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 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.

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.

Hello everyone, I would like to use the aux imput with a DAC. Is it possible to use the auxiliary input with FLAC 24 bits / 96 or 192 kHz ? Is there a digital processing on the input auxiliary ?

Asked by: fanfan
Yes, It is possible to use the AUX input on the L8 with a DAC, regardless of what the format of the digital input was at the time it entered the DAC.

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
The light is flashing, so it is receiving power. Even so, it is a long shot, but please try connecting it to a different wall outlet, just to confirm the problem is with the L8, and not with your electricity. If this does not solve your problem, and being that a reset is not possible, please submit a case on our JBL website to provide warranty options. Website: https://www.jbl.com/support-warranty.html.

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.

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.
