## Customer Reviews

### ⭐⭐⭐⭐⭐ Add some bass to your box
*by J***N on January 6, 2026*

I needed a little more thump from my small speaker box and this was the ticket. Definitely helped the sound quality.

### ⭐⭐⭐⭐⭐ Works great
*by J***L on July 28, 2025*



### ⭐⭐⭐⭐⭐ perfect for diy bluetooth speaker box builds that utilize a dedicated subwoofer
*by J***N on November 19, 2025*

A bit pricey but it definitely gets the job done with a sealed enclosure. I use these for diy bluetooth speaker box builds that have a dedicated subwoofer.
