Just have to hear it to believe it. You get more than what you pay for in this case! Clean and crisp sound no complaints! So far I've had them for about 6 months and still to this day they sound just like when I bought them. Thank you Sonix Electronix for making it possible to purchase this product!!

I AM PLEASED WITH THIS PRODUCT. I HOOKED THEM TO AN ALPINE OLD SCHOOL AMP AND I'M HAPPY WITH THE SOUND

Good, I would buy them again they are worth checking out.

I first was introduced to MB Quart speakers in 1989 when I bought my 2nd VW Rabbit GTI. I wish I still had that car and those speakers. Fast Forward almost 25 years. Now I've graduated to Mercedes but I still sought out these MB Quart Speakers trying to bring back that acoustic divinity of last century. Do these do it? Well, my problem is, I don't have the duel 12" Rockford Fosgate subs in the trunk. So, that being said, these sound just about as good as they did when they were made by the old skewl manufacturer. OH... the one thing I don't like about them? Being old skewl, I'd rather have the black screen cover rather than the new shiny silver design they have. Kinda looks out of place in a classic Mercedes. But they're no big deal.

This version replaced a previous model I already own. The crossover on these appears cheaper, but functions well. I can't comment on the tweeters as I am using a different tweeter in my application. I am not maxing these out by any means, but the sound quality is excellent. The grills are ugly and wont protect the speaker at all.

I did an install on a friends car so i didn't get to hear them extensively but for the moment i did while i was tuning them they played really well, especially considering how cheap they are i would get another set.
