I bought them as low-budget monitor speakers when I started doing computer music.
To this day I use them connected to a Presonus AudioBox 44 VSL soundcard.
I still use them for computer music with Nuendo.
It's true that these speakers have lots of lows, but fortunately there are two knobs at the rear that allow you to adjust the low and high frequencies The ON/OFF switch is also practical.
It's obvious that these speakers don't have the precision of professional speakers, but if you listen to them regularly, you can easily make good use of them, always taking care to listen to your mixes on other media (headphones, speakers), so you can find the right balance between the different sound reproduction tools.
When I read that some people say the sound isn't good, I can't believe it. I think the bad sound they get is due to their soundcard or bad settings of the latter. Personally, I never crank them beyond halfway and I never have distortion.
The dynamic response is good.
I've been using these monitors for 6 years.
I've had the opportunity to listen to other monitors in a studio, but they are out of my reach. At home, I use the Behringer MS 40 as main monitors, but to check my mixes I also use a couple of Hi-Fi Tensaï speakers connected to my '80s JVC amp a pair of Beyerdynamic DTX 910 headphones, plus a pair of AKG cans whose model I can't recall. I also use my Phonic P620 to listen at loud volumes.
From my point of view, this product is a great value for money and it features intelligent connecting possibilities, frequency controls and an ON/OFF switch on the front panel, as well as an LED indicating the power status.
You need some time to get used to them and not let yourself be mistaken by their major defect, which is to highlight the low end.
I wouldn't hesitate to buy them again.
I must point out that I'm not a pro of computer music, it's only a hobby for me.
The Behringer MS 40 monitors are very inexpensive and have a great frequency range with a flat response. I used these for over a year and had some isolation pads under them on my workstation. I had these facing inward at ear level to give me the best possible mixing experience. The difference between these monitors and most others is that it gives you options on it to plug in your MP3 player or keyboard right into it without having to go through an interface to hear the sound. This comes in handy if you want to use your monitors just to listen to music through or take them with you for your keyboard but it is a feature that I did not use too much so it did not matter to me either way.
The sound was pretty good, the response was pretty flat and you can turn these all the way up and not have to worry about losing any sound quality. Because these are so cheap it is great to have a pair of them so that you can use them for multiple purposes down the road if you need to.
There are 20 watt amps built into each monitor but that is not enough power to really get a huge sound. But for the price that these cost you can not expect a much better sound. My favorite feature of these speakers is that there are treble and bass knobs on them so that you can adjust them accordingly. These feature is really only good for when you are listening to music through your mp3 player or using them with your keyboard. Because when using them for mixing you never really want to mess with the bass and treble because that can affect your mix terribly on the high and low end. You will love this monitors because they have multiple purposes but if you are looking for a big sound then these might not be the best option for you.
I bought these speakers for lack of space. I have used them to mix (DJ), as well as to do computer music and some other multimedia uses on a PC.
The audio reproduction is good if you use them as multimedia speakers. They are limited if used as studio monitors. The sound quality is not great, the lows distort pretty fast and the highs are not very present. The controls allow you to improve things.
Expensive for multimedia speakers, but not so for studio monitors. Might be okay for small and not-too-demanding budgets. Personally, I like them as multimedia speakers but not for music, to tell you the truth.
I'm very disappointed with these monitors, too. I like the brand, but this is an abuse, the sound is unadjustable. As others have described, the highs are fine, that's true, but the mids are absent and the lows muddled. Indeed, they lack lows, but if you increase them, the sound turns unpleasant and eat up the mids. So the only way to get a decent sound is to decrease the lows and add a subwoofer to the system. Fortunately there are controls for the lows and the highs. Although I would even increase the highs further if I could. Resell them? I use them to watch TV, the sound is all right for that even if less precise, they are pretty powerful for their size and the connections provide lots of possibilities. Or to transform them into a Hi-Fi system, connect an MP3 or CD player, or any other player you use to listen to music. But they should be forbidden for mixing.
