Throughout history, people have equated light with spirit or soul. We here at Altec Lansing feel the same way, so we created the LIGHTNING speaker. We started with the same formula that Altec Lansing is famous for - incredible audio engineering and robust drivers combined with state of the art amplification. LIGHTNING pumps an incredible 2,200 watts of power through its massive 15" high excursion woofer and 3.5" horn tweeter. Then we added the features we know our customers need. LIGHTNING packs Bluetooth streaming and stereo pairing, so you can even create a wireless stereo pair with another LIGHTNING speaker. It has a built-in Media Player with support for playing music from your USB drives or SD cards plus, the FM radio is perfect for tailgating or the beach. Plus, the full audio mixer gives you the inputs and outputs you need to turn any place into your private concert venue! If we stopped right there, that would be enough - but we are not finished. We needed to give LIGHTNING some soul. So, we created a dynamic, multi color light show for the front of the speaker that will do everything from setting a subtle mood to recreating your favorite dance club! The user controllable lighting can flash and change colors to the beat of the music, glow or pulse in a single color, or turn completely off. It is up to you.
