Built Quality.
The package came with all necessary extra things required to fit in my 2015 BMW 320i. I was totally loved the sound. Just on the high end volume I heard little distortion. But it's way better than the stock BMW speakers. I would recommend it.

Nice Upgrade
If your issue is trying to get rid of that “hollow” stock speaker sound (without breaking the bank) while adding some high fidelity get these and sound proof your doors with Dynamat. I have stock hifi amp and these sound very good. Gives you four tweeters in front and two in the rear when finished. Connect phone to USB, keep bass at half way or less with your phone’s EQ flat.

Great sound
Sounds much better than Hi-Fi option. Got 3 pair to replace 5 speakers in a 2017 X1.

Crackle fresh out of the box
Bought this for my 2011 e90 and they fit like a dream, BUT the tweeter built into it sticks out past where the door covering sits so I had to doctor that but now that it's all plugged in the right sounds so quiet and the left sounds great. The right also has a slight crackle already fresh out of the box and that is gonna drive me up the wall. It's kinda hard to mess up plug and play so I know I wired it properly. I just don't get it.

Great BMW fit and good sound
Looking to upgrade or replace stock BMW door speakers in your e9x, then get these! Comes with everything to plug and play with zero modifications needed to your interior. Much better and cleaner sound from these speakers.

Great upgrade for F22.
Replaced all 5 speakers in my M240i that was equipped with the base version "HIFI" system (no tweeters). Substantially improved sound over the factory speakers. I do find them to be mildly bright but not obnoxious so. Dropping the treble by one step sounds best on most program material. Fairly easy installation and the kit contains everything needed for mounting in all locations.
