Review: Good for the price - Sound good for the size not crazy bass but gets the job done for my application✅
Review: Does more with less power - Don’t expect to have any crazy base from a small 4 inch speaker but it’s does what it’s supposed to do. A lot better than stock audio. Doesn’t cut out at higher volumes like the stock speakers do and has a great range of sound. They do more with the same amount of power stock speakers do and the cover looks great in my bmw e92. BMW tries to stop you from really changing these things by changing up the wiring and all that and being weird with figment but once I got it into the right spot it was pretty easy to install and fit perfectly. I still have to upgrade the rear speakers but the front end is perfect now.

### ⭐⭐⭐⭐ I'm very impressed
*by D***H on June 2, 2024*

These are very good sounding speakers. I've been using them for a few months now and they are impressive. Huge sound for the price. I'm interested in finding out how good the larger speakers will sound. I bought these with my own money and I'm not paid for my review.
