The last time I reviewed an Edifier product was many years
ago. It was a tiny little USB-powered computer speaker. My, things have come a
long way. The Edifier S3000 Pro speakers can certainly be used as computer
speakers. But they are powerful, versatile and impressive speakers which work
perfectly well as the main music speakers for a large room.
Edifier S3000 Pro Features
The first thing I noticed about these speakers is their weight. I like heavy speakers. It indicates solid construction. And that goes with reduced sound colouration and reduced distortion. The Edifier S3000 Pro speakers are heavy.
There are two of them in the Edifier S3000 Pro carton. They
are a stereo pair or, as Edifier calls them, 2.0. The left speaker weighs 10.35
kilograms. The right one weighs 10.45 kilograms. The extra weight for the right-hand
speaker is because it has a little more inside. I’d call them
large-bookshelf-sized. They are each around 360mm tall, 210mm wide and 300mm
Both speakers are powered. Both plug into power points. But
only the right one has inputs.
They connect together wirelessly using KleerNet wireless
technology. This is a system that apparently supports near-lossless audio at
16-bits and 44.1kHz sampling. The two speakers are factory pre-paired, but can
be re-paired should the connection somehow be lost.
The inputs are:
Bluetooth 5.0 with aptX HD support.
Stereo audio via RCA sockets.
Stereo audio via balanced XLR sockets.
Digital audio via optical input.
Digital audio via coaxial input.
USB Audio from a computer via USB Type-B
The Edifier S3000 Pro speakers come with a remote control, two power cables, optical and analogue cables, plus a USB cable for connecting to a computer.
The grilles are removable and are a little unusual, in that
they are quite see-through. They are secured by four pins around the
bass/midrange driver. Beneath the grille on the right-hand speaker is a small horizontal
display panel. This shows which input is currently selected.
Inside each of the Edifier S3000 Pro loudspeakers are two
drivers. The bass/midrange is a more-or-less conventional 165mm unit. But the
tweeter, well that’s different. Edifier variously describes it as a “planar
diaphragm tweeter” and a “planar ribbon tweeter”. Generally, “planar magnetic”
and “ribbon” tweeters are considered to be two different design techniques. Without
more information, it’s hard to say which these are.
But what they are not is the usual dynamic speakers with a 25mm or thereabouts dome. Both planar magnetic and ribbon use a lighter moving assembly to produce higher frequencies than dome tweeters. And they are generally rarer and more expensive. These ones have a phase plug or wave guide in front of them, which likely reduces the directivity inherent in flat panel transducers. And they seem to be mounted in a gentle horn, increasing their output efficiency.
The built-in amplifiers provide 120 watts to each
bass/midrange driver and 8 watts to each tweeter.
“What?” I hear some crying, “Only 8 watts for each
tweeter!?!” Don’t worry, that’s plenty. In the real world, as in the world of
music, sound intensity diminishes rapidly with frequency. The power proportions
are about right.
Edifier rates their frequency response at 38 to 20,000
I used my old smashed-up Google Pixel 2 phone to confirm
that the speakers really do support aptX HD for Bluetooth. The XLR inputs are
probably overkill for speakers at this level. Don’t get me wrong, the Edifier
S3000 Pro speakers are very good. But probably not quite good enough to be
paired with the kinds of source devices which have XLR outputs. I didn’t have
any appropriate equipment to hand with those outputs.
Normally when reviewing speakers, I put them on my secondary
stands. But these were a little too large, so I put them in on the stands
normally occupied by my $2,000+ passive loudspeakers.
In short, the Edifier S3000 Pro speakers are real high-fidelity
loudspeakers. They run quite loud enough to fill my 5 by 7 metre office with
Initially they seemed a touch bright. But around the back
are bass and treble level controls. I take it that they adjust the relative
balance of tweeter and bass/midrange. Backing off the treble control from 12
o’clock to around 10 o’clock tamed that and brought them into fine balance.
The sound produced, especially when they were turned up to a
good high level, was dynamic and lively, while retaining that balance. There
was excellent detail, with the tweeter delivering everything in the music. Again,
there was a touch too much emphasis of surface noise with LP playback, but the
tweak I mention fixed that.
I did have to be careful, though, switching between inputs.
The output from my phono pre-amplifier is pretty respectable by the standards
of such things, but it was still much lower than the Bluetooth or optical
inputs. A couple of times I switched over while the level was up high for the record
playing input, only to have one of the other inputs blast out some ten decibels
higher than was comfortable. Yet the speakers happily took it.
Plenty of bass
The bass performance of the Edifier S3000 Pro speakers was a surprise. A good surprise. Edifier puts the bottom limit at 38 hertz. I’d say it easily reached that and went beyond it. For example, on Janis Joplin’s excellent 1969 album, I Got Dem Ol’ Kozmic Blues Again Mama!, there’s some accidental bass in the track “Maybe”. This is mostly a mixture of 50 hertz and 27.6 hertz. Both frequencies were clearly being reproduced by these speakers.
That made for a good, solid bass grind from the Edifier
S3000 Pro speakers.
If there was a weakness, it would be in the imaging. There
was a good wide spread, but not quite the precision in the location of the
images, nor the sense of depth and height, that my regular speakers deliver. That
said, those speakers cost around twice as much. Nonetheless, I do wonder whether
things could be improved if there were an option to connect the speakers by
wire. The way they are, only the wireless connection is possible.
USB Audio Input
Naturally, I also played a fair bit of music through the Edifier S3000 Pro speakers using the USB connection. When you select the USB Type-B input, the speakers turn into a USB Audio device. If I understand the somewhat unclear instructions – and it seems to be the case – they conform to the USB Audio Class 2.0 standards. That means a driver is required for Windows 7, 8 or 8.1, or Windows 10 before the early 2017 “Creator’s Update”.
When I plugged it in into my Windows computer – with the
current version of Windows 10 – the speakers failed to appear in the list of
available devices. It seems that the USB circuitry isn’t powered up until you
switch to it as an input. When I did, it appeared in the Windows Speaker
dialog, with sampling rates of 44,100Hz, 48,000Hz, 96,000Hz and 192,000Hz and
resolutions of 16 and 24 bits on offer. Satisfied, and intrigued, I fired up
Foobar 2000, my preferred high-resolution audio player, set the output to the
WASAPI connection to the speakers and set some music playing. The music I chose
was 44.1kHz, 16 bits. It played perfectly.
The reason I was intrigued was that missing from the
reported list of supported sample rates were 88.2kHz and 176.4kHz. These are
both rarer high-resolution audio formats than the others, nonetheless some
music does come at those rates. I tried sending some 88.2kHz music to the
speakers and Foobar 2000 came back immediately and told me it was an invalid
format for the speakers. Oh well.
So, I sent the Edifier S3000 Pro speakers some 96kHz, 24-bit
music, a very common high resolution format. It played after a fashion, but
with a nasty, crunchy noise overlaying much of the music. I had the same result
with 192kHz, 24-bit music. So, I backed up to 16-bit, 48kHz material and the
result was … the same. Up to that point I’d been thinking that perhaps there
was some bandwidth problem, but everything can handle 16 bits and 48kHz.
Then I switched the output over from WASAPI to Direct Sound,
which is the standard Windows system for handling audio. And all those tracks
now worked fine.
Does it matter?
WASAPI vs Direct Sound
Computer audiophiles generally use WASAPI or ASIO for outputting music to external digital to analogue converters. WASAPI stands for Windows Audio Session API. It’s a standard part of Windows. ASIO stands for Audio Stream Input/Output and is a proprietary protocol developed many years ago by Steinberg to support its professional audio gear. Both of these allow software to communicate directly with audio hardware.
Windows Direct Sound is a little different, despite the name.
It manages all sounds. So, for example, if you’re listening to some music and the
computer makes a notification sound, DS will mix it in and you’ll hear it as
well. It will also convert all standard PCM formats to something that the audio
hardware will understand.
So it’s very useful. But because it does all that mixing
and, possibly, conversion, audiophiles tend not to trust it and prefer WASAPI.
I am somewhat surprised by the fact that WASAPI doesn’t work
properly with these speakers. I’ve reviewed many DACs and computer speakers ranging
in price from $99 to $9,000, and every single one of them has worked properly
It’s possible that the speakers do actually need a special driver to work properly with WASAPI. The manual is ambiguously written. It gives a couple of web addresses “for details”, one for XMOS (the USB hardware maker) and one for its own site. Both pages are dead. Exploring the sites further didn’t yield any results.
WASAPI Now Fixed
Well, if all else fails, you can always ask for help. I emailed Edifier tech support using the contact page and asked if there was a driver. The next day a response came back as follows:
And it worked! Two points, though. The first is, why isn’t the driver available on the page for these speakers?
Second, this driver doesn’t support either 88.2kHz or 176.4kHz sampled music files. However it does play the more common 48kHz, 96kHz and 192kHz files.
But that’s getting pretty nit-picky, given the price and other virtues of the Edifier S3000 Pro multimedia speakers.

And remember, you can turn them into network-capable speakers cheaply simply by adding a Chromecast Audio.
