Rated 5 out of 5 by from Totally blew me away... Got it this afternoon, unboxed it, powered it on, connected it through Bluetooth, started up Spotify on the IPhone 6Plus and... Well.. I've been listening for hours now.. It's like listening to music for the first time, hearing details never heard before, still I've heard the songs tens of times before.. And my god.. It surely plays loud if you don't want anyone else to be able to stay inside... I'm speechless. Astonished. The Best Buy ever. Go get one for yourself.

Rated 5 out of 5 by from Sound quality is amazing We have the JBL Authentics L8 in our home and not only is it LOUD but the sound quality is unbeatable! This was definitely worth it.

Rated 5 out of 5 by from Absolutely amazing system! I bought this product 4 months ago and have to say, it's the best money I've ever spent. The sound is ridiculous! When I have company, it usually takes my guests less than two minutes before they comment on the amazing clarity and bass. There has been times where it goes in and out while utilizing AirPlay. I've chalked it up to my router. If you're looking for a speaker that can fill a large room - this is it. I live in a flat that has a common area of about 700 square ft. It has absolutely no problem filling that space perfectly - at all volume levels. I will say, it doesn't sound nearly as good when playing music via bluetooth. If you're not going to use this with your wifi, not sure its worth the money - would be missing out on the true potential of the speaker. Craftsmanship of the unit is also pretty stellar. Nice solid/heavy construction.

Rated 5 out of 5 by from Outstanding clarity of music This is such a great sounding unit I'am using mostly Apple Air-Play and the details of the music beats my two speaker and sub system. It is like rediscovering my music collection and hearing details In the music I have been missing.

Rated 1 out of 5 by from DO NOT BUY I bought this unit April 2014. After just over 3 years of moderate usage the unit has failed due to what appears a software issue. It seems like a common fault having read other reviews- the source button flashes repeatedly and the unit is inoperable. As the warranty period is only 2 years I now have to send the unit off to be repaired at my own cost. NOT REALLY WHAT I EXPECT FOR A £600 PRODUCT.

Product Q&A

Hi there, could you please let me know if I were to get two of these could I use them simultaneously in different rooms like a multi room system? 

Asked by: Minoutje
You could also use 2 Audio Chromecasts to accomplish multi-room. They are cheap and do the job incredibly well.

Hi, One day when I switched my L8 authentic on, it started quick flashing non stop on the source button. Now I cannot switch it on, neither able to factory reset it nor able to install firmware. Can you suggest any diagnose?

Asked by: shankzone
I have the same problem and had an awful time getting somewhere that would look at it for repair. In the end it was eventually replaced and now less than a year with the new one and it is doing the same thing!! I want a replacement with another device this time as it fails too easily and there is little or no support for faulty units.

I love the sound for my L8 but recently when I am playing music over airplay, it loses signal often and fails to reconnect. I have go to the unit, turn it off and turn it back on to get it to reconnect. Any way to fix or diagnose?

Asked by: roctavio
What you are experiencing with your L8 is not normal. Since this is Airplay that you are having issues with, it can either be the L8 having issues, or the home wireless network. Please try to do a reset on both your router and the L8, redo the set-up and this should fix the issue. To restore the L8 to factory settings - In power ON mode, press and hold the Power Button for at least 10 seconds, until the volume and input selector lights begin to flash. Reset to factory default includes Source, Volume settings, EQ settings, AirPlay name and Wi-Fi settings.

Despite of automatic switching is mentioned in the specification, my optically connected TV can be selected manually only. That's a bug in my device or a general "feature"? I need a quick answer in order to replace it in time

Asked by: a zs
The auto switch function pertains to the App. You don't need to switch sources on the unit if you are using the App and you can switch to any source without having to cycle through them.
