The price paid for these, especially when on sale, leaves little to be desired. The characteristics of the sound are very natural, which is asking a lot these days. The tweeters are bright without being harsh, and the midbass drivers deliver solid response without being overwhelming.
-Lots of hardware; Lower than 4ohm impedance for squeezing a little extra out of an amp; Natural sound without being harsh on the highs; Excellent mounting options
-That low impedance maaaaaybe would aggravate the protection circuit in some more sensitive radios if they're running 2 pairs (I'm looking at you, Kenwood circa 2013); Run with an amp to ensure no issues either way
