The sound is great and the lights are a nice touch!
Great soundbars. Support team is very accommodating!
Solid build and great sound quality.
The dealer led me to buy this and a sub. I’m disappointed especially for the cost. Not as loud as I thought it would be and the sound isn’t right.

This thing is a beast. Shipped so quick I didn’t have my cart ready for installation. I would recommend the rechargeable battery type. No wires to fuss with and blowing fuses.
This item works great, very loud and does exactly what I wanted. I have not tested it in in the woods yet, but as for testing it I like it. I have the SEDS32" on my other sxs and love it too !! Very pleased!! Definitely recommend this sound bar . Definitely worth the money and is a 5 star for me.

Five stars
Very disappointed in the sound, thought this would be louder then the 28 but it is not. The mounting options suck the old style was far more superior in being able to angle the speaker.
Speaker is to high pitched. To much treble. Hurts my ears. I can only play it on low volume. No bass at all. I regret buying this speaker
I bought se33 and woofer for my golf cart and had it professionally installed. Worked great then the lights stopped working on the soundbar . Took it back to installer replaced it with another one , this one has multiple problems. When it turns on music cuts in and out speeds up like it’s trying to catch up to the woofer, can’t control sound from my iPhone, sometimes the buttons on the soundbar don’t work . This is all on ECOGEAR setting when you switch to ecocast soundbar works fine but you can not connect to woofer and iPhone doesn’t connect automatically you have to go into Bluetooth everytime . Customer service is horrible I have called at least 5 times and emailing one guy for over 5 days . Buy a different brand!!!!!!
I bought this speaker with high hopes. The lights were nice and the sound was ok. In less than a year the speaker stopped working. I contacted the customer service and they would not even look at it. They said that I had damaged it and it would not need to look at it. I don’t know how they came to the conclusion that it was damaged and not a workmanship problem with out ever looking into it . Save your money and buy some tower speakers.
From the start this product has been nothing but a disappointment. The **** holes were not lined up correctly out the box so I had to use a hammer to knock it into place. Then once the difficult installation process was done, it sounds scratchy. Almost like a speaker blew from less than an hour of music play. Hopefully this brand will make it right. I’ve owned their speakers for years and never had issues, but this is making me think differently. I would not recommend this product. It’s not worth the money
Steady and quality. Also looks really cool.
Love this speaker! Wish it would’ve come with the attachments and didn’t have to purchase separately but it has amazing sound and it so easy to use!
This speaker system is so nice without the need to run wires....My ECOXGEAR SEB26 is mounted under the roof and in front of the front passenger/driver with the help of a bracket that fits my Club Car Precedent... One thing I didn't know until I received this unit is that it has a built in FM Radio.....this comes directly from the speaker and not the bluetooth connection of the phone....It works well, without a need for an external antenna..... Also having an additional light bar just under the roof, facing oncoming traffic creates extra safety.
The plus: build quality is great and they've seemed to put a lot time and effort into the LED options and programming.
The minus: There is no equalizer functions to adjust sound. It tends to be high in the treble side with no internal adjustment features.
The power cord is short.
For the cost of the unit you should have full control of sound output and a long enough power cord to install it anywhere on a sxs.
has anyone hooked this up to a wired sub? Their 8" sub wont fit in my machine. I want to get a powered sub but not sure on install
Hello! Please reach out to us at support@ecoxgear.com and we can help you with this request on a subwoofer install.
Perfect for both my boat and Jeep, this battery-powered soundbar delivers solid sound without needing a power hookup. It's rugged, weather-resistant, and holds a charge for hours—great for off-grid adventures. Bluetooth pairs quickly, and the audio stays clear even at higher volumes. It’s a must-have for anyone who wants portable, hassle-free sound on the water or the trail.
Thank you for the great review!
I received this speaker as a gift from my children for my birthday/Fathers Day. The speaker itself was very easy to install (made a template so we did not have to hold the speaker up to mark the holes for drilling), It was installed on a custom golf car so running the wires took about 15 minutes and had to add some wire to make it to the battery. Instructions were great and very easy to understand. Turned it on, turned it up and the whole neighborhood got to listen to Joan Jett's song "I Love Rock and Roll". Great speaker - best one that i have used in a long time in this type of application.
Best speaker yet and thanks for the orange stickers I appreciate it
Love the soundbar and the elaborate lighting patterns!! Sounds awesome, hope the subwoofers hold up better than the old soundbar
Thank you for the review, Brian! Play it loud!
Great sound. Mounted on X3 with a loud exhaust and can still hear it just fine. Might purchase one for my YJ rock crawler.
It's a great product. Quality, quality, quality. Such a nice change to buy something that comes with excellent instructions, every part you need, and the confidence that if there is an unexpected glitch that the company will step up. You get what you pay for!
Thank you for the review!
Love this soundbar. The lights and speakers are awesome. Plenty loud to hear on my sxs going 45mph. Definitely recommend.
This is my second. Works awesome as a team wirelessly.
Sound bar has great sound! Installed on a golf cart.
Can not get the aux out to connect to my aux in on golf cart to play my speakers simultaneously with soundbar. Plus you can only charge and not playthrough USB. The sSE26 was much better it does all the things that SEB doesn't. Plus it had RCA outlets for easy connection to my golf cart speakers
I love the soundbar. I'd give it 5 stars but for one serious, but fixable, flaw. It is advertised as being compatible with many vehicles including my Polaris Ranger. However it cannot handle the voltage level of the ranger when the engine is running (~14.2 or 14.3 volts). The soundbar would simply turn off when the vehicle was started or when accelerating. Tech support suggested getting a voltage regulator, which I did, and all is well. But for $400 and when claiming support for this vehicle, the soundbar should have this built in and not require a separate $50 regulator.
sound bar worked great on day 1. Day 2 and beyond the bluetooth will not connect and the sound bar turns itself off. Emailed the link provided for support and have not gotten a response (3 days). DO NOT BUY. Support is terrible
