LS 50
About the Product
The KEF R300 Bookshelf Speaker is the larger of the two bookshelf speakers offered in our R Series, and with more size comes more sound. The R300 features a 5 inch Uni-Q driver array with a 1 inch aluminum dome tweeter at its acoustic center.
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.

What customers say about "Size & Weight"
KEF R300 Bookshelf Loudspeaker - Gloss White (Pair)
  • Love these speakers. Crystal clear mids and lows. Clean bass. Very pleased with its size.
  • Lows and mids are great. I was surprised that such small speaker can sound so excellent.
  • They are solid, well constructed and modern looking. And they are quite compact in size.
  • They are beautiful and solid. Compact and lightweight. Very smooth, easy to listen to for long periods of time, and has serious bass for a bookshelf.
  • This is larger and heavier than expected but quickly got used to it.

What customers say about "Audio"
KEF R300 Bookshelf Loudspeaker - Gloss White (Pair)
  • Outstanding sound. Well balanced. I am partial to a good mid-range and these do not disappoint.
  • Piano music makes you feel like you are in the hall. Great speaker even at low volumes.
  • For a small package these speakers really produce great sound covering excellent highs to bass.
  • The Kef at high volume shines! Appropriate bass response with crisp, but not harsh highs.
  • It sounds great. Definitely a better choice for me. I was also considering LS50's, but after listening to both I chose this due to better bass output and warmer overall sound.

What customers say about "Features"
KEF R300 Bookshelf Loudspeaker - Gloss White (Pair)
  • I use these strictly for music in a smaller space. Well built, excellent quality.
  • Finish quality is great. They come with a front screen, but look great with out it.
  • Great build quality. Hefty price tag but well worth the investment in my opinion.
  • The best speakers I have ever owned. Very wide soundstage, Crystal clear/detailed sound and awesome for movies, tv, and music alike. Will keep for life!
  • They're powerful enough. Well made cabinets. I use them with grills off - the chrome surrounds around the speaker cones look very classy.
