What customers say about "Size & Weight"
KEF Q150 Bookshelf Speakers (Pair, Black)

  • They are small and they are basic and lightweight overall.
  • They are bigger than they look because these speakers are very deep.
  • These speakers are much bigger than I had in mind. They're too big to be used as desktop computer speakers which is what I bought them for.

What customers say about "Audio"
KEF Q150 Bookshelf Speakers (Pair, Black)
  • I was actually surprised at how good these speakers sounded. The sound quality is impressive. They sound very clear. The highs sound perfect.
  • The speakers are rear force and distance to the wall behind is a determining factor in the lowland sound. The mid-range and highs are excellent.
  • The highs are crisp and crystal clear. The mids are clear and warm. Then there's the bass.
  • The sound if very clear through the whole spectrum with the sweet spot in the upper mids. Soundstage and imaging are fantastic and doesn't sound overly bright.
  • It lacks deep bass and really doesn't handle them well.
KEF Q350 Bookshelf Speakers (Pair, Black)
  • Sounds extremely clear. Highs and mids are smooth and rich.
  • I'm very pleased with this purchase. The sound is better than I thought.
  • These speakers are so crisp! Great lows, mids, and highs.
  • For small bookshelf speakers, they deliver wide deep bass, smooth sound from top to bottom.

What customers say about "Features"
KEF Q150 Bookshelf Speakers (Pair, Black)
  • The perfectly sharp edges and aluminum woofer give it an elegant and modern look.
  • The woofer is assembled perfectly and looks sophisticated with the aluminum material and waveguides.
  • You'll be very pleased with their performance for most types of music - classical to vocal to techno, they have a fast, dynamic sound and are very revealing with source material.
  • Terminals on the back seem solid and they come with foam cutouts to put in the ports if you’re looking to scale the bass back.
  • The build quality of these is nice. I like them better than the Elac's, which isn't as smooth. They are made out similar vinyl finish.
