Wireless speaker is getting more and more popular in home audio, however, wireless speaker can’t reach high end audio standard, until now. Peoples always have a thought that wireless speaker can’t retain original sound. Popular wireless speakers, Bluetooth and WiFi speaker, have timing problem.
Now, we use DECT technology to break wireless speaker technical limitation: allowing perfect channel synchronization, avoid any data sharing and using the most natural codec.
We redefine wireless speaker standard : wireless speaker can perform better than wired speaker.
High Fidelity (HiFi) sound is the natural sound, sound with musicality
Ultimate sound is musicality. Musicality is true music as if you are in a live concert. Sound should be pure and clean, no deletion and no addition. An accurate 3D sound stage should give you the correct width neither wide nor narrow), correct height, correct depth of the sound. Live sound should be airy.
ONEclassic not only looks good, but also sounds great, too. By removing the timing error existed in most audio systems and our unique speaker design, ONEclassic delivers an unbeatable sound stage, excellent imaging and well-balanced sound. It truly connects you to the music performers and shares the emotions of them.
Wireless, no cable distortion
Cable distortion is a long term problem in high end audio system. A good speaker cable usually costs thousands of US dollars. In principle, cable has many kinds of distortion : copper resistance, contact resistance, phase distortion, non-linear group delay and noise pick up. The longer of the cable, the more serious the distortion.
By removing the speaker cable, there is no cable distortion in our High Fidelity speakers.
DSP crossover filter, no phase error
Conventional wired speaker use a passive crossover filter to extract low frequency deliver to woofer and high frequency deliver to tweeter. Passive crossover filter is made of inductor and capacitor filter network which induce phase shift : high pass filter (used in tweeter) is phase leading, low pass filter (used in woofer) is phase lagging. At crossover point, woofer and tweeter sound are not in-phase, sound image is lost.
We use DSP to run two high precision FIR filter, which guarantee woofer and tweeter sound are in-phase. You can hear a clear sound image.
Bi-amplifiers direct drive, no coupling loss higher damping control
Passive crossover filter also has energy loss problem. Even a powerful amplifier with super damping factor, passive component will highly degrade damping control, resulting in woofer and tweeter can’t play accurate sound.
ONEclassic speaker consists of two amplifiers, one for woofer and one for tweeter. This gives direct control to speaker drivers, woofer sound is rich and punching, tweeter sound is crisp and airy.
DECT protocol, perfect channel synchronization
Sound stage is the perception from our listening. An accurate sound stage gives you a sense of space and dimension of every element. Essence of sound stage reproduction is each speaker playing with no timing error. The sound going to left and right ears should be absolutely the same as if we are listening to live performance.
DECT protocol has channel synchronization process 100 times every second. Time error between left and right speaker is less than half micro-second, which is 50 times better than WiFi speakers.
Ultra low clock jittering, pure and warm sound
Accurate timing characteristic in DECT protocol can help to implement a short control loop for speaker clock locking. We use low Q-factor control parameters, speaker can lock to transmitter without having forward and backward error correction. Speaker master clock is stable, clock jitter can keep less than 0.5ppm. Low clock jitter can give pure and warm sound.
Asynchronization mode, isolated signal source clock jittering
Even speaker itself has low clock jittering, signal source (Smartphone, computer or CD player) with inject their clock jitter error to the speaker and destroy sound purity.
ONEaudio use asynchronization interface with signal source, speaker audio master clock is self-run, completely isolated from signal source audio clock.
Full digital design, eliminate the killer of active speaker: microphonic
ONEaudio speakers are fully digital processing, no need of analogy component to enhance sound character. Microphonic phenomenon is mechanical vibration on analogy component transform to electrical noise pick up, that is killer of most active speaker because their analogy circuitry is inside speaker enclosure with heavy sound vibration.
Without analogy component in ONEaudio speaker, of course, no microphonic distortion is induced.
All-in-one firmware, shortest signal path most clean and pure sound
We have spent 5 years to develop an all-in-one firmware loaded on high integration single chip. The multi-processors single chip includes high speed processor, dual powerful DSP, dedicated protocol processor and DECT radio transceiver.
We believe simple is the best. We narrow down signal flow and make it short. Sound is clean and clear.
Build your own sound, sound profiles and tone balance
4 user sound profiles and 7 steps tone balance are available to suit your mood and preference by simply pressing a key on the speaker. No need to change or adjust any accessories. Combining 2 setting, you can build your own sound.
It is handmade version built by see-through acrylic. Not only features the stylish outlook, but also its ability to produce extraordinary sound stage that other wireless speaker cannot. Bi-amplifier direct drive to speaker driver results in pure sound and better imaging.
