Have taken delivery of a pair of QSBs..... and before I say anything else ... WOWOWOWOWOW!!
They come in a clear, plastic, box-like outer package with a sort of riveted edge which contains the speakers in their carry case and a fairly low-key cardboard descriptive label which lists the following:
2 x 15W phenomenal 30W equivalent peak power output
Sub-compact completely portable
Powered solely by USB port of host device
Redefines USB audio - full range of linear, high-power, low distortion audio
Greener, lower power consumption, cooler sudio
Extremely wide listening angle, up to 180 degrees
Detachable audiophile grade speaker cable with RCA connectors
Direct digital audio output from computer
Bass Boost for even deeper richer bass
Designer carry case (9 x 20 x 10 cm)
Closed-box design, Mechanical dimension 85mm x 85mm x 85mm
Patented NXT Flat-Drive Technology (BMR - Balanced Mode Radiator)
High Performance 8 Ohm 40mm Flat Drive BMR Driver
Patented Ultra efficient low power consumption amplifier
Bass enhancement filter
1 x mini USB port
The carry case itself is black with a red stripe running around the middle length-wise and has a sort of tyre-type finish to the top surface. A nice quality feeling case that will probably last well.
Opening this reveals the two jewel-like piano black gloss finish speakers with silvered edges. These too feel a nice weight and good quality. In between them the two cables, one RCA connector cable (about 1 metre) to link the speakers together and the USB cable (about the same length) to connect to the PC. A very simple quick start guide directs you to connect everything up correctly but frankly you would have to be pretty dim to not be able to see immediately what to do....
The PC running XP immediately recognised a new device and shortly displayed a new QSB HID (human interface device) had been made ready. Click on a track and immediately music bursts forth without any need to configure the PC to use these speakers in preference to the default device.
And? Well I have to say I am flabbergasted that a purely USB driven speaker system can produce (a) the loudness that the QSBs do but also (b) the precision and hi-fi quality of the sound; simply extraordinary. They sound brilliant and to make sure it is clear no batteries are needed nor are any built in as some people seem to think, they are powered directly from the USB port.
Playing various different styles of music reveals quite a lot or at least confirms exactly what one would expect of the performance based upon the technology behind them. I have a large 28 x 20 x 15ft high sitting room; the sound from these speakers easily fills that room and standing at the far end of it with the laptop at the other end the sound is brilliant and expansive and pretty much omni-directional. Certainly the claim of a 180 degree sound stage is justified.
With the speakers positioned about 6 feet away and at full volume they are uncomfortable for me to listen to. Of course everyone's tolerance varies and I am sure many people will be happy to play them at full blast most of the time. For me that isn't necessary and I hope gives a fair indiciation of the loudness available. Is it equivalent to 30W at peak? I wouldn't be able to tell you, I am not that much of an audiophile to be able to judge. Are they loud? yes Do they fill a large room with sound? Yes. Is that sound great quality? Yes, brilliant. Bass? Really good.
As an update, having taken them into the office that is approx. 45ft by 20 ft wide with a very high 20ft ceiling with the QSBs plugged into a MAC, at full volume it is necessary to shout over the music to be heard and it fills this room with ease. Everyone there was amazed and impressed by both the volume and quality of the sound they make and the quality of the units themselves. SoundScience you have a winner I believe.
