Rinjani Be
A 2½-way floorstander built around the Satori TW29BN beryllium tweeter and dual 6½" Egyptian Papyrus midwoofers. The cabinet is tilted 7 degrees for time alignment, with faceted top edges and slanted internal partitions.
2½-way floorstanding speaker with Satori® Beryllium tweeters
Named after Indonesia's second-largest active volcano. Erupts accordingly.
The Rinjani Be is what happens when SB Acoustics’ Danish engineering team designs a compact floorstander with no committee and no cost-cutting. Two 6½″ Satori MW16P Egyptian Papyrus midwoofers per cabinet cover midbass through the upper midrange, then hand over at 2300 Hz to a 29 mm Satori TW29BN beryllium dome — the same tweeter the three-way Sasandu uses.
The cabinet is tilted 7 degrees because the Danes are obsessed with time alignment. The faceted top edges reduce diffraction because they're also obsessed with imaging. The internal partitions are angled to kill standing waves because apparently they're obsessed with everything.
What's Inside
Tweeter — Satori TW29BN beryllium dome. The published datasheet gives Fs 700 Hz, 95 dB at 2.83 V/1 m, Qts 0.46, Bl 3.1 Tm and 80 W rated power. Dual balanced compression chambers, dual copper caps, CCAW voice coil, high-saturation neodymium motor.
Midwoofers — Dual Satori MW16P-8, 6½" Egyptian Papyrus cones. SB's proprietary natural-fibre blend, manufactured in-house. Each midwoofer sits in its own isolated chamber to prevent acoustic crosstalk. Low damping rubber surrounds for transient speed.
Cabinet — 18mm MDF with internal bracing. Slanted baffle for time coherence. Non-parallel internal walls. Generous damping material. Rear-firing bass reflex port tuned to 35.5 Hz. Piano gloss finish that your house guests will compliment before they hear a note.
Crossover — 2300 Hz, pre-assembled and tested. Connectors only go one way. Gold-plated WBT-style binding posts because details matter.

Reviews
"I struggle to think of a floorstander anywhere near this price point offering a mix of such high quality drivers and which is built to this level of integrity and finish. Add to that, most importantly, the fact that Rinjani BE performs, presenting music to very high standards. Think towards double its value and you’d be in the ball park.
Mount Rinjani is the second largest active volcano in Indonesia. As a fitting reflection of the sheer might of a volcanic event, the SB Acoustics Rinjani BE is a force-of-nature erupting on to the quality loudspeaker space. Yes, I’m convinced the Rinjani BE is a compelling, genuine high-end audio bargain." -

Schematics
Open it up and you’ll see where the money went. Isolated chambers for each midwoofer and the tweeter. Slanted internal partitions. Angular baffle. Every surface angle calculated to reduce colouration and reflections. This is what engineering looks like when the people designing it actually listen to music.
Come listen. Bring your favourite tracks. Bring your scepticism. Leave with neither.
SB Acoustics was formed to bring an alternative to the high-end transducer market.

The cabinets arrive finished
Every cabinet in the photographs on this page is what turns up on the pallet. They are cut, assembled and finished at the same works that makes the drivers, on the same machines, to the same tolerances — so the job in front of you is the acoustics: mount the drivers, wire the crossover, fit the damping.
Six finishes are drawn up for the Rinjani Be: white satin, white high gloss, black satin, black high gloss, red high gloss and orange high gloss. Magnetic grilles are part of the set, and the set covers two cabinets.
Tell us which finish you want when you enquire and we will confirm it against the current factory list before anything is ordered.
