Finally a speaker that doesn't disappoint with its performance. Crisp and airy highs that don't pierce your eardrums and don't tire you out after 10 minutes of listening. Warm and revealing mids and true, heavy/deep bass that outperforms many speakers twice its price (that claim to have bass). In the sea of bright sounding speakers, this speaker stands out for its neutral and warm sound, large bodies, volume, control, soundstage, without being overly forward (in your face sound). In walnut color, it is beautiful! In movies, it has such deep lows that you don't need a subwoofer. It pairs well with the Yamaha a-s 501, which has the necessary power to drive them since they are at 6 Ohms. Bravo to Q Acoustics.

Really good indeed, it depends on personal taste...
This bookshelf series is good, although for me the existence of 3 similar models (specifically, the 3010i, 3020i, 3030i) might be a bit excessive. For the enthusiasts, there is also the "Concept" series, with the concept 20, which has been around for a few years, concept 30 (recently released), and Concept 40 (floorstanding), with a slightly higher cost. They have a greatly reinforced cabinet, even better construction (compared to the already very good one), and truly differentiate the final sound result (even if they use the same drivers in some cases)!
Worth it.
*To the company, since I see you like the sound signature of Dali, why not try their larger series (Oberon, P, X, and Opticon), it's worth it.. :)

The speakers are truly exceptional. Clear sound, ideal bass.
From an aesthetic point of view, perhaps one of the most beautiful speakers at this price.

If you combine them with the Q-Acoustics stands, they provide a very nice acoustic result

At 339 euros now is a first-class opportunity.

Once again... "what a beautiful speaker this is !!!".
What a beautiful, full sound with volume!
Its price now at 369 euros seems good (since the price in England, according to English Hi Fi magazines (a few months ago), is 329 pounds, although I see it quite more expensive on various sites, but at richersounds 269 pounds, which means it may now be offered at lower prices), so do not think too much about it, unless you want to wait to see if its price drops - anyway, put it on your list from the beginning (it is also beautifully in walnut).
OF COURSE YOU WILL LISTEN TO THEM WITHOUT THE FRONT COVERS.

With this speaker I agreed with a Hi Fi Choice (because for the mission qx2 I did not have the same opinion at all) that I recently got, which even advances it more than I do, concluding its review with the phrase "even at twice the price, it would still be a no-brainer" and in the summary OUR VERDICT with the phrase "a stone-cold bargain" - maybe a bit of an exaggeration for me, as far as the point with twice the price, but certainly not far from reality because the speaker is indeed amazing (even if I am still stuck with the Dali Spektor 2).

The first thing that comes to mind when you hear this speaker is how wonderful it is.
If you do not have any particular tastes in how you want the sound to be, to strictly adhere to them without any compromise, e.g. to be up front or to be very lively and bright or to have very strong treble or to have a lot of nerve and aggression, things that you will not find in this speaker then you have no reason not to buy it, but even in the case that you have some such specifications, you can only bow to the sound of the 3030i.
Control, information, maturity, warm and full sound, emotion, volume (big sound), bodies, soundstage, bass, balance, culture and politeness in the right dose (sound that does not tire you) so that it respects your ear (and helps mediocre machines or recordings sound good) but it also has charm and never makes the music sound uninteresting... what else to write. More old school sound (in a good way) and huge, better prepare for it, because many modern speakers in order to give a provocative analysis and clarity do not give so much importance to the scale resulting in the sound being a bit small.
Here is a case where I will not elaborate on a speaker.
The calm power, almost absolute choice at 369 euros.
You do not need to wait to settle to understand what you are dealing with. It convinces you straight away with the first listen.
Now I have both sides of the exceptional to choose from each time how I will listen.
I.e. dali spektor 2 for color, liveliness, brightness, emotion, enthusiasm and passion and q 3030i for maturity, full but also warm and informative sound and clearly with emotion.
End of hi-fi observations and descriptions and time for music.
I think it is obvious how warmly I recommend it (and I am also curious about how the smaller 3020i will sound where the bass is less (so they will fit better in small listening rooms) and the midrange will be more pronounced).

Quality appearance and construction.
Warm sound with strong bass.
An all-around speaker that covers all levels (at least in the usage I do, mainly music and movies)
I think it's a very good purchase for 400€.

After extensive research, I ended up with these. I wanted them exclusively for listening to music from vinyl and CDs. Small size with big and high-quality sound was the goal, and these are exactly that. I have changed several speakers in my life and have listened to even more, resulting in having some opinion. Their sound presence is comparable (maybe even better) than many speakers, even those in a higher price range. I suggest not buying speakers of this category, regardless of price, if you don't first listen to these. You won't regret it...

P.S. Because I searched a lot and to facilitate others in their research, as there is no perfect speaker for everyone, the most notable competitors are, in order of price, the Elac Debut B6.2, the Triangle Borea B03, and the Klipsch RP-600M. See and listen to all of them if you can, sound is something particularly subjective and maybe one of them suits you better.

I hope I helped!
