Strengths: These components have fantastic sounding midbass. I have them installed into my door panels with full length wood baffle boards and the sound is great for the price paid.
Weaknesses: The tweeters can be a bit harsh at times and the mids will pop at higher volumes. I need to cross them over at 125hz to play them at very high volumes. I liked the vocals from mb quarts better.
Summary: I have about 4 days on my current install using all cadence speakers and orion xtreme amps. Because of the volume I am looking for I may try some hcca components. With a little more dialing on the system this may change.
Similar Products Used: I have had a few year old set of Polk audio mm and a set of mb quartz 216 installed in the same matter. For the money they are great and could sound good as a stand alone factory upgrade.
