Tannoy Gold 5

Things have really changed in recent years! There was a time when you had to pay three or four times as much to get this kind of sound quality. As an old-timer I'm pretty astonished at just how good these monitors are, considering the extremely affordable price.
They basically only have two weaknesses worth mentioning: the bass is nice and deep enough for any music that isn't extremely bass heavy, but the lowest bass is missing since it's just a 5" speaker, and the treble is slightly lacking in clarity.
But the essential midrange is flat and revealing, and the coaxial design gives excellent imaging and produces a sound that "holds together" even when you move around, making you feel less glued to the sweet spot while mixing. Some people don't really care about this, but to me it gives a more relaxed experience working with coaxial monitors.
Human voices come through especially clear with this monitor, and appear to come from an exact spot between the speakers. Very nice!
Two little friendly design choices I want to mention are (1) you can feed an aux signal from a phone or iPad into them without disconnecting your audio interface, and (2) there's a switch on the backside to enable or disable automatic standby.
PS. There's a gain knob on the front that could as well be glued in the minimum position, an audio interface produces a strong enough signal without any extra help.
EDIT
I wanted to add that these speakers have a quality that is very desirable for a studio monitor, which is that good mixes sound amazing, whereas a problematic mix isn't given any mercy. They are also engaging and satisfying to listen to at low levels, so you aren't tempted to raise the volume, which helps preventing listening fatigue. In short, these are some excellent studio monitors!
There are actually *two* studios in my home, because both my wife and I make music! I have a pair of Kali Audio IN-5 in my studio, these Tannoys were bought as an upgrade for my wife's studio to replace her old monitors. The Kali monitors are very good, and I've been very happy with them, but they have a somewhat muddy lower midrange because of resonances in the thin enclosure. The Tannoys are better than the Kalis, with a much greater clarity in the midrange. So now I'm envious!

I moved to Berlin for work and I missed my home studio setup, which I couldn't bring with me. I didn't want to spend a lot, but wanted something adequate for music listening and fiddling with Ableton Live in an apartment. For the price? Absolutely amazing. I had all sorts of cheap and good monitors in my life, but these tannoy are really impressive. Even without sub they are capable of reproducing a fair amount of bass given the size of the speaker, without ever being unpleasant or undefined in the lowest range. Obviously they cannot reproduce sub frequencies: they start a gentle rolloff at 70Hz, but they're perfectly adequate for most situations other than heavy electronic music or film scoring. Also the staging is very good and I'm perfectly capable of distinguish the position and the distance of every instrument in the mix. The frequency response is good at near field listening levels, and I don't feel like the dynamics are too compressed. Keep in mind though, that these speakers are very sensitive and they do not have an input level padding switch. For this reason if you connect them directly to certain sound cards you'll find that they are very loud, even with the volume knob at 0, it depends on your card output level. Solution? Use a mixer in between or a passive attenuator. I had to pair them with a couple of JTS MA-123 (also bought on thomann) to preserve audio resolution of my sound card. With the attenuators they are killer for a home or portable recording/mixing setup.

Testing them 3 days in the row. Sound is near perfect. Bass ohhh, very good, you can even touch it. Well made, when you take them in your hand, you will understand that this speakers is something from great quality product. Also very happy about Aux, because I can connect my laptop, and my mixer to them at the same time. When I am mixing, use balanced XLR input, when watching for example movie use AUX. And there look, is very impressive. All my friends, is speaking about them. Luxury stuff, for such money. Sound overall is very good.

These monitors are very pleasant not only to work on but also to listen to music. The overall frequency response is quite flat. As you can expect from a speaker of this size, low-end is not it's strong suit, instead the mid-range is very revealing and forward sounding and the higher frequencies aren't at all harsh. If you are looking for monitors to mix on, I would definitely recommend these. I've only had them for a few days and am really enjoying them. The bass and treble controls allow for greater flexibility in their use. Set them up, measure their response in your room, then EQ them with Sonarworks or REW, and you're quickly in business.
