Ultimate AIR Loudspeakers

Lifelike Immediacy
SAKURA is our second and ultimate A.I.R loudspeaker system. With A.I.R. the enclosure disappears, and with it, box sound and coloration associated with traditional loudspeakers.

A.I.R is derived from the well-known dipole model. With a radiation pattern in the form of an eight and the removal of the box, it eliminates side walls reflections and enclosure resonances. At Eden Acoustics we were looking for the best of what a dipole loudspeaker could offer, while refining the sound, in a more modest size and with improved looks. After multiple tests and measurements, we removed the baffle and added a sophisticated digital processing system, which resulted in a livelier, more holographic sound.

SAKURA pushes the limits by removing the TÔMEI centre bass module and installing one bass driver in each tower. Two new 6inch (156mm) mid-bass units are installed in each tower. These modifications improve the dynamics, lower distortion, and result in blindingly fast reproduction of sound, with faster, deeper bass rendition.

SAKURA systems are available in two formats. Base version is comprised of two 3-way SAKURA towers, with a remote control-based central control unit (CCU). The second version called SAKURA
2 sports two mid drivers on each side. Optionally, SAKURA systems can come as ROON™ ready with network music streaming capabilities.

Holographic Acoustics
SAKURA is a 3-way A.I.R. loudspeaker using 3 or 4 drivers:
  • One or two sliced cone 156mm (6-inch) mid/bass driver featuring an extremely large linear excursion (13mm - 0.5inch),
  • One neodymium dome tweeter sporting a two part aluminium faceplate with mechanical decoupling,
  • One long-throw, one-inch linear excursion, thirteen-inch (34cm) bass driver to reproduce the lowest registers of bass with incomparable speed and accuracy.

The tweeter has been chosen for its fatigue-free listenability and outstanding sonic transparency. Both mid-bass and bass drivers offer extreme linear cone excursion to sustain the high demands of the A.I.R. architecture.

All drivers are perfectly integrated in time and phase, with no baffle to restrict high and mid frequency dispersion. The result is an incredibly airy and large soundstage that seems to float into the room. Some call it holographic acoustics and indeed SAKURA gives that feeling of really being at the concert or in the studio with the artist.

Digitally optimized
SAKURA’s central control unit comes with first-class components from Hypex, Analog Devices, XMOS and AKM.

A new Analog Devices SHARC DSP called Nexus is used to optimize each driver’s amplitude, impulse, time and phase response. New features include a Raspberry PI4, The RPi4 is directly connected to the DSP through its I2S interface. It can send streams to the DSP like a music server. It can also receive streams like a measurement system. Other features include Bluetooth APTx-HD, Headphone Amplifier, improved DAC modules, Phantom power microphone input with internal measurement system.

Hypex NCORE™ amplifiers are directly connected to each drivers’ voice coils. Without any power-robbing, phase-shifting, passive crossover parts in the signal path, SAKURA delivers blindingly fast sound reproduction and lifelike immediacy.

The CCU accepts connections through balanced/unbalanced analog, S/PDIF coax IN and OUT, USB Class 2, and with the optional Network Music Server (NMS), streaming through Airplay, UPnP/DLNA, Bluetooth and ROON™.
