## Customer Reviews

### ⭐⭐⭐⭐⭐ GREAT SPEAKERS
*by  on Reviewed in the United States August 18, 2026*

These are great! They are actually motorcycle speakers but I put them on my ATV! Very good quality and loud! They come with a volume knob that works great! I would recommend these!

### ⭐⭐⭐⭐⭐ Best bang for buck
*by  on Reviewed in the United States August 28, 2026*

These work amazing use them on my dual sports and adventure bike super loud and clear audio . They do not carry bass well at all and will sound distorted if you don't set the eq to low gas or high vocal or manual decrease the bass in settings but mids and highs with a little bass phenomenal . You can hear clearly over the wind on the road but can get muffled if exhaust is too loud or wind too high . Side not went out at one point and vendor sent a replacement with ease under warranty .

### ⭐⭐⭐⭐⭐ Good system for a good price
*by  on Reviewed in the United States April 24, 2022*

EDIT 5/19/23:Over a year later and these are still functioning exactly the same as when I installed them. The sound and volume remain the same, as well as the speed of connecting to my phone. All wiring and physical connections are good. No issues. Still 5 stars for me.ORIGINAL REVIEW 4/22/23:I'm not sure if other reviewers received a different unit, but the one I got is great. The one I received had an inline fuse and power switch, and seems to be robust, although I've only riden with them for two days, so time will tell and I'll update this review if anything changes.The installation is very simple, and I was glad to see that the speakers fit on my risers and nested pretty well in the speedo and tach humps in my t sport fairing on my fx softail. Like I said, I'm not sure if other reviewers received a different unit, but this one is plenty loud at 70mph with my 96in motor and short shots. In fact I don't need to turn it up all the way to clearly hear it, maybe 75%.The sound is fairly flat eq wise, and at lower speeds it has okay bass, but the limiting factor is the size of the cones. But here's the thing, when riding a bike, your ear has trouble hearing bass frequencies anyway, and the loudest sounds will be mid-high. It's not that the unit is bright on the top end rather that the signature is flat, and higher frequencies can be piercing at high volume depending on the track, but I don't find it fatiguing if the volume is adjusted accordingly.I think these speakers are a good value for the cost and sound, I'm happy with my purchase, and I'm glad I bought these over the cheaper options.
