## Acelec Model One Passive Monitor
**Possibly the most transparent conventional loudspeaker available today.**
Over the last two years, intensive research has been dedicated to exploring new methodologies and materials. These are now incorporated in our latest product. Model One is a premium loudspeaker, offering absolute performance from the clean lines of its compact cabinet. The shape has been designed to deliver detailed and powerful sound reproduction—usually only associated with much larger loudspeakers.
### The Cabinet: Extreme Stiffness, Complete Damping
The technical criteria were quite simple: extreme stiffness using bituminized aluminium and internal damping of the cabinet to avoid any ringing effects. As a result, this approach minimizes time smearing, particularly with regard to fast and powerful transients.
This little giant speaker weighs 17kgs and is constructed with a 15 mm bituminized aluminum housing, which provides a rigid, non-resonant foundation for the drive units, ensuring that what you hear is the music, not the cabinet.
### Designed for Real Rooms
Easy placement within a normal living environment was also a design goal so that performance would not be hampered, for example, by close proximity to room boundaries (e.g., walls and corners). Furthermore, the design had to act as a simple load for a wide range of amplifiers—encompassing both delicate tubes as well as powerful solid-state powerhouses. With an efficiency of 84dB/W/m proper damping is assured, while still sounding dynamic.
### Driver Complement
- **Bass/Mid:** 15 cm Revelator transducer, renowned for its clarity, low distortion, and dynamic agility
- **Tweeter:** 18 mm Mundorf Air Motion Transformer (AMT) for lightning-fast transient response and extended airiness
The crossover frequency is set at 1.8 kHz. A dual slope strategy was employed to allow the AMT to play relatively low, seamlessly blending the two drivers for a coherent, integrated and musical presentation.
### The Listening Experience
The bottom line is simple. If your stereo lives in a smallish to medium-sized room and you hanker for the best, most accurate, most lifelike, most enjoyable sound… then Acelec Model One should be on top of your list.
It combines openness, speed, resolution, transparency and seamlessness (as with the best planars), together with the power plus dimensionality of more compact conventional systems.
Stereophile crowned our 'little' monitor speaker as recommended component for 3 years in a row. The cabinet resonance is the lowest in 20+ years of measurement history. In its price class it is a very solid performer which is hard to beat.
