I was curious because if the drop off below 30 hz wasn't as dramatic as I now see with that graph, perhaps some EQ drop at 40hz+ and gain below 35hz could at least allow it to produce decent low level bass to 110 dB at 20hz & 116 dB at 25hz or so, (throwing random hopeful figures out since I don't have actual measurements) which would make it at least usable, even if it has nothing below 18 hz, especially if you listen to more music than movies. and yes I meant DXS18 not 12, not sure how it ended up like that in the post. I must admit I do love the chest slamming bass more than the room shaking bass, so my love for PA speakers will be there regardless of how not-so-low they go.
