Powering DQ-10s

I have just re-foamed a pair of matched Dahlquist DQ-10s and want to use them in my home theatre system.  Also will be using a DQ-1w sub, but will probably need to re-foam the 13" driver first, as it looks like it's never been touched since new in the '80s. Where might I find a foam ring/kit for that?  I don't see anything online other than for smaller DQ drivers.  Also, would 200w/ch be enough for the three spkrs?
Thanks!
