When I first looked at the charts I noticed they started to fall off at about 60hz also.I have mine in a 2.1 set up,so what I did was I got an Outlaw Icbm to do the crossover work.I set the crossover at 60hz going to dual Hsu Vtf-2's.Its all good now.I would think the -3db would be lower with in room response though.
