Okay, I will start by saying that I thought I had at least bass with my old Logitech 5.1, because of the subwoofer... I was wrong... I just had loud noise. Now I have bass!!! Clear, powerful bass!
I have had these speakers for one day.
As for the construction, initially, they are heavy (HEAVY!!!) and sturdy! They don't move from the desk even when I want to move them a little, they don't creak and they don't seem like they will ever start creaking! Excellent construction.
The remote control is also heavy (compared to others), sturdy and beautiful.
The packaging is very well done, the speakers with protective cloth, hard plastic on top and inside a bag. The cable that connects the two speakers is quite long and reinforced, not fake. Inside the box, it had all the cables you need, 3.5" jack to 2 RCA, RCA to RCA, USB A to B, and Optical! In general, all cables are long. Personally, I connected it to the PC with USB after downloading and installing the relevant drivers from the Edifier website.
In terms of sound, excellent, I set the sample rate from Windows to 192 Khz at 24 bit.
I have played classical (mainly piano), metal, rock, electronic, and they all sound great (mp3, flac, youtube).
The highs are nice and quite a few without whistling in your ear, the mids are full, and with the bass I lost my mind, I watched the speakers vibrate in the beat, and I smiled foolishly with my mouth open!
Anyone who is afraid they don't have enough bass, they do! And strong and clear!
I haven't played a game or movie yet, but I guess the sound will be equally impressive!
Behind the active speaker, there are knobs for treble, bass, and volume. The volume knob is also a button that turns off the speakers. The speakers also turn off from the remote control.
I also played music from my phone with Bluetooth, easy connection, the remote control has play/pause, previous and next, to handle the music without opening the phone.
The remote control has 4 modes, Monitor, Dynamic, Vocal, and Classic. These modes are nice, the Classic one I used with piano sounded sweeter, with dynamic I used other music, the sound was full, and the monitor is a nice addition if you connect them to a midi/audio interface!
One drawback, the remote control has to "look at" the active speaker to catch it. If it looks at the ceiling as you hold it, it doesn't catch. Personally, I don't care so much.
In addition to the above, the positives for me are their small size, not too big to be next to the PC monitor.
Overall, I am very satisfied with this purchase. They seem like they will stay in my office for many years without aging...
EDIT: 6 years later, the speakers have proven to be worthy of my expectations! They work like the first day, perfectly, without any glitches with their electronics, without any creaking from the years they have been playing! The only negative, which is logical, because I have them constantly in USB mode, the USB light (which has been continuously on for 6 years now) has become slightly dimmer than the other lights, something I only see if I happen to change Mode by mistake, but this happens with all LEDs without exception.
If for some reason they break, I will buy the same ones again!
