The RINJANI is a 2.5-way floor standing speaker kit built with top-line SATORI drivers. Each speaker is equipped with two SATORI 6.5” Papyrus cone midwoofers and the famous SATORI TW29R Ring-dome tweeter.

Mount Rinjani is a breathtakingly beautiful active volcano on the island of lombok, Indonesia. The volcano is known to display dramatic eruptions with plumes of lava and ash. The RINJANI kit is designed to deliver transparent and dynamic sound reproduction.

The RINJANI’s faceted baffle is specially designed to reduce high frequency diffraction and yields superb imaging qualities. A further 7⁰ reclined cabinet ensures time alignment resulting in sublime staging and pin point placement in instruments. The quality crossover lives in it’s own sealed chamber in the bottom of the speaker with a sharp incline to diminish standing waves.

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 RINJANI also has dual ports at the back to distribute port resonance evenly and lower compression.

For a smaller speaker with similar design goals look to the ARA and ARA Be which are the over achieving siblings of the great RINJANI.

Assembly Instructions

1. Unpack the cabinet from the packaging and take out the raw damping material from inside the cabinet.

2. Cut the raw damping material to 8 pieces of damping according to the cutting diagram.

3. Place each damping piece into the cabinet according to the position diagram. Add a bit of glue if needed to hold the damping in place.

4. Detach the pedestal by removing the four screws in each corner.

5. Place the crossover on top of the pedestal, with the orientation of the input cable towards the rear terminals and the speaker wires towards the front panel.

6. Pass the three pairs of speaker wires through each hole in the bottom panel of the cabinet.

7. Seal all the cable holes with hot melt glue.

8. Pass the input cables through the terminal hole on the rear of the cabinet, then connect to the binding posts.

9. Mount the terminal panel into the terminal hole at the rear.

10. Mount the pedestal to the cabinet using all 12 screws

11. Pull the three pairs of cables through the holes in each cabinet bracing.
