Hi all,
I am very new to the Altec world and despite a lot of online research remain confused......I have the following 'bits' : 902-8A, 811B, 416-8C & A7 enclosures, I do not have a crossover. I think what i have is Model 19 drivers and an A7 enclosure, is this correct?

Money is unfortunately tight for me so I will not be buying any other driver/enclosure bits. Also due to financial constraints i am (obviously) rather nervous of blowing a driver. i intend building a crossover myself and would prefer a passive crossover (safer) but active will be quicker to whip up initially, so my questions are:

1. What crossover frequency?
2. What slopes?
3. Which Altech passive crossovers (if any) can i use?
4. If anyone has some schematics for suitable passive networks could you please pass on or point me at them?
5. I have seen many crossover schematics but they look rather complicated obviously some additional EQing is going on what corrections are these relevant to my 'bits' of course?

If i am posting on the wrong forum i do apologise. Any assistance will be greatly appreciated.
