JBL's Xtreme 4 Bluetooth speaker has two tweeters and two woofers to deliver crisp highs and detailed midrange. Dual side-firing passive radiators help this portable powerhouse kick out strong, solid bass.

When you're connected to AC power, the speaker's built-in amplifiers run at 100 watts total power for maximum volume and clarity. When you're outside using the battery, it operates at 70 watts to deliver big sound for hours on end.

The Xtreme 4 is completely waterproof and dustproof. So take it to the beach, to the slopes, and any place in between. The built-in rechargeable battery delivers up to 24 hours of operation. And if that's not enough, the Playtime Boost button optimizes performance to give you up to six hours of additional battery life. And the battery pack's removable, so you can replace it down the road to get your speaker back to full power. (Replacement battery pack sold separately.)
