What customers say about "Size & Weight"
Elac Navis ARB51-GB Premium Powered Bookshelf Speakers - (Pair) Gloss Black
  • Pleased! These speakers are solid and have weight to them.
  • What makes these small bookshelf speaker impressive is the sound stage, it is absolutely great! There presence is very, very pleasing.
  • Replacing Dali 102 they are 2/3 the size and twice the weight.
  • Grab it especially when it's on sale. To get the potential out of these little monster speakers, feed it with enough power and good music source.
  • I can't believe so much sound comes out of this little speakers, is unbelievable and at the price they are going for is a bargain.
KEF LS50W Wireless Powered Music System (White, Pair)
  • The little KEF is incredibly articulate, detailed, images well, but is never strident.
  • I wanted to upgrade my sound system in my computer room. These little gems have worked perfectly.
  • I'm blown away by how much and how good the sound that comes out of these little speakers is!
  • These are perfect for anyone looking to create a small (but with big sound) 2.0 or 2.1 system for a small to medium space!
  • I don’t see how anyone could be disappointed by the bass response of this speaker on its own; it really is exceptional for such a small cabinet.

What customers say about "Audio"
Elac Navis ARB51-GB Premium Powered Bookshelf Speakers - (Pair) Gloss Black
  • The sound stage is vast and musically punchy but with great clarity. A real delight especially for the price.
  • Great speakers that sound much larger than they have a right to.
  • In terms of what I can tell you about the sound, I can say that the fawning reviews are not hype or groupthink, but pretty accurate.
  • These will probably sound good with cheap amps/receivers. Midrange is good.
  • Small room, small budget, but big, beautiful sound.
KEF LS50W Wireless Powered Music System (White, Pair)
  • They produce a wonderful image and are very musical and detailed.
  • The amplification and DAC portions perform very well. They play loud and don't get too strained while doing so.
  • They produce very tight and musical bass that is well-integrated into the speakers' overall voice.
  • These speakers play cleanly and maintain their focus and tonal balance up to very high volume levels.
  • The sound is well-balanced and has dynamic punch.

What customers say about "Features"
Elac Navis ARB51-GB Premium Powered Bookshelf Speakers - (Pair) Gloss Black
  • Exceedingly happy with this purchase as a nearfield setup at the computer. They sound and look great.
  • They deliver a very coherent sound with a nice, wide, and focused soundstage freeing the music from the confines of its sturdy enclosures.
  • Detailed sound, good quality and well made speakers. Nice design and pure sound.
  • Amazing design, very good sound, awesome price. I’d definitely recommend them.
  • The quality of sound emitted by these diminutive speakers is just amazing.
KEF LS50W Wireless Powered Music System (White, Pair)
  • They look like art work... I have them on Dynaudio Stands. Jesus Christ the sound is amazing.
  • They sound amazing. Look fantastic. Have every feature you could ask for.
  • The coaxial design also makes you experience the music as truly one piece, and the speakers stay incredibly clear and strong at lower volumes.
  • The biggest fly in the ointment here is the not ready for prime time app that runs (in my case) on Android to control the speakers.
  • Some things can only be controlled by the app, some only the remote. Not the best solution.
