Here's Altec Lansing's largest, loudest, portable Bluetooth speaker-the ALP-XP800 Xpedition 8 Portable Waterproof Bluetooth Indoor/Outdoor Speaker! It features dual 8 in. woofers and three 1 in. tweeters that are powered by 420 watts of peak power. Customize your sound how you want to hear it because the Xpedition 8 can disperse sound whether standing upright or laying on its side due to its intelligent stereo orientation. Further, you can add sound by linking a second Xpedition to create a stereo pair! The IP67 rated speaker is dustproof and waterproof. The speaker can even withstand 3-28/100 in. of water for up to 30 minutes! The Xpedition 8 is the biggest, loudest, and best sounding portable IP67 speaker that actually floats, plus it's not heavy for its size and has integrated handles making it easy to carry. The speaker is designed to float in a position where the woofers and tweeters do not hit the water, so the sound is just as good in the water as it is on land! The Xpedition's LED light show features 12 color combinations from the woofers plus two strobe lights that will dance along with your favorite songs! This makes the Altec Lansing Xpedition 8 perfect for tailgating, parties or any time or place that calls for major sound.
