I got these speakers for my "budget" system replacing the stock speaker setup in my '02 Forester. I've been building up my system in stages first replacing the head-end with a Kenwood KDC-X596 (excellent!!!). I've since added the MB Quart ONX216 separates for the front and purchased the ONX157s as fill speakers in the rear doors kick panels. As the stock rear speakers are a bit odd 4-1/2 size, it took some significant cutting and fabrication to fit the space.

The effort was well worth it. As expected, the ONX157 are a far more efficient than the speakers they replaced. The mid-bass response really rounds out the sound, but I have to admit that I'm a bit surprised at the lack of high end reponse from the 30mm tweeters. I'm sure its location so low and forward in the rear doors don't help. Clarity and detail are impressive for a "budget" 2-way. I'm expecting performance to improve once they break in.

I'll be adding an amp (ONX4.60) and an 8" sub to complete the system. I had planned to run the fronts and sub off the amp and continue to run the rears from the receiver (22w), but they may need a bit more power to improve imaging and soundstage.

The ONX157 speakers are a solid value-for-money. The construction and build quality are about as good as it gets. The magnet size is considerable and immediately reassures that you've got a quality product. Highly recommended.

Great speaker for the money. Definitely an entry level Quart but great sound reproduction non-the-less. I wasn't going for professional level audio just something better than stock. I have a ford pickup and WOW did these speakers wake up that factory deck. I'd say not only a clarity/detail improvement but a Volume level improvement aswell. The only thing they lack is bass but really its a 5x7 what do you expect. (Also I'd like to add the placement and size of cab are not lucrative to good bass. Oh and they are a million times better than the factory speakers.)
