**Q: Why do the 2 side views differ so much?  One looks much larger / deeper than the other.**
A: Looks like the last picture is of the 6 1/2” speaker, not 6x9

**Q: Do they have led lights?**
A: Mine dont

**Q: Is this a pair of speakers or one.**
A: Pair

## Customer Reviews

### ⭐⭐⭐⭐⭐ Crisp sound with decent bass
*by A***R on July 28, 2021*

Im happy with em, 4 of the 6x9 s in my boat sound good . Blasting these may be hard on em but out of the box sound quality is really good . I am pleased this far with my purchase

### ⭐⭐⭐⭐⭐ Fantastic
*by B***3 on July 1, 2021*

Put 4 in a 21’ bay boat. No amplifier, loudest cleanest marine speakers on the market if you’re not looking to spend a fortune. No problem hearing them over the motor and wind.

### ⭐⭐⭐ Don't waste hard earned money
*by F***5 on July 26, 2025*

Save your money! They lasted 2 seasons and stopped working. Just enough to be out of warranty. Good while they worked but didn't last long.Not a great value for the money being spent.
