Thanks for the input... yea I'll probably just go the coaxial route for the rear for the cost savings if nothing else...
rainbow sl100 - have my attention right now.
For the front I'm still considering primarily the Dotech Ovation Comp 4 - Morel 4" 2-Way Component System
But now that I'm saving a bit on the rear, I'm considering 'stepping up' (if it is indeed a step up I'm not sure) to the: CS 210 PROFI - Rainbow Profi 4"
My thought process is the Rainbow Profi's require a bit less in power which may end up sounding better with the 600/6
Still hoping to hear from Technic soon, but I figure its the weekend so hes likely out having a life lol (how dare him)
