Great sound for a 4-inch speaker!
Iโve used these 4-inch CT Sounds speakers in a custom speaker box I built, and Iโm honestly impressed with how good they sound for their size. They have clear highs and mids with a surprising amount of punch when paired with a good amp and subwoofer. Theyโre also a great size when youโre trying to build something compact without sacrificing sound quality. Definitely happy with these and would buy them again for another build

Top of the line speakers without breaking the bank.
Perfect all around audio.

In combo with a crossover, these are great.
these sound great. I added a bass blocking crossover because these make crackle sounds with any bass .

Does more with less power
Donโt expect to have any crazy base from a small 4 inch speaker but itโs does what itโs supposed to do. A lot better than stock audio. Doesnโt 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.

Great speakers at an affordable price point
Got these speakers to replace my door speakers in my 2015 mini Cooper S straightforward installation in great sounding speaker. Iโm glad I purchased these.
User
Size misleading but Great sound
Leaving 3 stars only for misleading size. These are listed as 4โ speakers and do not fit the enclosure i have that had another brand of 4โ 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.
