overview

The SASANDU is a large 3-way floor standing speaker showcasing the advanced SATORI 29mm Neodymium Beryllium tweeter. The midrange is covered by the 6½” SATORI MR16P-4 Egyptian Papyrus cone midrange with a dedicated large sealed midrange chamber for low compression and wonderful open midrange reproduction. Each speaker is solidly anchored in the lower octaves by two 7½” SATORI MW19P-8 for a deep, tight, and satisfyingly musical bass.

SASANDU also called Sasando means “sounded instrument” and is a traditional Indonesian harp like string instrument with a body made from bamboo and native type of leaves. The SASANDU is a no compromise speaker kit designed to reproduce music as faithfully as possible.

The SASANDU’s faceted baffle and optimized tweeter position to lower diffraction as well as inclined cabinet to time align the drivers result in state of the art imaging. The large high quality crossover has it’s own chamber behind the removable plinth.

The cabinet is masterfully crafted from 28, 18, and 15 mm MDF with strategic internal bracing to distribute cabinet vibrations and lower sound coloration. A slanted internal partition reduces internal standing waves and the over sized 75 mm port at the rear ensures uncompressed bass even at very high listening levels.
