well two years with out tunes is enough for me, so i am thinking about putting a stereo in the k5. a few years ago i was big into stereo competitions. and back then i always used Image Dynamics compression drivers for my highs, MB Quart for my mids, and JL Audio for the subs.. i will still be using JL Audio for my subs but since it has been a few years since i have looked at speakers..Do any of you know if the Image Dynamic compression drivers and the MB Quarts are still any good? at the time i was using them, they were one of the best, and during that time 9 out 10 winning cars used MB Quarts..and I really enjoyed the qualty of sound they put out. and my personal opinion is that compression drivers are the only way to go for highs.. so who useses these brands? whats your opinion of them?
