I'm new to this site and well behind the curve on what's out there. I have a pair of Avantgarde Trios with 2 pair of 225 subs. I've recently moved the speakers to a converted barn (dimensions 52 'X 34', side walls are 12' high with a 24' peak. The Avantgarde woofers can' t keep up in this space so I'm looking to add a pair of subs that will match well for music and HT usage. I have a wood shop so DIY is an option. We do have occasional dances at loud levels. I am curious about the Danley DTS 10 or 20 but I'm not sure if they are still made. Any help is appreciated.
