Sasandu

A three-way floorstander built around the Satori® Beryllium TW29BN tweeter and Satori® Egyptian Papyrus midrange and woofers. The inclined cabinet is designed for time alignment, the faceted baffle and tweeter position for reduced diffraction, and the midrange sits in its own sealed chamber.

3-way floor-standing speaker with Satori® Beryllium tweeters and dual Satori® Egyptian Papyrus drivers.

The Sasandu is a three-way floorstander built around Satori’s Egyptian Papyrus cones and a beryllium dome. Per cabinet: two 7½″ MW19P midwoofers, a 6½″ MR16P midrange and a 29 mm TW29BN beryllium tweeter, every one of them on a neodymium motor in a cast aluminium chassis.

Reviews

"I would have thought that the SASANDU would just multiply my experience with the Ara BE tenfold. This is not the case as the SASANDU carries its own sound signature albeit using similar drivers as Ara BE. The whole cabinet design somehow gave a different perspective and listening experience to me in my system. "

Schematics

A slanted baffle for time coherence, and a separate internal chamber that keeps the midrange sealed away from the bass. Six cabinet finishes — satin or high gloss in white and black, high gloss in red or orange — and magnetic grilles come with them.

Tweeter — One Satori TW29BN-B-8 per cabinet

A 29 mm beryllium dome on a high-saturation neodymium motor with a T-shaped pole piece. SB Acoustics’ own summary of why beryllium: “beryllium dome for non-resonant high frequency extension”.

The engineering around the dome is where the rest of the money goes — a two-part aluminium faceplate with mechanical decoupling built in, dual balanced compression chambers behind the dome, dual copper caps in the gap to hold inductance down, a CCAW voice coil for low moving mass, and silver lead wires.

Midrange — One 6.5″ Satori MR16P-4 per cabinet

The same Papyrus cone material as the woofers below it, on a 35.5 mm coil and a neodymium motor, but drawn for the band that carries voices and given its own sealed chamber in the cabinet.

A 39 mm voice coil under a black Egyptian Papyrus cone, on a neodymium motor and a cast aluminium chassis. Papyrus is SB Acoustics’ own natural-fibre cone material, pressed in-house at Surabaya, and it is what gives the cone its speckled surface.

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 Sasandu: 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.
