I am so happy I found this thread, as I almost created another for my situation. It seems much more appropriate to just post here.
I recently bought Energy Micros which I am yet to set up (we are in the process of buying a house now). My sub search has revealed two main issues. First is a possible frequency hole from 150 Hz down to whatever the sub can hit. However, looking at this graph http://www.hometheater.com/content/energy-rc-micro-speaker-system-ht-labs-measures
seems to indicate the Micros are still producing at decent levels down to at least 140 Hz, so that may not be as big of a deal. The second issue is that, while I really would like to get a 12" sub, I'm reading 12" subs in general do not match well with small speakers (possibly this is really the same issue as the first).
I really can't see myself going above $200, and I'm sure it will be a challenge to convince the wife to go above $100 (though all of my candidates would require that). After reading this thread, I had pretty much decided on the S10.3 despite the fact the specs indicate a significant frequency hole from 120-150Hz. However, Newegg has now discontinued it (like they did with the Micros previously). Oh well.
My candidates at the moment seem to be...
-Bic F12: It's frequency range (25-200 Hz) makes it appear on paper to be more than adequate to match with the Micros. But am I expecting a 12" sub to play too high too much? I'm not crazy about front firing as well because it's not as kid proof. Plus it's toward the top end of my budget.
-Dayton Sub 1000/1200: If it had a slightly higher frequency response, it would probably be at the top of the list, but it tops out at 140 Hz again leaving a frequency hole. I prefer the 12" version because it is the same price with the ability to hit lower frequencies (30 Hz vs 35 Hz), but if the 10" is a better match for the Micros, so be it. I really wish there were frequency response graphs for this speaker. I also am confused as to whether it is down firing (as the verbal description says) or front firing (as the pictures seem to clearly indicate).
-Bic V1020/V1220: With specs topping out at 180 Hz, these again seem a potentially good match. And unlike with the F12, there is a 10" version that maybe is a better match for the Micros. Plus it is downfiring.
-Anything else that might be suggested
I wish I could say the Jamo Sub 650 was on the list, but I just don't know if I can swing the budget, especially since it is no longer available at $250 (though I did briefly see a $242 open box on Vann's today).

Any suggestions or thoughts?
