Overview

ARA, the smaller brother of RINJANI, reflecting the same design concept. The ARA is a 2-way stand mount speaker based on the excellent SATORI drivers 6.5” MW16P Papyrus cone midwoofers and the famous SATORI TW29R Ring-dome tweeter.

ARA is the highest point of Komodo Island in Indonesia and particularly notable as the habitat of the spectacular and mythical komodo dragons. The ARA kit is designed to deliver top level transparent and dynamic sound reproduction.

The ARA’s faceted baffle is specially designed to reduce high frequency diffraction and yield superb imaging qualities. A further 7⁰ reclined cabinet ensures time alignment resulting in sublime staging and pin point placement of instruments.

The cabinet is masterfully crafted from 18 mm MDF with internal bracing to distribute cabinet vibrations and lower sound coloration. Unwanted reflections are minimized by wedge shaped inner rear walls. The ARA has a large rear firing port and high quality speaker terminals on a solid aluminum binding post plate.

For a larger speaker with similar design goals look to the RINJANI and RINJANI Be which are the larger floor standing siblings of the ARA.
