M-Audio BX4 - An Upgrade For Your Sound!

Are you unhappy with the sound quality of your built-in computer speakers? Looking for a better listening experience for your favorite music, podcasts, live streams, computer games, video calls and conferences? The M-Audio BX4 studio monitors are the perfect choice! Compact, attractive and easy to set up, with the M-Audio BX4 desktop speakers you’ll hear your media better than ever!

Immersive Listening Experience

Immersive Listening Experience

Designed for live streaming, podcasting, gaming, watching movies or simply enjoying your favorite music, the M-Audio BX4 monitors deliver an impressive 120 watts of crystal-clear sound in an attractive, stylish design. The two-way design uses an MDF cabinet that prevents acoustic interference, paired with a bass-reflex port that provides smooth low-end and solid punch from the Kevlar low-frequency drivers.

The improved bass-reflex ports deliver especially deep frequencies, making games, films and songs a truly immersive experience. Add computer-optimized silk-dome tweeters for crystal-clear highs and precise stereo imaging — the BX4s provide brilliant sound quality for every multimedia application.

Optimal Connections

The rear panel features 6.3 mm, 3.5 mm and phono inputs, so these speakers are compatible with almost anything. There’s also a 3.5 mm AUX input and a front headphone jack for tablets, computers or phones.

Customizable Sound

The BX4s offer a fully adjustable listening experience. Use the High-EQ and Low-EQ controls to tailor the perfect sound for your environment. The speaker-position switch lets you choose which speaker is left or right — especially handy for left-handed users who prefer the front-panel volume control on their left side.

MPC Rhythms Included

MPC Rhythms is an industry-standard recording software. This great audio and MIDI recording package is invaluable for musicians, podcasters, live streamers or singer-songwriters who want to develop, record and share their ideas with the world.

MPC Rhythms includes 3 virtual instruments — TubeSynth, Electric and Basslin — plus 80 FX plugins such as AIR Channel Strip and Half Time, and access to 2 GB of factory content with the additional F9 instrument library. With this amazing software recording bundle you can turn ideas from imagination into reality.

Absorber Plates

The Pronomic ISO stand absorber plates are ideal for placing under studio and near-field monitors. The foam reduces disruptive resonances and unwanted vibrations, improving your speakers’ acoustic performance. Not only does reduced mechanical vibration transmission improve the sound, the two-component design also helps optimize playback. This construction lets you position studio monitors at five different tilt angles to perfectly align them with your listening position.

Your Perfect Sound For Music Production, Live-Streaming & Podcasting!

Great monitors, very satisfied

As a beginner in music production in my home studio with Cubase 13 and software and hardware from Native Instruments, I was on the lookout for inexpensive studio monitors, as my old ones were completely garbage and were screaming. I found what I was looking for at Kirstein and was able to buy some pretty decent monitors on my dwindling budget. I have to say.....I am pleasantly surprised at what these small monitors can do. There will certainly be considerable differences in other price categories, but better, wider, bigger, etc., is always possible and, in my opinion, not necessary for the time being. For my battered ears, these monitors are a real treat and worth every penny. I find them to be very clear, with a good surround sound and well-balanced highs and lows, although I don't have the trained hearing of a professional in a recording studio. But I think you can work very well with these monitors and they will give you pleasure for a long time. In terms of value, they seem to be quite stable and solidly built and I think the price-performance ratio is very reasonable. Of course, I don't have any real objective opinions to compare them with. The connection was uncomplicated and the foam pads of the same color are very nice, as they absorb vibrations wonderfully.
I was also particularly pleased with the speed and friendliness of Kirstein's customer service. There was nothing to complain about, the order was processed promptly and the packaging was also good. So my conclusion: If you are looking for inexpensive yet good studio monitors for games, music production in the home studio or simply for listening to music and don't have such a large budget, these monitors are a really good choice. For me, a clear recommendation to buy and definitely not money badly spent. I am therefore happy to give them a full 5 stars.
Double whammy

Have been looking for speakers for my USB audio interface and then had the question whether Mackie, Presonus or M-Audio. In the end it was the M-Audio speakers because of the slightly larger (4.5 inch) bass speakers. It's also nice that you can make a sound adjustment on the back to adapt the speakers to the acoustics of the home studio. The switch that adjusts whether the active speaker is on the left or right is also a nice gimmick, of course you could also achieve this simply by swapping the connection cables. It's also nice that the important controls, headphone jack and aux input are on the front of the main box, which saves plugging around on the back panel.

The absorber plates I had to shorten the length a bit, because the shelf on which the boxes are only has a depth of 26 cm. Carpet knife and cut, fits. The boxes are stable on the absorber plates and can also be tilted a little forward when they are mounted higher than the ears of the user.P

Now to the sound. It was loud at first, even though I had just set the volume control to "9 o'clock". But ok, at the audio interface the output was fully turned up and at the DAW too. So first of all the levels on the audio interface back and the whole leveled at room volume, knowing that there is still a lot of room for improvement.

The sound is fantastic, no comparison to the small "roar cubes" that previously stood on the desk. The music playback is a pleasure, the sound comes across clearly without distortions or resonances. Perfect sound quality for a small budget.
