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
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.

Size misleading but Great sound
Leaving 3 stars only for misleading size. These are listed as 4” speakers and do not fit the enclosure i have that had another brand of 4” speakers. Thought it would be an easy seap and an upgrade since i have heard great things about CT sounds. Speakers themselves are great and have have good craftsmanship and sound quality just wish i could use them for my intended application.
