loud and clear is correct
I own one pair of these, a pair of 6.5", and 4 pairs of 8" in the RF PPS4 series. I think these are a fantastic line of speakers. These are being marketed as "loud and clear" and they live up to that slogan. These are a great choice in any custom car audio or home audio installation, especially where the speakers will be required to be pushed at above average SPLs.
Pros: They push the important part of the audio spectrum frequencies at very high volume levels without distorting. They are big, beefy speakers designed to blow heads in a car audio system and sound great doing it.
Cons: Wish they had a little more high end, i.e., the frequency response went to 5K. Otherwise perfect.
