Aslan Acoustics Austral

Project 'Austral' is the first in the signature series of products. The design brief was simple... produce the best value for money ultra high-end speaker available. Aslan Acoustics has achieved this aim on virtually every level with this loudspeaker.

Austral's initial design brief was to develop a superlative full range speaker, capable of high SPL's and with as flat a frequency response as possible. In order to achieve this aim, their Pro-12 subwoofer design has been modified from a bass reflex enclosure to a larger 103 litre tapered transmission line tunnel which wraps around a specially designed 5 speaker, three-way vertical D'Appolito array for pinpoint voicing and accuracy. The D'Appolito array consists of twin butyl rubber impregnated carbon fibre mid-woofers, twin silk dome midrange-tweeters and a single ribbon super tweeter. The dual chamber cabinet design takes the form of a truncated pyramid in order to eliminate internal standing waves and provide an aesthetically appealing form. The subwoofer chamber is a constant taper "C" shaped design, wrapping around the inner chamber which is asymmetrical and has no parallel surfaces. 

The ribbon tweeter is exactly at ear level from a seated position for perfect acoustic image centering whilst the combination of cone and dome midranges provide excellent off axis response up to 35°. Both tuning ports exit at the top of the cabinet to provide bass reinforcement for the lower driver in the same vertical plane as the array. Testing has confirmed that the point source appears to emanate from a position approximately 300mm in front of the tweeter making it impossible to localise the sound source to any particular driver.

The crossover circuit for the centre array is a three-way 12dB per octave design incorporating separate filters for each driver. This design utilises the finest Mundorf components exclusively and is hard-wired. High grade OFC wire is used throughout. The Austral has a raw frequency response of 25Hz to 35kHz ±2.5dB with 20Hz only a further 2dB down. With 1/3rd octave smoothing applied the response becomes an incredibly linear 23Hz - 35kHz ±1.5dB making Austral one of the most accurate speaker systems available today.;

Each pair of Austral’s are individually signed and numbered and incorporate matched driver pairs and crossover components to provide a pin-point accurate sound stage and are hand assembled to order for our clients.
