Thanks to all for the feedback.
I plan to get a BFD this week based on all of the overwhelming success everyone here seem to have with it. It should get the response reasonably flat down to around 18hz. Pretty wimpy compared to thxgoons system, but I think I'll be ok with that
I will definatly post before and after graphs for everyone if I get a BFD.
I'm only using a 250W amp (NHT A1) to power the subs. WINISD is calculating 119db which should be plenty for me. WAAAYYY to much for the wife. My rear projector tv gets blurry on the lower frequencies as it is. I dont think it would be enjoyable to watch if the SPL's get much higher. Might be fun for an audio demo though
Warmon - keep us posted with your nightstand project. The quality of your "three sons" was incredible!
