S1D is a compact passive 3.5-way speaker system. It consists of folded horn-loaded 10” neodymium magnet cone driver, two side-firing reflex tuned 6.5" cone drivers, 6.5” neodymium magnet cone driver loaded with a multi-path waveguide and single 1” exit compression drivers loaded with a constant directivity waveguide.

Horn-loaded 10" driver and side-firing 6.5" drivers create cardioid polar pattern utilising patented Passive End Fire Technology. This is due to carefully matching the sound wave travel distances between side-firing drivers to the internal propagation delay of the horn sound paths. This arrangement of the two bands overlapping also increases the sound pressure level at low frequencies.

The heart of S1D is M6 mid frequency driver consisting of 6.5” neodymium magnet cone driver loaded with patented multi-path waveguide. This waveguide technology increase the sensitivity while it also helps to cancel harmonic distortion. 

HF section consists of single 1" driver mounted in constant directivity horns with multiple coverage options. High MF cut off frequency of 3kHz makes it possible to use small diaphragm lightweight compression drivers for high frequencies for increased sensitivity and HF resolution. 

S1D is powered by Aura Audio D80DSP or D100DSP powered controllers, two units per channel accordingly. Bespoke rigging and pole mount adapters enable easy and safe deployment from single unit on top of a subwoofer to a larger flown arrays.
