Samsung has announced its new portable Bluetooth speaker, Sound Tower MX-ST45B. For now, it is only available in Brazil, but it might hit other markets later this year.

The South Korean tech giant showcased most of its 2023 lineup at Mobile World Congress 2023. According to the latest press release, there is more to it. Samsung has announced its new Sound Tower MX-ST45B portable Bluetooth speaker launched in Brazil. The company mentioned that Brazil has differentials that make the equipment perfect for any occasion, including outdoors.

After revealing its 2023 lineup at Mobile World Congress, Samsung launched its latest bluetooth speaker in Brazil.

"Samsung is already known for offering equipment that elevates the sound experience in different contexts, such as Soundbars, perfect to be used in conjunction with Smart TVs for unparalleled immersion. With the new Sound Tower MX-ST45B, the proposal is to offer a practical, easy-to-use, portable product that turns any meeting into a real party thanks to its sound power, long-lasting battery, and LED lights that liven up the environment", says Julia Prozzi, manager of audio products at Samsung Brazil.

It is the first addition to the company's 2023 audio lineup, and it also came with a launch promotion. If you buy the new speaker between March 1 and March 15, you will be granted a Spotify gift with a six-month premium subscription.

12-hour battery life, IPX5, and more

Samsung Sound Tower MX-ST45B has a triangular shape measuring 281.0 x 562.0 x 256.0mm in dimension and weighing eight kilograms (around 17.6 pounds). The company tests revealed that the new speaker includes quite an impressive battery that lasts up to 12 hours. It comes with an IPX5 water resistance rating, which means it is durable against accidental spills and rain. It supports TVs and up to two smartphones simultaneously, thanks to Bluetooth connectivity. "For those who are in the habit of connecting another audio device via USB, the Sound Tower has such an input. Finally, the DJ Effect gives a special touch to each hit, as it allows different effects and configurations for each musical style using the Sound Tower app, exclusive to Samsung," says the company.


After revealing its 2023 lineup at Mobile World Congress, Samsung launched its latest bluetooth speaker in Brazil.

The tech giant's new speaker can deliver up to 160W RMS when plugged into an energy source. If you are willing to use it on battery, it falls to half and offers 80W RMS. It also has a multi-connection feature that allows you to connect it with up to 10 Samsung speakers. All devices sync up and let you have a "very loud" party. The embedded LEDs have an equalizer-like feeling as they match the tempo of whatever music you are listening to. Its design, battery life, and general specs fit both inside and outside use.

Price and availability

Currently, it is only available in Brazil. The Samsung Sound Tower MX-ST45B is priced at R$2,999, which makes around R$579. It will eventually reach other markets worldwide, but Samsung hasn't specified a date yet.

    Thanks for this, Martin, I will give it a try. I have been attempting to edit vids with Machete Lite sans success;the online instructions give a sort of overview and a description of the “buttons” but no real step-by-step; or maybe I am just too dumb.

      It works really nicely. YouTube on the other hand added borders again, haha, that felt kinda strange.

      yeah this didnt work at all, and your instructions are a bit off, the options/ menus GUI is not exactly like you describe

  3. *!:DECCAS:!* said on October 19, 2012 at 3:37 am

    I followed the instructions, but when i save it still has borders. I crop it, the black goes green, i click ok, i click close then save. I can’t preview it in avidemux as it just crashes. what am i doing wrong? (Windows 7)

    I followed all instructions, I can’t play the video in preview, when it saves, it’s only audio. Using Windows 7, please help…

    Waste of time. Like everyone else I get what I started with but unplayable.

    Video Crop and other settings are in:
    (above) Video > Filters…
    Then on main screen (The video will show normal, then saved, the filters will be applied)
    –Video Output:
    Mpeg4 AVC(x264)
    –Audio Output
    –Output Format
    MP4 Muxer
    >>>>>>>>NOTE: dont use copy on video/audio output because the filters don’t apply

    This worked perfectly (ubuntu 12.10). Thanks, I’d been pulling my hair out trying to get iMovie on a Mac to do this without destroying the video quality.

  9. Swaffles said on December 3, 2012 at 4:09 pm

    Thank you so much for the tutorial! It worked perfectly except that it altered the colors of my .avi file. It changed everyone’s skin color to blue and I think the tones have flattened? Is there a way to fix that?

    Many years later this came in handy at the perfect time. Thank you for posting this.

    I did exactly as you stated. I brought in an AVI file, tried every video output (1 at a time) , did a crop, saved the file. Every output had no video codec.

    1. Martin Brinkmann said on March 13, 2016 at 4:34 pm

      What do you mean by that? That you cannot play the video?

  12. Irene said on February 15, 2017 at 4:45 pm

    I imported a video and cropped the screen in filters to suit my needs. When I save the file it only saves 7 min 10 seconds. My video is 30 min long and My A and B points are the beginning and the end of the file. Any idea?

    1. Martin Brinkmann said on February 15, 2017 at 4:51 pm

      What do the A and B values read on the main screen?

      1. Irene said on February 15, 2017 at 5:15 pm

        I closed everything and opened it again and now it saves the whole video.

        Thanks for the quick reply anyway :)
