Hey guys need a little help. I am not the most savy when it comes to stereo install / equiptment. I have had a set of Infinity perfect components, just recently both the woofers blew. So I am thinking of replacing the woofers with a set of MB QUART QSC 164 mid bass speakers.

- These pretty decent speakers?

- I am keeping the Infinity tweeters, should I keep the Infinity crossover as well or swap in the one that come with the MB QUART's.

 

i don't like MB Quart .. they sound too muddy.. i would go with Diamond Audio Hex Series instead

 

The thing with components sets is that they are designed as a complete set. The crossover points/slopes/topology is designed for the specific drivers in that set. The tweeters and woofers are matched to each other and compliment each other. I recommend highly against just dropping in a different woofer or tweeter without a good bit of research first. Ideally you should find out the parameters/specs of the infinity woofer and find a driver with the same specs. If you pick a woofer with completely different specs it will most likely not sound good.
