No, tonally balanced desired, no favoring of treble or bass over the other.
All my house`s room`s stereos, less the living room`s reference system, have at least one sub woofer to supplement the various book shelf type speakers in use`s weak bass.
However, my sunroom`s DQ-10s have L/R Velodyne 15" 400 watt servo powered subs to compliment their weak bottom octave, and those speakers are far from bookshelf in size.
The same Velodyne powered subwoofer setup is used in my bedroom`s stereo setup to supplement the weaker bottom octave of the Mc. XRT-18s in use there.
Well recorded digital music sounds well tonally balanced on any of them, so the lessor quality originally recorded (but desirably written/played music) that comes across these systems is either tolerated, or the player is advanced to the next track of my all day playing WAV. ripped multi-genre currently 15k digital music tracks.
Majority of this house`s stereos tone controls are set flat, and when played at conversational playing SPLs, I might have the receiver`s, or preamp`s loudness function engaged to obtain a tonally balanced SQ.
First time visitors, over the yrs., have on occasion, complimented me on the clear sounding balanced SQ of these stereos as we walk through the house being exposed to the different room`s playing stereos.
All set up for my desired SQ tastes, if others agree, fine, if not, oh well.
