Product Manuals

Q: How mahny watts?

A: KEF recommends 25-100 watts per channel to drive these. I bought the same stereo amps that KEF uses to demo them, the Parasound Halo A23, which runs about $1k. That amp is rated at 125 watts into 8 ohms. I wouldn't recommend using the KEF LS50s with anything less.

Get Them While You Still Can!
I now have three pairs. These are awesome speakers. I’ve been searching for a 3rd pair for a while and was happily surprised when Best Buy had them in stock in Matte Black and new! I also have a pair or the KEF R3 and those are definitely better overall. However the R3 are huge for bookshelf speakers. They do give off much better bass though. The LS50s are great for near field or smaller rooms. They sound much better with a subwoofer. Completely changes the sound stage. I’ve paired them with KC62 and it’s definitely a step up. The build and look are unmatched. Grab them while you can. Especially at clearance price!

Sound great, but demanding power requirements
I'm downsizing, and bought these as a more compact replacement for some classic KEF Reference 104/2 speakers from the 80s. I'm using the Sonos AMP as the amplifier/music streamer, which provides 125W/channel of Class D power, which is taking the place of my older 100W/channel ADCOM GFA-545. The LS50s are actually more demanding in terms of power than the 104/2 speakers; the Sonos AMP drives the 104/2s nicely, but with the LS50s, it struggles to make a clear distinction between forte and mezzo forte, indicating that it just can't deliver enough juice to make the speakers happy. The ADCOM GFA-545 did better powering the LS50s in that respect, probably due to its substantially beefier power supply. Lack of sensitivity is a common complaint about the LS50s, and I can say that the issue is real. You need to be able to give them MOUNTAINS of power to get the best performance. That said, the LS50s are super neutral and clean-sounding; the imaging is good, and for their size, I haven't heard anything that sounded even close to them. Their low-end can be a little weak; it helps to use a subwoofer with them if you need room-shaking bass (or to hear the Moog Taurus bass pedals on your famous prog rock album) but it's not strictly necessary.
