Signature Series
Sony expertise in precision-engineered powered speakers

The SA-Z1 brings together Sony’s legendary audio expertise, with first-of-its-kind custom componentry and benchmark audio technologies. Thanks to a trio of accumulated acoustic, electronic, and signal processing technology, SA-Z1 recreates music with exceptional presence and coherence.

Acoustic structure

With its coaxial layout and time alignment control, the SA-Z1 achieves both broad frequency response and accurate waveform at the same time.

Precise sound reproduction
'Tsuzumi' woofer layout for a deep acoustic field
I-ARRAY™ tweeters for wider frequency and off-axis response
Rigid body minimises vibration

The electronic circuitry and signal processing architecture in the SA-Z1 have been developed using the latest expertise from across Sony to reproduce High-Resolution Audio with ultimate fidelity.

Custom architecture on FPGA processor

Uncompromised music reproduction

Sony's engineers realised early-on that typical, off-the-shelf DSPs could never draw optimal performance from their unique D.A. Hybrid amplifier and coaxial speaker design. To overcome this, they built an original architecture on a FPGA (Field Programmable Gate Array) from scratch – the most advanced signal processing for the most advanced digital architecture.

L/R synchronisation

Left and right speakers in perfect harmony

The OFC cable that transmits the high-speed differential signal between speakers is engineered to suppress signal reflection and loss, and shut out interference. This ensures accurate time alignment between left and right speaker – crucial for reproducing spacious sound.

Convert any source to DSD

DSD Remastering Engine by FPGA

The DSD Remastering Engine lets you convert all PCM music sources into DSD 11.2MHz. The technology uses the FPGA to convert any signal into the DSD sound format.

Preserving the feeling

New DSEE HX™ analyses song type by AI

Audio upscaling is improved even further by our new DSEE HX™ processing which intelligently recognises instruments, voices and musical genres. By identifying these and the relative energy of the audio, it can accurately rebuild audio lost during digital compression, for a full fidelity experience, even with compressed formats.
