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!
