Loud Clear Wireless Sound Anywhere You Want It

Our most popular model, loud clear sound with huge bass in a more portable package size than our XL3

Wireless True Stereo Sound.  Dual 8.5" DVC woofers and 4" bass port for bass you can feel as well as hear.  120dB loud. Anywhere, anytime, no electricity needed.

With its built-in 6 channel Class A/B hi-fi 300 Watt RMS (600W Max) amplifier in a tri-amped arrangement with active crossovers it provides the best sound possible in the lightest package with the longest battery life. 

With its massive aluminum front panel serving as the amplifier's heatsink, it is made to play FULL BLAST all day on a hot day without skipping a beat.  The included big and lightweight 231Wh battery can play music for up to 26 hours and it can play while charging for indefinite playtime. 

The L3 is the biggest value in our lineup and for most people it is more than enough sound to get in trouble with your neighbors.  Search youtube for many independent reviews.

Turn heads and drop jaws while you play this at obnoxiously loud volumes with a fidelity people didn’t know they needed till they hear this speaker.

Probably sold three+ speakers at the first party I brought this to.

What hasn't already been said about the L3?

Beautiful looking and just amazing sounding speakers! Robust build, extremely clean, 100% blemish free. Love the Panda finish. As a stand alone, one L3 is you will ever need. So of course I bought two, and together it's just other worldly. Can't wait for my pair of XX4s to arrive!!
