About the Product
The LS50 monitor delivers a rich, multi-dimensional 'soundstage experience' that is out of all proportion to its size. Patent-pending acoustic designs, together with state-of-the-art technologies from KEF's latest flagship Blade loudspeaker, provide the ultimate studio experience - even in the smallest of spaces.
The Concept 20 represents the start of a new era going beyond anything that Q Acoustics had achieved before. It's a beautifully styled product, which we confidently believe provides a level of sonic performance previously thought impossible at its price point.

What customers say about "Size & Weight"
KEF LS 50 Studio Monitor Anniversary Model (Pair)
- My biggest impression was the high audio quality and sound quantity coming from a few compact sized speakers.
- These speakers are built exceptionally well. They're fairly compact compared to other bookshelf speakers.
- Ideal size for apartments and more than enough power to fill even big rooms with excellent sound quality.
- First impressions, even before you open the box, are that you're in for something special that they weigh a ton!
- A driver this size simply can’t drive enough sound to fill a medium to large room satisfactorily. And they are heavy enough for such a small size.
Q Acoustics Concept 20 Bookshelf Speakers (Pair) (Gloss Black)
- Unbelievable sound for the size and price - bought also the specific stands and I have a sound comparable to much more expensive speakers.
- Excellent sound. They look fantastic in my living room. Great size for a small room.
- A very articulate and open speaker, clear and refined, amazing for it's size.
- Compact size means fits smaller rooms. Quality reasonable for the price.
- I'm still amazed at how much sound comes out of the relatively small cabinets. But in fact, weight can cause inconvenience when installing them.

What customers say about "Audio"
KEF LS 50 Studio Monitor Anniversary Model (Pair)
- Amazing sound that’s crystal clear, with a terrific soundstage even when sitting near field.
- Having these on a desk is totally doable, and a pleasure to listen to. No fatigue, just beautiful sound. This is especially true for vocals.
- Very impressive natural sounding speakers. The detail and separation are superb for bookshelf speakers.
- There was nothing about them I liked at all, treble, midrange, bass and soundstage were all very weak.
- The only negative for me is when you take these off a desk, or out of a small room. The soundstage simply isn’t there, and that’s expected.
Q Acoustics Concept 20 Bookshelf Speakers (Pair) (Gloss Black)
- Absolutely fantastic sound! Just don't place these too near a wall as this makes the bass boomy.
- Bass was kicking through better with a well toned mid and crisp high range.
- These speakers handle it superbly right across the range and at a high volume. You won't be disappointed.
- The Q Acoustics concept 20 has clarity and detail as well as good bass and fantastic treble.
- Superb speakers, with the right gear, environment & setup properly, they sound better than speakers several times the price.

What customers say about "Features"
KEF LS 50 Studio Monitor Anniversary Model (Pair)
- Good-looking equipment, solidly-built, which has rejuvenated my hi-fi system.
- The design and the components have made these incredibly good. These speakers are very neutral and truthful.
- These are beautifully crafted, incredible sounding entry-to-mid level audiophile speakers.
- They are beautiful, solid, and they deliver and incredibly deep and powerful sound.
- Very nice speakers with a neutral, forward sound. The frequency response is nice and tidy, and they got much louder than they would appear they could.
Q Acoustics Concept 20 Bookshelf Speakers (Pair) (Gloss Black)
- Right out of the box, I was very excited to hear these speakers in action everything I love about a speaker.
- In speaker was present effortless imaging, clarity and transparency and they don't skimp on bass either.
- Really nice speakers, bit larger than my other Q Acoustic bookshelf speakers, play with the port bungs to get the perfect setup.
- The bass is surprisingly good. I connected the speakers to a Yamaha AS-301 amp and everything worked great.
- They sound and look great, come well packaged with clear instructions. Would absolutely recommend.
