You gents keep on repeating the same thing. My intention is NOT to build a perfect and correct speaker set up with all correct speakers and crossovers. My intention is only the following 2 options(before i buy a new 3 way speaker set some years from now), to either use the 6 db crossover i currently have with the new 8 super bullet tweeters,bass,mid, OR find a 12 or higher db crossover to almost meet the 25Khz(2000 hz-25000 hz) highs of these super tweeters since the max tweeter freq i get with my current crossover is only 7Khz(5000hz-7000hz).No other options im interested in as of now, for example not interested in starting from scratch, ONLY interested in the 2 options i listed no matter what the outcome.Get it? Lets hope one day ya could buy a simple PLUG AND PLAY tweeter, bass woofer and midrange that all have a built in crossover in each and all you need to do is connect left and right wire from any receiver and they all sound perfect, lowest lows, highest highs and mid like their supposed to.
