.....broken....man that hurts a bit, but i understand....
i have spent last several weeks breaking in and dialing in the Treo CT ( which you know do not have powered bass ).... then came “ home “ to Seattle to the 7’s......€¥&*@@@@@@@ !!!!! holy, what is missing....that bottom 2 octave wallop....
but it aint fair, with amps 16:1 money......and a condo with subwoofers essentialy banned ( self imposed )
i will say in the Treo and the Quattro for that matter ( some value for the OP ) what is not missing is absolutely seemless driver integration in the treble, critical midrange, the midrange driver is very very good. With a Basis / Delos front end it is liquid smooth with superb depth of image....Eva can make me cry, as she does on the 7
i would continue to hone your setup ;-)
