Summary: These speakers are a great value and sound pretty good. The outside mounting dimension is a little larger than your standard 6.5 in speakers. I had to make some modification to my radar arch to make them fit. The magnet is very large so ensure that you have plenty of clearance behind the speakers.
Lasted five seasons, plastic cone disintegrated due to UV.

Summary: Well, I came here to to complain about longevity - because one of the cones has basically fallen to pieces - it has cracked and is no longer attached to the surround. Cones are made of plastic, and I don't think they did so well with UV.
Summary: Pretty heavy duty. Sounds good. If you're a bass lover, could use a sub woofer with these, but for general purpose good sound, these are fine. Make sure you have clearence behind when mounting. These are deeper than many speakers and have a large magnet.
