This whole matter might be settled this month by about 25 attendees in blind vote!

Three of the four systems on this tour are capable of strong subsonic frequencies and desertdome is a strong EQ personality on AVSforum.
He's toying with the idea of setting up some blind EQ settings where a different HPF is employed to see if people can identify which of the EQ's passes the lowest frequency reproduction.
IE --- setting up a HPF at 20hz, 15hz, 10hz, and 5hz. Playing back the same track and seeing if the 25 attendees can blind vote on which FR is which. He would setup the test before hand and ensure the three EQ settings are all identical down to the HPF.
One setup has four UXL 18's.
One setup has a DTS-10.
One setup has eight 15"s in an infinite baffle arrangement.
Possibly three different rooms, three different setups, about 2 dozen blind voters
if done right it could be pretty definitive testing day to the value of subsonic frequency in movie reproduction.
