Aslan Acoustics R1

The new Reference R1 system embodies everything Aslan Acoustics has learnt over 30 years of designing and developing loudspeaker systems.

The R1 is a 4-way, full frequency range system featuring the latest in both digital and analogue technologies in a system capable of replicating the impact of a full symphony orchestra in all its power and detail. With 3.2 kilowatts RMS of on-board amplification, laptop programmable filters and equalisation, this system will astound.

The Reference R1 is the benchmark for Australian audio design. Each cabinet employs a 15" subwoofer in a sealed chamber fed by a 1,000 Watt RMS digital amplifier with parametric equalisation and remote control.

Above this is a 5 driver D'Appolito array featuring twin 10" carbon fibre woofers, twin 6.5" Kevlar midranges, and Mundorf's AMT 2440 Air Motion Transformer. This group of drivers are fed by a bank of class AB solid state amplifiers with 600 Watts RMS available. Each woofer has a dedicated 150 Watt amplifier, whilst the high efficiency midranges share one and the tweeter has its own unit.

The digital crossover and equalisation circuits feature 24bit, 96kHz Burr Brown DAC's and ADC's, 48 biquads of processing filters, 14 parametric equalisation filters per driver, crossover slopes up to 48db per Octave and adjustable gain and delay for each driver.

Each cabinet is a three layer construction with the inner chassis encased in a layer of solid hardwood. Every driver has its own dedicated enclosure and the on-board amplification also resides in separate acoustically isolated and vented chambers. Depending on choice of hardwood finish weight per cabinet is in the region of 275-300 kilograms.

The system is installed and programmed 'in room' to adjust for room modes and obtain a flat frequency response. Aslan Acoustics recommends that owners have their electrician install a dedicated 10 amp circuit for each speaker.
