Punching well above its price point....WOW!!
DjChrisW 25.01.2022
Firstly thanks to the people at Thomann for a first class customer experience, having no issues having my purchases shipped to the UK.

Now onto the speakers!! I'll just dive straight into the sound quality (that what we really want to know!).
I can only compare these speakers with what i was using for mobile djing. A set of Yamaha DXR15 (if you know these are well regarded in the dj world) .
Clarity is up there with them. My opinion is there's a little too much treble than im use to , but a quick dial back on the dsp eq by -2 fixes that for my taste.
There's also a good amount of bass for a 12" more than what i was expecting, nice a punchy. Very impressed!

Yes they get disco loud with no distortion, clipping or sound degrading.

I will say that i was a bit hesitant buying a cheaper brand at this price point, and not being able to listen to it before purchasing.
I went with the many other reviews saying the same thing.
I couldn't be more pleased with these speakers

Bottom line
For the price of these speakers they are punching well above there price point!!

Pair it with a Pyrit 212a and well....... What a system!!


Very good budget speaker.
Whistleblower 05.03.2021
I bought this speaker for many different applications (live music with mostly acoustic bands, background music but also for a little DJing...mostly it's with about 40ppl. but sometimes it's also about 80-110ppl.)
But I'm a student, and that's what my budget was like - small.
Because of the price and because I had already listened to the 15" version, which impressed me, I decided to buy two of them.
While ordering the speaker, I was not really convinced about quality and so on...but when the speakers arrived, all those sorrows were washed away.
While testing them for the first time (hi, mid, bass all equally on 0) I noticed that they have relatively noise ground sound...but when you put music on, you won't notice ;).
The sound is just amazing; fresh highs, good mids and a fantastic bass. If you ask me, this speaker is definitely comparable to some 15" ones.

Unfortunately one of them had an issue with the stand-by mode. But after sending it to Thomann, everything was nice (so thank you, Thomann team:) )

Long story short, I'm very impressed and I recommend this to everyone who is looking for very good speaker for a very good price. Because you can easily put this speaker in any situation, and the speaker will fill your expectations.

EDIT: After a couple years of use, they still play fantastically. Since the one retour, I never had any problems encounter with them at all. They proved that they are here to stay. Especially the built-in DSP is something that I learnt to appreciate - I didn't know it from my 'old' speakers and had to get used to it. They worked perfect in any kind of venue (even churches. I can only recall three times when I added a subwoofer and I only did that when playing music outdoors. So still a 100% YES!


Great for the money!

Bought this. Intended use: a live event (a small gig in a small pub and as monitor for another bigger gig). This speaker held itself really well on stage, along with a bigger PA system I had from before (2 215 fullrange passive speakers).
The clarity is good, up to big volumes. Even when the input signal is clipping, the speaker knows what to do and handles the job well. At higher volumes I have noticed increased treble, which is a bit annoying to the ear, but with a slight EQ adjustment from the mixer or the DSP on the back of the speaker, all goes well.
I totally recommend this if you don't have a ton of money to throw at a PA system, but not only if you're on a budget. This is a great speaker for any budget.

Later edit:
Also, if you don't buy a B-Stock, don't forget to leave the speaker with music for a while to break it in - I seem to have forgotten this small detail, that's why I've been hearing that harsh treble back then, but now after breaking the cone in and having it play music for a while, everything sounds fine and in place!

Later edit:
After a couple of days of using it at home to play backing tracks while recording, I found out that the integrated DSP has some weird computing, because sometimes the sound fluctuates in volume and frequencies - for example it might cut bass once in a while. This happens after two hours of this speaker being on, so it must be something related to the heat, maybe?


Price equal to quality
Arturelis 12.04.2018
I've bought two of these. Compared them with EV ZLX 15P and EV's sounds much better and even has more power, though in specification DSP112 says otherwise. I've read someone's review, taht DSP 112 are equal to EV ZLX 12p - this is not true. I would say so - if you need something cheap for medium quality sound - then OK, otherwise it's not worth even that sum. Clarity of sound is very bad, not so powerfull as says in specification. Other features are OK.
