Quantum 1003

Apraksts

Woofer and midrange:
- Well-ventilated die-cast basket to prevent turbulence and compression effects
- Magnetic circuits with double induction rings for optimized stray-field and distortion properties
- Controlled Flexing Cone: New cone geometry for controlled projection of wave fronts in the mid range, and with if the capability to reproduce a greater bandwidth
- 16 and 20cm woofers with particularly flat cone profile and an addapted dust cap for enhanced all round dispersion and better synchronization with the mid-tweeter range

Tweeter:
- f-max Signature tweeter dome with a particularly wide surround for optimized  dispersion characteristics at frequencies above 20kHz
- Solid aluminium front panel with short horn for optimum joining to the case and to reduce resonance problems
- Domes made from a precision fabric, hand-coated with ceramic particles
- Copper cap in the magnet system for low distortion
- Magnet system having extensive ventilation and low self-resonanse
- Double front ventilation to prevent voice-coil symmetry from being negatively impacted at high levels

Crossover:
- Built to 24dB LKR topology standarts with transformer core coils and audiophile polypropylene capacitators. XO on 2 seperate circuit boards in order to optimize the speakers when they are used in bi-wiring mode.
- XO mechanically insulated from the cabinet

Cabinet:
- Double sectioned side reinforcements with varying material thickness to reduce vibration in the cabinet
- Cabinet top in double-sectioned sandwich construction
- Extensive bracing to support the chassis unit
- Seperate tweeter housing
- High-quality high gloss varnish
- Solid MDF cabinet with low-resonanse baffle and real wood veneer

Highlights:
- Sophisticated voice-coil ventilation for high efficiency
- High-quality interior cabling by OEHLBACH
- Airflex ports with generously dimensioned opening for optimum bass loading
- Detachable cloth grille with opimized acoustic transmissivity
- Large aluminium die-cast terminal panel with solid screw terminals
- Bi-wiring/Bi-amping option
- Gold plated and acrylic-encased speaker connectors
