Are floorstanding speakers or bookshelf speakers with a subwoofer suitable for a 14 m² room for the Wiim Amp Ultra?

First, I'm very grateful for your recommendations.

Since many speakers have already been tested with the Wiim Amp Ultra from md-sound.de, I am convinced that my new Wiim Amp Ultra can produce excellent sound in my 15 m² room using only bookshelf speakers + active subwoofer.
), I'm considering choosing one from these candidates.

Dali Kupid – Ideal für kleine Räume (8–18 m²), wandnah aufstellbar, viele verrückte Farben https://www.whathifi.com/speakers/hi-fi-speakers/dali-kupid
Elac Debut B6.3 – Zum laut Hören, tonal ausgewogen, 14–24 m² https://www.whathifi.../elac-debut-3-0-db53
Q Acoustics 5020 – Extrem ausgewogen, schönes Design, 8–24 m² https://www.ecoustics.com/reviews/q-acoustics-5020



Very interesting, but these boxes were not recommended. , !!!

Wahfedale Evo 5.1
Canton GLE 30
Focal Aria Evo X N1

This means I have to choose between three bookshelf speakers: Dali Kupid, Elac Debut B6.3, and Q Acoustics 5020! Which one would you recommend for me?

And another important question: what size subwoofer would be suitable for these speakers?(15m2) Which one would be a perfect match? I definitely need your recommendations here too!
The only speaker on your list I have ever listened to was the Kupid. For the price I found it sensational good! (Wrong colors to make it a gift for a niece but that has nothing to do with sound.)

If these are the only 3 models you're willing to consider it is difficult to give a recommendation based on anything objective.

There seem to be no detailed measurements available for the Dali Kupid, so it is a bit of an unknown.
Elac Debut B6.3 might be promising because the larger speaker in the series (DF63) performs really well (link to review).
The only one of these which was measured in detail by a reliable third party is the Q Acoustics 5020 (link to review), and it is not a neutral speaker at all.

And another important question: what size subwoofer would be suitable for these speakers?(15m2) Which one would be a perfect match? I definitely need your recommendations here too!
I'll reiterate my recommendation for the SVS SB-1000 Classic (link) - it is not too expensive, it is reasonably sized, and performs very good if you don't need very high playback levels.

By the way, I look at it for a few weeks and I am really impressed by your knowledge and the way you share it here!!
Thanks, that is really kind of you to say!
 
What do you think of the Klipsch RP-600M II?
It is quite OK, especially for the price: see this link.

This one is a little bright out of the box, but takes EQ really well (due to nicely controlled directivity) so this brightness would be easy to fix with some EQ.

Directivity is on the narrow side so I'd expect soundstage would be slightly narrow as well, but with nicely focused phantom images.

On the other hand, Wharfedale Linton Heritage is an example of a neutral wide-directivity speaker. That kind of speaker gives a wider soundstage, but with more diffuse phantom images. I'd say such speakers give a bit more enveloping sound.

Directivity is a matter of personal preference - some people prefer tightly focused imaging (narrower directivity), and some prefer wide soundstage and more envelopment (wider directivity or even omnidirectional speakers).
 
I have a similar sized room and am using a pair of Q acoustics 3030i speakers and a sub but my amps are different
I have a WiiM ultra connected to a Fosi zp3 preamp which has 2x Za3 power amps it works well using the hpf on the preamp set to 80hz
Got the speakers for £205 a very good deal
 
I think it's the same for most people. This is why I usually recommend close-to-wall placement. It is the second-best option, albeit a compromise.


There are some on-wall speakers that come close, then you have in-wall/soffit mounted speakers, and cardioud-bass speakers.
But it is not realistic for most standard box speakers, indeed.

However, from the same table you can see that up to about 0.6m from the wall is still acceptable - this fits most typical loudspeakers.
I've got mine down to 25cm now. I'll see how that goes 🙂
 
I'm currently torn between these two options (maybe this is my final decision?). Perhaps the perfect compromise? If I go for a floorstanding speaker, the Dali Oberon 5 Dali Oberon 5, or a bookshelf speaker, the Elac Deput 3.0 DB 63 Elac Deput 3.0 DB 63? Would it fit in my 15 m² room along with the Wii Amp Ultra?

I'd very strongly suggest trying to listen to any speakers in a store before buying.
Having done that myself, I know that some speakers simply aren't for me regardless of the praise they get in reviews or from owners.
 
I won't be allowed to put my speakers 1.2m from the back wall. How many speakers can be placed 0.2m from the back wall? That would be a very low cabinet depth even without cabling.
I solved this problem myself by getting longer speaker cables and setting two positions in roomfit. The first is my "casual listening/movies" setting (aka "max WAF setting") with speakers (QA 3030i on stands) positioned next to tv and close to the wall, with seated position on the couch. The second is my "home alone/critical listening" setting with speakers pulled out about 1.5m into the room and with my listening chair placed in front of the lounge. Both settings sounding pretty great.
 
I also wanted something new, otherwise Teufel isn't as good quality as Elac.Larger speakers require significantly more space; if they are placed too close to the wall, the bass will sound boomy. You can read more about it here.Audio Physic

Roomfit takes care of the boominess. Even bookshelf speakers will sound boomy close to a wall. If you just want new speakers then that's also fine 🙂
 
I tested both speakers in a different room, not just a 14 m² room, but a 32 m² room. I tried both Teufel and Elac speakers.

I even used a different phone, a Samsung instead of a Vivo, and with both speakers and in both rooms, there was always a boost at 8 kHz, as you can see in the diagram!

How is that possible?

The 8kHz boost is because phone microphones are generally unreliable particularly at high frequencies. A USB mic like the imm6c or UMIK-1 is preferred.
