Summary: This is a nice speaker well built. The sound is comparable to mb quart. These are marine speakers so I expected the sound the to be high and it is, but the clarity should be a little clearer for the price.
Pros: seem to be built well nice one piece design with the built in crossovers
Cons: The screws need to be longer ,boat speakers are mounted with backing plates.
Summary: I looked at a lot of different speakers and there reviews, but then I came across these JL audio m770-CCX and thought if I really wanted to spend the extra money, so I only purchased two out of four speakers and now I can't wait to get the other two replaced.
Pros: Easy hook up for someone like me that never did this before. Very simple
Cons: A little pricey but it was well spent money. No regrets
Summary: Hand's down these will finally be the last speakers I install in my boat. After trying about 5 pairs over the years, these have the power capacity and quality to provide lasting high levels of output for extended periods of time.
