Clean, big sound

These speakers sound great and are a huge upgrade from the stock speakers. I have a 2008 3 series running a JL XD600/6v1 amp. The only tricky bit of install was that there are a different number of screws on the mids than the stock. It was easy enough to screw them into the door fiberboard. The tweeters install wasnt hard but I used some glue to fully secure them. Given the limited number of speakers in this car, these are a great upgrade in the overall sound. I had these previously in both the rear deck and front doors since 2008. One crossfade died and I blew out a tweeter and mid in the front after 10 years (also potentially related to a rain storm and wet door) so I felt confident buying these again. The speakers in the rear deck that are 10 years old still sound great. Now with the front working again the whole ensemble sounds great.

Pros: 60 Watts RMS is plenty loud with the JL XD600/6v1 The mids and highs are clean Everything fits within the previous spaces so you cannot tell there are aftermarket speakers until they turn on The sound quality improvement is night and day They seem to put up with a lot of abuse and high volumes for many years

Cons: Installation of the filter in the door isnt hard but it isn't the most secure location. The number of screws for the mid is different than stock You have to break off the tweeter plastic rim to get it to fit into the old tweeter location

Benchmark 4" and Tweeter Combination

I do not have a whole lot of time with these speakers yet to tune them with their crossovers, but for a 4" and tweeter combination it seems about as good as it can be. I will be expanding the power to the speakers soon as well. When installed in the rear speaker positions (1996 Porsche 993 Targa), they dominate the Hifi equipped car with a much bigger sound. The tweeter is a little on the bright side, but I have them aimed forward with the provided, installed cup from Focal. They are also currently set to +3, and could use some adjustment. These replace the stock 4x6 rear speakers. The quality is second to none. Aesthetically pleasing.

Pros: Big, precise sound compared to 4x6 speakers. Quality. Handsome and befitting of a classic car for the music lover with the ability to handle quite a bit of power (60W).

Cons: Expensive.

Clear and crisp

A great component speaker in a 4" package. The tweeters are simple to mount although + and - are not indicated anywhere. The crossovers keep the speakers distortion free.

Pros: 4", component with crossovers, great sound, easy to mount tweeters, compact.

Cons: Instructions could be better.
