I have been running a set for about a year now being powered off a DLS A3 receiving 270wrms per side. Pro's -Midbass monsters -Very defined and tonal -Tweeters not harsh at all -Excellent Xover's provided -Extra power doesnt seem to affect them at all -One set manages to keep up with a 145db set up. Con's -Motor is absolutely huge and will require custom housing in most cars Other than that I cant say a bad word about them. Hope that helps.
