About the SoundExtreme SEB26

20 hours of musical power
20 hours of musical power
The battery-powered SoundExtreme SEB26 packs a ton of nifty features into a lightweight, compact sound bar that's ready for fun on land or sea. This 26" outdoor-ready sound bar sports eight marine-grade speakers (four midrange speakers, two side-mounted woofers, and two tweeters) powered by a Class D amplifier. The rechargeable 12-volt Lithium-ion battery pack gives you up to 20 hours of play time at normal volume and an equally impressive four hours when it's cranked up to max power. Installation's a lot easier, too, since you don't have to wire it to your vehicle's battery.

Cool, colorful lighting
Speaking of lighting, the SoundExtreme SEB26 features multi-color LED backlighting in the mids and woofers. You can select red, green, white, or blue, and set them to glow in one solid pattern or a blinking pattern. There's also a rear-facing multi-color LED light that can be turned on separately from the speaker lights. This light can be synced to your music, blink, or glow steady.
Convenient controls
You can use this sound bar's built-in Bluetooth to listen to your favorite music apps or stored tunes streamed from your smartphone. And you don't have to be sitting in the cockpit to control your tunes because Bluetooth 5.0 provides a reliable long-range connection from your smartphone to the sound bar. There's a built-in microphone for phone calls, plus easy-to-operate (even with gloves) controls on the bar itself. The package also includes a wireless remote that will control both the audio and the lighting. You can also use the built-in EcoTalk feature to activate the voice assistant on your device (Siri, OK Google, etc.) when you're in Bluetooth mode.
Built for the trail
Outdoor life can be tough on equipment, but this IP66-rated sound bar is built to handle dirt, dust, and water, with a rugged housing, stainless-steel hardware, and durable, waterproof connections. The package includes mounting brackets and integrated, threaded mounting holes for a variety of mounting options on off-road vehicles, boats, and even golf carts.
Invite some friends
The SoundExtreme SEB26 includes the nifty EcoCast technology, which will let you connect to any SoundExtreme speaker with the EcoCast feature. You can daisy-chain up to 50 of their sound bars and subs, so heck, invite your friends, their friends, and even friends-of-friends-of friends.
Add a sub and boost your bass
If you're craving more bass thump, add on the ExtremeSub ES08 subwoofer. It connects wirelessly to your SoundExtreme soundbar and offers the same outdoor-ready durability you expect from EcoXgear products.

Features
Overview: The SoundExtreme SEB26 is an all-in-one sound system with an integrated RGB LED lighting system that's designed for ATVs, off-road vehicles, marine craft, and golf carts. It includes a built-in 500 watt Class-D amplifier that powers 8 marine-grade speakers in a durable, weather-resistant enclosure. It also features Bluetooth connectivity for audio streaming, a USB charging port, FM tuner, and a 3.5mm (1/8") stereo Aux input. The SoundExtreme SEB26 includes a rechargeable Lithium-ion battery pack that offers over 20 hours of playback time on a full charge.
Speaker Array: Eight marine-grade drivers are included in the SoundExtreme SEB26: four 2.25" midranges, two 1" tweeters (all front-firing) along with two 4" woofers - one on each end of the speaker bar.
500W Max Power: The SoundExtreme SEB26 employs a 500W (Peak) Class-D amplifier for loud, dynamic sound performance that can be heard out in the open field or over the open water.
Built-In Bluetooth: The SoundExtreme SEB26 offers built-in Bluetooth 5.0 for hands-free communication (HFP) and wireless audio streaming with control (A2DP/AVRCP). You can pair and connect one device at a time. If your already-paired device comes within range of the Party Bar, the two will automatically reconnect.
- Hands-Free Communication: The soundbar features a built-in microphone and lets you answer/end calls that are incoming from your Bluetooth-enabled smartphone. The caller's voice is heard through the soundbar speaker, while you talk into the soundbar's built-in mic. You will still need to use your smartphone to make a call and then the call will be transferred to the soundbar speaker system.
- Wireless Audio Streaming: You can also wirelessly stream stored music and music apps from your Bluetooth enabled source device (like a smartphone or tablet) to the SoundExtreme SEB26. You can even control music playback functions like Volume up/down, Play/Pause, and Previous/Next Track from the included remote control. Advanced music navigation and song/artist information must still be done on your Bluetooth enabled smartphone or tablet.
Aux Input/Output: In addition to wireless Bluetooth connectivity, the SoundExtreme SEB26 is equipped with a 3.5mm Aux input for connecting a portable audio source with an audio or headphone output. An additional 3.5mm Aux Output port is provided for daisy-chaining the signal to additional soundbars. Both ports have waterproof rubber caps.
USB: The SoundExtreme SEB26 includes a front-panel USB port (type-A, 2.0) that can provide a 5V/2.1A output for charging portable devices, and includes a waterproof rubber cap.
Note: The built-in USB port is for device charging only and does not support audio playback.
FM Radio: A built-in FM tuner lets you tune in FM stations. Right and left arrow buttons let you scan for the next available FM station. Two FM Presets can be stored in the soundbar. When a station is tuned in, pressing and holding the Bluetooth button will store the station as Preset 1. Pressing and holding the Play/Pause button will store a station as Preset 2.
Integrated RGB LEDs: The SoundExtreme SEB26 features a built-in RGB LED illumination system with back-lit midrange speakers, both end-mounted woofers, and an LED light bar running along the rear panel of the soundbar. The speaker LEDs have 6 available Party Light Modes: Red Light, Green Light, White Light, Blue Light, Music Sync, and Fading (slowly cycles through multiple colors). The rear facing LED light bar can be operated independently from the speaker LEDs and includes 5 Light Modes: Red Light, Yellow Light, White (High) Light, White (Mid) Light, and White (Low) Light. The rear light bar can also be synced to the music or lit solid. Both the front and rear LEDs can be operated from the included hand-held remote or the front panel controls.
Front Panel Controls: Control for the SoundExtreme SEB26 can done right from the front of the unit. Weather-proof rubber buttons are provided for Power, Bluetooth (pairing), Volume Up/Down, Fwd & Back Arrows, Play/Pause, and Mode (changes the listening source between Bluetooth, FM, and Aux-in). Two LED buttons let you independently activate the front and end-mounted LEDs. Along with the controls, the front panel includes 4 LED indicators that will light to indicate Power, Bluetooth, Mode, and Status.
EcoCast: EcoCast technology lets you increase the size of the party by letting you connect multiple EcoCast-equipped speakers (up to 50) to one SoundExtreme EcoCast speaker when using Bluetooth Audio as the sound source. The playback speaker can then broadcast its Bluetooth Audio to the other speakers, with a range of up to 30 feet. Two EcoCast modes can be selected from the front panel or the remote control: EcoCast Transmitter and EcoCast Receiver.
EcoTalk: Pressing and holding the Play/Pause button lets you activate the voice assistant on your device (Siri, OK Google, etc.) when in Bluetooth mode. When activated, the microphone on the soundbar will pick up your voice commands and transfer them to the voice assistant on your device.
Remote Control: The SoundExtreme SEB26 comes with a hand-held RF remote control for wireless operation of the soundbar speaker. The included RF remote will let you wirelessly control Power On/Off, as well as cycle through Bluetooth, EcoCast Transmitting, EcoCast Receiving, FM, and Aux-In sources. The remote also gives you control of the RGB LED lighting.
Mounting Options: The SoundExtreme SEB26 includes universal L-mount brackets for surface mounting the soundbar speaker, allowing it to be mounted on top of or suspended from a flat surface. 3" and 2-1/2" worm clamps are also included for mounting to roll-bars, waketowers, or cage tubing.

Super pleased, easy to use, wish it had better hardware for off-road install, it's just rough where I spend my time. Sure it could have more bass, but my time is spent on the trail, not partying. Heavy duty
