I got in on the Jan 1st special and purchased a set of Mach 5 Mli-65 mids. I've been planning a 2 way setup for my S10 that will run these mids, a passive crossover, and the North D25 tweeters. This will run off of either 2 channels of a Punch 600.4, or one of my Van Gough 600's. The setup is going into the door panels on an MDF baffle board that I'll be building soon. My question here is these tweeters are a low FS design and run at 6 ohm, the mids are 4 ohm. I found a set of Boston passive crossovers that're rated at 2700hz and I'm assuming they're rated at 8 ohm, here's the link: http://cgi.ebay.com/Boston-Acoustics-2-Way...1QQcmdZViewItem If these are rated at 8 ohm, that should give me an 1800hz crossover point on the tweeters correct? I'm still debating on if I should chance a set of these crossovers, or if I should just fab up seperate crossovers for the tweeter, and the woofer. I already have the mids, but I haven't purchased the tweeters or crossovers yet. The NorthD25's just seemed like the best deal going for a Low Fs tweeter to mate up with these mids. Thanks in advance guys.
