter: Ultra-premium quality.
Crossover bypass capacitor. Woofer: N/A. Tweeter: Ultra-premium quality.
Binding posts. Made by Vampire Wire of pure oxygen-free copper, directly gold plated. Mounted on the back.
